The Food and Drug Administration (FDA) in the USA and the European Commission in the EU has established lists of tolerance levels, also known as maximum residue limits (MRLs) for different food contaminants in different animal edible tissues.

Why Outsourcing Chromatography is a Valuable Option.

Isolation and purification techniques play a massive role in drug discovery. Being able to strategically control your synthetic route is vital. In recent years both High Performance Liquid Chromatography (HPLC) and Supercritical Fluid Chromatography (SFC) have provided high quality compounds for biological testing cheaply and to time. With shorter turnaround times required, alongside increased throughput and cost restrictions, purification departments are being pushed to the limit. This is no…See More

Manual headspace GC troubleshooting

Hello, I am trying to measure Butyl Acetate concentration  by headspace analysis using a 450 varian capillarity GC and and I have been struggling with the reproducibility of the results.I have tried the analysis on split and and splitless mode. When using the split mode, the results are all over the place regardless the split ratio used, (higher concentrations showing smaller peaks etc), although the peak shape is really good. On the other hand, when using the splitless mode the results are…See More
