Application Notes: General

Magic mushrooms, once taboo, have recently experienced a renaissance. This new awakening is partially due to new findings that indicate the effects of psilocybin, and its dephosphorylated cousin psilocin may produce long lasting results for patients who might be struggling with anxiety, depression, alcohol and drug abuse, and post-traumatic stress disorder. Hamilton Company has developed a methodology for the isolation and identification of 5 common psychedelic compounds used in the potential treatment of disease. The PRP-1 HPLC column resin remains stable in the harsh alkaline conditions ideal for better separations.

Top quality materials and skilled workmanship ensure Hamilton syringes consistently deliver the highest possible performance for reliable analyses. With proper care and handling, Hamilton syringes provide unsurpassed performance year after year. This guide covers daily syringe use along with safety information and troubleshooting tips.

The G protein-coupled receptors (GPCR) are found throughout the entire body and have shown significance in the development of new therapeutic treatments. Isolation of seven classic GRPC peptides initiating in the GI tract highlights the benefits of using the polymer-based PRP-3, a reversed-phase resin. The covalent bonds found in the PRP-3 exhibit advantageous interactions between the biological π bonds found in the peptides and the available aromatic benzyl rings of the resin.

This application note demonstrates how THF mobile phases can be replaced to implement greener, safer, and less toxic SEC methods for polymer characterization.

This application note highlights the benefits of the LipiFiltr® cartridge for multi-class, multi-residue pesticide analysis in complex, high-fat samples.

Agilent and Scitara are collaborating not only to increase the efficiency of laboratory processes, but to enable customers to leverage the value of the data for various stakeholders. This paper will present an ecosystem designed to support enterprises in accelerating data workflows and improving data availability for researchers, lab analysts, and data scientists.

This study demonstrates high-throughput analysis of BTEX compounds from several matrices (air, water and soil). Detection limits in the single-digit part-per-billion concentration range (by volume) are readily achievable within seconds using SIFT-MS because sample analysis is achieved without chromatography, pre-concentration, or drying. We also present a calibration approach that enables speciation of ethylbenzene from the xylenes in real-time.

This application note summarizes key SIFT-MS results presented in a peer reviewed article entitled “Unreported VOC Emissions from Road Transport Including from Electric Vehicles.” Learn how the Wolfson Atmospheric Chemistry Laboratory at the University of York used SIFT-MS for VOC analysis in its platform to experimentally verify that motor vehicle screen wash is a significant unreported source of VOC emissions (especially for ethanol and methanol).

Method detection limits (MDLs) have been determined for the newly regulated HON (Hazardous Organic NESHAP (National Emission Standards for Hazardous Air Pollutants)) compounds, which validate selected ion flow tube mass spectrometry (SIFT-MS) as an effective solution for measuring these toxic volatile organic compounds (VOCs) and other environmental pollutants in ambient air, whether at the fenceline or in a mobile setting. SIFT-MS offers unparalleled speed, sensitivity and ease of use for environmental monitoring applications.
