May 26, 2025 · The described method provides an alternative screening method using precursor ion scan (PIS) acquisition on a liquid chromatography tandem mass spectrometry (LC-MS/MS) …

Apr 15, 2024 · A simple method for the quantification of low levels of nine nitazene analogs and brorphine in Dried Blood Spots (DBS) was developed and validated. 10 μL of spiked whole …

Whole blood samples were prepared using 96-well LPME and analyzed using LC–MS-MS. By utilizing a microextraction technique, samples could be prepared with minimal waste and …

LC–MS was able to detect additional compounds in RS-3 sample that were not detected using SERS, FT- IR, and DART-TD-MS.

Dec 12, 2023 · We here present a simple quantitative approach for the determination of nine nitazene analogs, namely, clonitazene, etodesnitazene, etonitazene, etonitazepyne, …

In LC/MS, all compounds were detected in both positive and negative modes of electrospray ionization. Characteristic fragment ions were observed in the product ion spectra of …

This research aimed to develop and validate a LC-QTOF-MS method using Targeted MS/MS for 7 forensically relevant nitazene analogs (4’- OH nitazene, 5-methyl etodesnitazene, …

By coupling LC to MS, a powerful analytical tool could be put into operation, but first, one challenge had to be bridged: everything that elutes from the column must enter the MS as a …

Jun 22, 2024 · Presented here are the first IMS and collision cross section (CCS) measurements on a set of fourteen nitazene analogs using a structures for lossless ion manipulations (SLIM) …

In this paper, the UHPLC-MS/MS methods for the simultaneous determination of 26 designer ‘nitazene’ analogs in biological samples was developed and fully validated.
