Methods

Enhancing the development of low-emitting products and materials

This Application Note describes how sampling technologies for thermal desorption that are typically used by test laboratories for screening products for chemical emissions can also provide manufacturers with tools that greatly aid the development of low-emitting products and materials, and thus compete in the expanding market for ‘green’ products.

 

Improved Resolution of Triazine Herbicides with Kinetex Core-Shell HPLC/UHPLC Columns and Zebron GC Columns

Environmental laboratories are continuously pushed to deliver lower detection levels and faster sample throughput. A common analysis performed by these labs is triazine herbicides. This analysis can be performed by LC/MS/MS or GC/MS, for which Kinetex core-shell UHPLC/HPLC columns and Zebron GC columns provide resolution and sensitivity improvements as well as time savings.

 

Derivatization Reagents: For Selective Response and Detection in Complex Matrices

Derivatization is a commonly used technique to augment chromatography analysis. It requires efficient and effective reagents that can modify the behavior of complex compounds and allow their detection in chromatographic analysis.

 

Comprehensive Determination of Trans Fats in Cookies using SP-2560 and SLB-IL111 GC Columns after Silver-Ion SPE Fractionation

In this application, we have demonstrated the extraction of lipids as fatty acids, and subsequent detection of trans fats from a cookie sample made using partially hydrogenated vegetable oils.

 

Analysis of Residual Pesticides in Processed Foods Using GC-MS/MS

This application datasheet presents a study of an analysis of residual pesticides in retort-packed curry using QuEChERS and GC-MS/MS. QuEChERS method is commonly used for vegetables due to its speed and simplicity. While GC-MS/MS is able to selectively separate residual pesticides from a large quantity of co-extracted substances.
