B

Bisphenols by LC-MS/MS (APK #601)

Bisphenols are widely used in food packaging in the production of internal coatings to protect food and beverage from direct contact with metal. Residues of bisphenols can migrate into foods and should be strictly monitored due the harmful effects on living organisms at low doses. This application shows the simultaneous determination of BPA and other bisphenol analogues at the traces concentrations levels.

H

Herbicides by LC/MS (APK #357)

This application shows the separation of selected herbicides from the picolinic acid and phenoxyacetic acid family.

P

Pesticides in environmental matrices (APK #629)NEW

This application describes a quick and robust LC-MS/MS method for simultaneous analysis of residual concentrations of pesticides in water matrices. The method provides a good separation and quantitative determination of pesticides and their isomers. Micro-Solid-Phase-Extraction (MSPE) has been used for sample clean-up.

Pesticides play a critical role in food protection against pathogens and pests. However, pesticides pose significant risks to non-target organisms, including animals and humans. The number of pesticides is continuously growing as new active substances are being developed. For this reason, a robust and reliable method for simultaneous determination of multiple analytes, is very relevant today. ASTRA® Pesticides column is designed
for routine environmental analysis and provides reliable retention under high-aqueous conditions for wide class of compounds including triazines, chlorophenoxy acids, organophosphates, fungicides and herbicide metabolites.

Photosynthetic pigments (APK #483)

This application shows the method of analysis of the main photosynthetics pigments in extracts of Hibiscus leaves and extract from cells of the algae Emiliania huxleyi. ASTRA® C18-HE column allows to achieve good separation of the pigments, which is always challenging.

Polar pesticides by LC-MS/MS

Polar pesticides are commonly used in agriculture. This application shows the LC-MS/MS method for simultaneous determination of highly polar pesticides paraquat, diquat, chlormequat and mepiquat.

Сhemicals of emerging concern in river water (APK #469)

The chemical pollution cause huge damage to the aquatic environment.The simultaneous determination of pollutants with different physico-chemical properties, such as pesticides, metabolites, personal care products, plastic-related chemicals is always challenging. The application shows a sensitive LC/MS method for fast determination of diverse group of pollutants in river water.
