Trimethylsilyl reagents (TMS) have been widely used as end-capping reagents for silica-based reversed-phase LC packing. As a new concept, 1,2-bis(dimethylchlorosilyl)ethane, which was bonded to the methyl groups of two trimethylchlorosilane reagents, was thought to function as a denser end-capping reagent than trimethylchlorosilane. In this study,...

I want to thank Alexandra Izydorczak, Troy Wood and  Wilfrido Mojica for sharing their poster Metabolic Profiling of Cancer Biomarkers from Methanol Extracts from Pathology Specimens using LC-MS/MS from ASMS 2023. Although we are not related to this poster, other than receiving it, I found the chromatography and method interesting. The following...

I would like to thank Katherine Nyarko, Kaitlyn Boozer, and C. Michael Greenlief for sharing their paper "Profiling of the Polyphenol Content of Honey from Different Geographical Origins in the United States" Although we are not related to this work, other than receiving it, I found the application particularly...

I would like to thank Hayley Herderschee, Ph.D. (c) for sharing her poster from HPLC 2022. Although we are not related to this poster, other than receiving it, I found the chromatography interesting. The poster is entitled "HPLC- and UHPLC-MS Analysis of Pharmaceutically Relevant Biomacromolecules on the Analytical and...

While reading Lab Manager I came across this article titled, "Is Outsourcing Calibration and Metrology Services Right for You?" by Roark Galloway of Full Spectrum Lab Services from CBRE.• Roark's article speaks about the post-pandemic landscape, laboratory managers are prioritizing operational efficiency. Whether in large or small labs, managing multiple...

Phenyl and biphenyl stationary phases in chromatography are explored.These phases exhibit dipole-dipole interactions, including π-π, CH-π, OH-π, NH-π, halogen-π, and lone pair electron-π interactions.The study focuses on the role of π-π and CH-π interactions in separating different compounds.Dinitrobenzene, trinitrobenzene, and sulfonamides are used to evaluate...

This poster introduces the Chromanik ArmorShell C18 Column and how it compares to other C18 Hybrid HPLC Columns.Trimethylsilyl reagents (TMS) have been commonly used to cap silica-based reversed-phase LC packing. However, difunctional silyl reagents like hexamethyl dichloro trisiloxane have been introduced to reduce residual silanol groups on...
