Ameritox, Ltd. (Midland, Texas), a U.S. leader in pain prescription urine drug monitoring, announced its addition of an LC-MS-MS method for detecting prescription pain medications.
"We are very pleased to be among the first pain medication monitoring laboratories to invest in this advanced LC-MS-MS multiplexing technology," said Dr. James Bourland, the laboratory director at Ameritox. "By converting two high-volume confirmations from GC-MS to multiplexing LC-MS-MS, Ameritox is able to provide even faster turn-around times as well as the most accurate and reliable analytical results to physician practices, which helps them provide better patient care."

Study Explores Thin-Film Extraction of Biogenic Amines via HPLC-MS/MS
March 27th 2025Scientists from Tabriz University and the University of Tabriz explored cellulose acetate-UiO-66-COOH as an affordable coating sorbent for thin film extraction of biogenic amines from cheese and alcohol-free beverages using HPLC-MS/MS.
Multi-Step Preparative LC–MS Workflow for Peptide Purification
March 21st 2025This article introduces a multi-step preparative purification workflow for synthetic peptides using liquid chromatography–mass spectrometry (LC–MS). The process involves optimizing separation conditions, scaling-up, fractionating, and confirming purity and recovery, using a single LC–MS system. High purity and recovery rates for synthetic peptides such as parathormone (PTH) are achieved. The method allows efficient purification and accurate confirmation of peptide synthesis and is suitable for handling complex preparative purification tasks.
