A confirmatory method for 6 penicillin antibiotics (amoxicillin, ampicillin, penicillin G, oxacillin, cloxacillin, and dicloxacillin) in honey is presented that allows determination and confirmation of identity of the antibiotics at trace levels.

Liquid chromatography?electrospray ionization mass spectrometry methods (LC-ESI-MS and LC-ESI-MS/MS) for the determination of five macrolide antibiotics including spiramycin, tilmicosin, oleandomycin, erythromycin, and tylosin in honey are presented.

Streptomycin belongs to the group of aminoglycoside antibiotics. It was utilized in apiculture to protect bees against a variety of bee diseases. It was the aim of this study to develop a highly sensitive LC/MS/MS method, which could be validated, for the quantitative determination of streptomycin in honey.

This paper describes the principles, the current technology and the applications of HPLC and tandem mass spectrometry (LC

Baby bottles are often made of polycarbonate plastic. Impurities remaining in the bottle from the monomer bisphenol A can migrate from the plastic bottles into baby food, thereby causing a health concern. Previous migration testing of new baby bottles showed only trace migration levels of the substance. In the present work, polycarbonate baby bottles were subjected to simulated use by dishwashing, boiling and brushing. Migration testing performed with both new and used bottles revealed a significant increase in migration of bisphenol A due to use.
