The 2024 AOAC INTERNATIONAL Annual Meeting & Exposition was held in Baltimore, MD, UDA. Shimadzu participated in the science sessions, presented posters, and held corporate exhibitions to provide insights on food analysis, while engaging with many attendees.
Overview of AOAC INTERNATIONAL
AOAC INTERNATIONAL was founded in 1884 under the USDA and US FDA as an independent, non-profit membership association of analytical science professionals from government, industry, and academia worldwide. This organization consists of scientists, government officials, and other organizations involved in the validation of analytical methods and procedures, practical analysis, and quality control in the field of analytical science. With approximately 3,000 members from around 90 countries, there is a significant presence in the United States. The association鈥檚 activities include the review and supervision of AOAC Official Methods, training, and hosting the Annual Meeting. The 2024 AOAC INTERNATIONAL Annual Meeting & Exposition was held in Baltimore from August 23 to 28. The annual meeting included a space for interacting with other participants and providing technical information, such as conducting scientific sessions, presenting posters, or displaying corporate exhibitions. The meeting covered a wide range of topics, surrounding food quality and safety. Key topics included nutrients and functionally beneficial ingredients in foods and supplements, but chemical substances, natural toxins, pollutants, and other residual substances contained in food and packaging took the largest share of conference time. Given the growing demand for faster, more streamlined analytical methods, there is an increasing amount of research on utilizing automation and AI technologies. Especially notable were sessions and poster presentations about analytical case studies on the current status of harmful pollutants and residual substances, particularly per- and polyfluoroalkyl substances (PFAS) or mycotoxins.
Shimadzu Group Activities
At this meeting, Shimadzu participated in a variety of activities, including serving as symposium chairs, and hosting vendor seminars and exhibitions. During the conference proceedings. Shimadzu provided information about PFAS, ethylene oxide (EtO), and other topics in oral seminars,roundtable panels, and hosting vendor seminars. For PFAS, Shimadzu developed a single LC-MS/MS method that can be used for the 11 food categories addressed in AOAC SPMR 2023.003 and discussed factors that should be considered for PFAS analysis. The topic generated the most interest as Shimadzu was one of only 4 submitters of methods to the SMPR. Shimadzu routinely participates in AOAC by submitting analysis methods, participating in working groups and advisory panels and presenting at the annual conference.
At poster sessions, Shimadzu presented research results on 25 topics. The poster sessions featured many examples of using LCMS and GCMS systems for PFAS analysis and provided knowledge about not only food but also food packaging. A wide variety of instruments, such as LC-MS, GC-MS, ICP-MS, HPLC, and FTIR systems, were used in presentations on a wide range of topics, such as nutrient components,aroma components, pesticides, PAHs, MOSH/MOAH components, and inorganic elements. Participants asked questions about factors to consider and detection sensitivity for analyzing food samples that contain a large number of contaminants. Shimadzu presentations can be viewed via the Shimadzu website.
This year, Shimadzu gave presentations on new LC-MS and GC-MS products.Of those, a presentation on the new GCMS-QP2050 system was given in the corporate exhibit area. In addition to superior robustness and reliable performance, the system also includes software with automation technology.For GC-MS systems, a presentation was given on analyzing pesticides, PAHs, and aroma components. Using a hydrogen carrier gas for pesticide analysis attracted the most interest. During the AOAC meeting schedule, many attendees participated in tours of the nearby SSI laboratory. The tours provided an opportunity for participants to freely discuss PFAS analysis with LC-MS and GC-MS engineers. Participants shared comments about struggling with contamination originating from working environments and with detecting trace concentrations. Given Shimadzu鈥檚 involvement in a variety of research on food samples, Shimadzu engineers provided information about how different matrices can affect analytical results. The fact that Shimadzu engineers in respective regions have been working together to study and share information about PFAS was also highly appreciated by participants. The PFAS logo themed laboratory coats worn during the tours were also very popular and offered as souvenirs. The AOAC is an organization that provides important analytical methods referenced throughout the world and its annual meeting offers exposure to a large amount of technical information. Shimadzu will continue to offer solutions useful to customers based on the feedback received from participants about the information provided by Shimadzu. In 2025, Shimadzu are planning many poster presentations on PFAS, allergens, heavy metals and microorganisms, and vendor seminars on Screening for EtO and 2-CE by HS-GC-MS/MS.

‘I felt you did: I don’t know why,’ she said. Life on a steamship at sea has many peculiarities. The ship is a world in itself, and its boundaries are narrow. You see the same faces day after day, and on a great ocean like the Pacific there is little to attract the attention outside of the vessel that carries you. You have sea and sky to look upon to-day as you looked upon them yesterday, and will look on them to-morrow. The sky may be clear or cloudy; fogs may envelop you; storms may arise, or a calm may spread over the waters; the great ship goes steadily on and on. The pulsations of the engine seem like those of the human heart; and when you wake at night, your first endeavor, as you collect your thoughts, is to listen for that ceaseless throbbing. One[Pg 53] falls into a monotonous way of life, and the days run on one after another, till you find it difficult to distinguish them apart. The hours for meals are the principal hours of the day, and with many persons the table is the place of greatest importance. They wander from deck to saloon, and from saloon to deck again, and hardly has the table been cleared after one meal, before they are thinking what they will have for the next. The managers of our great ocean lines have noted this peculiarity of human nature; some of them give no less than five meals a day, and if a passenger should wish to eat something between times, he could be accommodated. Another condition of apprenticeship that is equally as difficult to define as the commercial value of mechanical knowledge, or that of apprentice labour, is the extent and nature of the facilities that different establishments afford for learners. Bang! The shutter was closed again. But I did not give it up, for I needed the sisters' assistance to find a shelter somewhere. Once more I made the bell to clang, and although I was kept waiting a little longer, at last I heard voices whispering behind the gate and once more something appeared behind the trellis. Such a view was essentially unfavourable to the progress of science, assigning, as it did, a higher dignity to meagre and very questionable abstractions than to the far-reaching combinations by which alone we are enabled to unravel the inmost texture of visible phenomena. Instead of using reason to supplement sense, Aristotle turned it into a more subtle and universal kind of sense; and if this disastrous assimilation was to a certain extent imposed upon him by the traditions of Athenian thought, it harmonised admirably with the descriptive and superficial character of his own intelligence. Much was also due to the method of geometry, which in his time had already assumed the form made familiar to us by Euclid’s Elements. The employment of axioms side by side with definitions, might, indeed, have drawn his attention to the existence and importance of judgments which, in Kantian terminology, are not analytic but synthetic—that is, which add to the content of a notion instead of simply analysing it. But although he mentions axioms, and states that mathematical theorems are deduced from them, no suspicion of their essential difference from definitions, or of the typical significance which they were destined to assume in the theory of reasoning, seems ever to have crossed his mind; otherwise he could hardly have failed to ask how we come by our knowledge of them, and to what they correspond in Nature. On the whole,385 it seems likely that he looked on them as an analysis of our ideas, differing only from definition proper by the generality of its application; for he names the law of contradiction as the most important of all axioms, and that from which the others proceed;277 next to it he places the law of excluded middle, which is also analytical; and his only other example is, that if equals be taken from equals the remainders are equal, a judgment the synthetic character of which is by no means clear, and has occasionally been disputed.278 387 We have now reached a point where Greek philosophy seems to have swung back into the position which it occupied three hundred years before, towards the close of the Peloponnesian War. The ground is again divided between naturalists and humanists, the one school offering an encyclopaedic training in physical science and exact philology, the other literary, sceptical, and limiting its attention to the more immediate interests of life; but both agreeing in the supreme importance of conduct, and differing chiefly as to whether its basis should or should not be sought in a knowledge of the external world. Materialism is again in the ascendant, to this extent at least, that no other theory is contemplated by the students of physical science; while the promise of a spiritualistic creed is to be found, if at all, in the school whose scepticism throws it back on the subjective sphere, the invisible and impalpable world of mind. The attitude of philosophy towards religion has, indeed, undergone a marked change; for the Stoic naturalists count themselves among the159 most strenuous supporters of beliefs and practices which their Sophistic predecessors had contemned, while the humanist criticism is cautiously guarded by at least an external conformity to established usage; but the Platonic doctrine of immortality has disappeared with the dogmatic spiritualism on which it rested; and faith in superior beings tends to dissociate itself from morality, or to become identified with a simple belief in the fixity of natural law. One temple to Buddha only, on an elongated plan, ends in a vault forming a bulb-shaped cupola supported on massive columns, quite Byzantine in character and wholly unexpected. The dim light, coming in only through a low door and two small windows filled in with pierced carving, enhances the impression of being in some ancient European fane, and the Buddha on the high altar has a look of suffering and emaciation that suggests a work of the fourteenth century. The man was dressed in blue and silver, his belt studded with four-anna pieces; hanging to his girdle was a whole array of small knives, sheaths, and boxes. With his sleeves turned up to his elbows, he fairly amazed me, conjuring away into the air eight rupees that filled his hand, and finding them again one by one in our pockets, bags, or plaids. He turned everything topsy-turvy, swaggered as if he were the master, and then went off, with his broad smile, to amuse other travellers. “Well,” Sandy grinned, “the chewing gum disappeared! Supposing the fellow we thought we saw vanishing really was there and got out some way. He’d know, from Jeff landing us and our going in, that the amphibian might not be usable when he’d need it——” She reloaded for him, and fired from time to time herself, and he moved from the little round hole in the wall to one in the window blind, in the feeble, the faithless hope that the Indians might perhaps be deceived, might fancy that there was more than the one forsaken man fighting with unavailing courage for the quiet woman who stayed close by his side, and for the two children, huddled whimpering in one corner, their little trembling arms clasped round each other's necks. Back of her, a score or more of miles away, were the iron-gray mountains; beyond those, others of blue; and still beyond, others of yet fainter blue, melting into the sky and the massed white clouds upon the horizon edge. But in front of her the flat stretched away and away, a waste of white-patched soil and glaring sand flecked with scrubs. The pungency of greasewood and sage[Pg 313] was thick in the air, which seemed to reverberate with heat. A crow was flying above in the blue; its shadow darted over the ground, now here, now far off. "The very same company," gasped the woman. The firing grew pretty noisy. "Off!—where?"
