The benefits of supported liquid extraction (SLE) in sample cleanup and, in particular, the use of a synthetic SLE sorbent are discussed.

This article examines the various effects of phospholipids in liquid chromatography tandem mass spectrometry (LC–MS-MS) analysis and demonstrates a new phospholipid-removal approach.

When working with complex matrices such as personal care products, sample preparation is perhaps the most difficult step of the analysis process. By utilizing a targeted sample preparation technique, such as ion-exchange SPE, analysis can be significantly improved as compared to less targeted techniques such as liquid-liquid extraction.

The current state of economic affairs is tumultous; as the economy struggles to bounce back, companies across all industries are becoming more creative in finding ways to reduce costs without sacrificing the quality of their goods or services. According to a recent survey conducted by the Society of Forensic Toxicologists (SOFT), 64.5% of forensic labs surveyed are implementing changes, or plan to implement changes, as a result of limited resources.

An update on the sample preparation and LC–MS-MS tools available for allergen detection, as well advantages of those techniques.

Barbiturates are a class of antidepressants whose abuse and addiction by recreational users has become a widespread problem (www.nlm.nih.gov). In our work we strived to streamline the barbiturate screening process to provide a fast, cost-effective, and reproducible method from start to finish for forensic labs who are involved in high-throughput processing.

In pain management analysis, urine is often used as it is a copiously available bodily fluid that can be collected easily and used for analysis.
