Solid phase microextraction (SPME) has experienced rapid development and growth in number of application areas since its inception over 20 years ago. It has had a major impact on sampling and sample preparation practices in chemical analysis, bioanalysis, food...

Analysis of the California list of pesticides, mycotoxins, and cannabinoids in chocolate using liquid chromatography and low-pressure gas chromatography-based platforms.

Journal of separation science

Reyes-Garcés N, Myers C.
PMID: 33908699
J Sep Sci. 2021 Jul;44(13):2564-2576. doi: 10.1002/jssc.202001265. Epub 2021 May 24.

Cannabis legalization has led to the development of a variety of cannabis-infused products with edibles being one of the most popular. The state of California has implemented comprehensive cannabis testing regulations requiring the analysis of cannabinoids (potency) and contaminants,...

Development of a new in-vial standard gas system for calibrating solid-phase microextraction in high-throughput and on-site applications.

Journal of separation science

Gómez-Ríos GA, Reyes-Garcés N, Pawliszyn J.

In this work, an innovative, reproducible, and reusable standard generator vial is presented. The standard generator vial consists of vacuum-pump oil doped with McReynolds probes (benzene, 2-pentanone, pyridine, nitropropane, 1-pentanol, and n-octane) mixed with a polystyrene-divinylbenzene resin without functional...

Evaluation of a multi-fiber exchange solid-phase microextraction system and its application to on-site sampling.

Journal of separation science
