This article highlights the work of analytical chemist Dr. Yeru Huang and colleagues at one of China’s premier research centers (National Research Center for Environmental Analysis and Measurement). Collaborating with the United Nations. Dr. Huang’s activities, supported by Shimadzu Corporation, are at the forefront of research on POPs.

Shimadzu’s app note demonstrates the sensitivity of the LCMS-8060 when analyzing dicamba and 2,4-D in a solution of 100x diluted glufosinate herbicide that contains a high amount of surfactants and other potential mass spec interferants.
The LC/MS/MS method was quickly developed with readily available mobile phases. Dicamba in methanol 0.01 and 0.025 ppb had a S/N of 3/1 and 10/1, respectively. 2,4-D in methanol at 0.0001 and 0.001 ppb had a S/N of 13/1 and 90/1, respectively.
Due to customer demand, IDEX have increased the number of length and ID configurations from our initial eight, to a selection of 55 robust configurations.

Antibiotics present in food pose a serious public health issue. Allergies to sulfonamides are very common, and the increasing popularity of antibiotics is driving microbial resistance against current antibiotics.
Monitoring the Maximum Residue Levels (MRLs) has proven essential for public health, with the MRLs for some compounds set to low ppb levels. HPLC-MS/MS is very effective at analyzing trace-level antibiotics because it is selective, fast, and very sensitive for all the compounds of interest.
