06 Nov A Simple and Sensitive LC-MS/MS Method For Quantification of 7α-hydroxy-4-cholesten-3-one (C4) in Human Serum
I would like to thank Aiping Zhu, Tian-Sheng Lu, and Shuyu Hou from Medpace Bioanalytical Laboratories, for sharing their poster from ASMS 2024. "A Simple and Sensitive LC-MS/MS Method for Quantification of 7α-hydroxy-4-cholesten-3-one (C4) in Human Serum." I found the application particularly interesting as it shows how Pentafluorophenyl (PFP) HPLC...
05 Nov Perfusion Fermentation Sets A Path To Democratize Biomanufacturing.
I had the chance to attend INTERPHEX Global at the Javits Center back in April and in my quest to find new fluidic applications, I discovered Sunflower Therapeutics, in which solutions include: The first microbial perfusion fermentation system designed and built for continuous protein production,...
16 Oct Assessing Antidepressant Pharmaceuticals in the Environment through the Development of a Multidimensional Liquid Chromatography-Ion Mobility Spectrometry-Mass Spectrometry Library
I would like to thank Emily Crawford, et.al from the University of North Carolina Chapel Hill for sharing their poster from ASMS 2024 titled "Assessing Antidepressant Pharmaceuticals in the Environment through the Development of a Multidimensional Liquid Chromatography-Ion Mobility Spectrometry-Mass Spectrometry Library." Although we are...
16 Oct Ultra-Sensitive LC-MRM Based Method for Rapid and High-Throughput Screening of Sugar Phosphate Isomers in Cell Culture
I’d like to thank Dan Su and Fatemeh Mousavi, Ph.D. of HD Biosciences Co., Ltd for sharing their poster from ASMS 2024: "Ultra-Sensitive LC-MRM Based Method for Rapid and High-Throughput Screening of Sugar Phosphate Isomers in Cell Culture." While we aren't directly involved, I found...
20 Jun Consideration Of π-π and CH-π Interactions as Dipole-Dipole Interactions in Biphenyl Stationary Phases
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...
20 Jun Novel End-Capping Method With Silyl-Reagent Including Ethylene Chain
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...
17 Nov Eastern Analytical Symposium 2022. Brief Product Overview.
PDF: Effect of Organic Solvent in Mobile Phase on Dipole Interaction Using BiphenylSome more of the EAS 2022. It was nice to connect with everyone and learn a lot too. ...
