Pharmaceutical and personal care products (PPCPs) entering water supplies have been widely studied, but there is little information on the activity of these compounds in swimming pool water. Researchers have applied a PPCP analysis method previously developed for the detection of 32 PPCPs in wastewater to survey indoor swimming pools in the USA.
Mycotoxins are an important group of secondary metabolites produced by fungi that can cause disease in humans and animals. Active in the field of mycotoxin analysis is Rudolf Krska from BOKU, IFA-Tulln in Vienna and in this video he discusses his work investigating the human metabolism of Fusarium mycotoxins and gives his view on the future direction of mycotoxin research.
The lives, careers, and achievements of the 2015 LCGC Award winners - Joseph Jack Kirkland, the winner of the 2015 Lifetime Achievement in Chromatography Award, and Caroline West, the 2015 Emerging Leader in Chromatography - are highlighted here.
I have been at The University of Texas at Arlington for almost 10 years, and I have taught approximately seven different classes in my time here. Yet, the one that I have had the most opportunities to teach, and the most time to reform, is our junior/senior-level Instrumental Analysis (IA) course.
On Monday, February 2, the New York State Attorney General’s office sent letters to four major retailers accusing them of selling fraudulent herbal supplements and demanding that they remove the products from their shelves. To the surprise of many analytical chemists, however, the accusations were based on DNA barcoding technology rather than chromatographic analysis.
A QuEChERS-based ultrahigh-performance liquid chromatography triple quadrupole tandem mass spectrometry (UHPLC–QqQ–MS–MS) method was used to determine pesticides in nutraceutical products from green tea (Camellia sinensis),
A simple and rapid ultrahigh-performance liquid chromatography tandem mass spectrometry (UHPLC–MS–MS) method to identify new psychoactive substances (NPS) in hair has been published.
LCGC Blogger Kevin Schug offers his insights into superficially porous particles (SPPs) versus fully porous particles (FPPs).

This instalment of “Questions of Quality” looks at problems with an operational liquid chromatograph to see if they can be picked up in the performance qualification (PQ) or prevented in the operational qualification (OQ).
Avermectins are a series of 16-membered macrocyclic lactone derivatives that are used extensively in animal and crop protection.

The dioxin family consists of 210 compounds, of which 17 contain the 2,3,7,8 pattern of chlorination. These 2,3,7,8-containing compounds are of extreme concern to human health because of their high level of toxicity. Approximately, 12 of the 209 polychlorinated biphenyls have also been identified as human toxins. For this reason, the US FDA and EU have established strict regulations for the monitoring of food products for human consumption, in particular edible oils. Manual extractions of oils can be a time-consuming procedure often delaying lab turnaround times. By automating the process with the PowerPrep®, food oil samples can be reliably processed with routine 24 h turnaround times.
If you do Gas Chromatography, then you will have undoubtedly conditioned a capillary GC column ready for use after a period of storage or before first use.
I have had enough conversations with experts in the field of high performance liquid chromatography (HPLC) stationary-phase supports to know that there is more to the increased efficiency provided by the use of superficially porous particles (SPP) compared to fully porous particles (FPP) than simply mass transfer effects. Yet, I would argue that this is still one of the biggest misconceptions propagated by some members of the chromatography community.
A review of the 8th International Symposium on Packed Column SFC (SFC 2014), which was held in Basel, Switzerland, on 8–10 October 2014.
LCGC Blogger Tony Taylor asks if we are too scared to properly explore selectivity options in high performance liquid chromatography (HPLC).
