Controlled substances such as marijuana, cocaine, heroin and methamphetamines are commonly seized by law enforcement officials and routinely analyzed by forensic laboratories. More recently, synthetic drugs such as bath salts and cannabinoids, as well as naturally occurring “herbal remedies” and hallucinogenic mushrooms, have gained popularity as chemical stimulants and opiate substitutes. This study focuses on the comprehensive profiling of complex botanicals obtained from drug seizures.
Overcoming the Challenges of Analysing Ionic Polar Pesticides in FoodPoster
Here, the novel application of the Waters’ Torus DEA column is presented, showing the improved performance of a UPLC-MS/MS method for the underivatised
analysis of glyphosate and a selection of other anionic pesticides.
A New Tool for the Automated Sample Preparation of Whole Blood Samples by LC-MS using a Commercial AutosamplerPoster
Automated sample preparation reduces the costs per sample and minimizes sample handling errors. Usually expensive and highly specialized pipetting robots are used. However, most of these systems are not designed with a direct interface for LC-MS applications. In addition common pipetting systems are not optimized for smaller scale sample series. Here we present a new tool for liquid handling of whole blood samples and direct sample injection.READ MORE
