Analysis of xylazine, opioids, and other common adulterants in blood and urine by SPE and LC-MS/MS
In this application note, UCT, Inc. outlines a method for simultaneously analyzing fentanyl, its analogs, xylazine, and other common adulterants using solid-phase extraction (SPE) and LC-MS/MS. Xylazine, a veterinary sedative, is increasingly used as an adulterant, particularly in fentanyl-containing substances. This combination, known as 'Tranq', poses serious risks, including unconsciousness and heightened addiction, potentially leading to fatal overdoses.
Simultaneous analysis of 19 novel synthetic cannabinoids in urine using SPE and LC-MS/MS
This application note outlines a solid-phase extraction (SPE) and LC-MS/MS method for the analysis of 19 synthetic cannabinoids in urine. These specific compounds were selected based on positivity rates from several key testing labs in the area. The use of UCT’s Styre Screen® HLD highly crosslinked polymeric SPE sorbent ensures efficient extraction of the synthetic cannabinoids while removing undesired matrix components and yielding clean extracts
Determination of Anabolic Steroids in Horse Urine by SPE and LC-MS/MS
Anabolic steroids are used illegally in horse racing to enhance performance. The compounds are excreted in urine either as glucuronide or sulfated conjugate. To test for steroids in horse urine samples undergo an enzymatic deconjugation to release the parent compounds before extraction. Working with horse urine matrix is challenging and generally unpleasant.
Extraction of Synthetic and Naturally Occurring Cannabinoids in Urine Using SPE and LC-MS/MS
Synthetic cannabinoids is the term given to a family of compounds which produce the same effects of marijuana. It is becoming more and more important for labs to develop new methods for testing for these compounds and staying ahead of the growing market. This application note describes a method which can test a sample for synthetic cannabinoids as well as natural cannabinoids simultaneously.
