Analysis of Intact N-Glycans by HPAEC-PAD-MS

When it comes to water analysis, it can be challenging for labs to keep up with ever-changing testing regulations while also executing time-efficient, accurate, and risk-mitigating workflows. To ensure the safety of our water, there are a host of national and international regulators such as the US Environmental Protection Agency (EPA), World Health Organization (WHO), and the European Union (EU) that demand stringent testing methods for drinking water and wastewater. Those methods often call for fast implementation and lengthy processes, as well as high sensitivity and reliable instrumentation. This paper explains how your ICP-MS, ICP-OES, and LC-MS-MS workflows can be optimized for compliance with the latest requirements for water testing set by regulations like US EPA methods 200.8, 6010, 6020, and 537.1, along with ISO 17294-2. It will discuss the challenges faced by regulatory labs to meet requirements and present field-proven tips and tricks for simplified implementation and maximized uptime.

Hamilton has produced a series of reference guides to assist science professionals in finding the best-suited products and configurations for their applications. The Syringe and Needle Reference Guide provides detailed information on Hamilton Company’s full portfolio of syringes and needles. Everything from cleaning and preventative maintenance to individual part numbers are available for review. It also includes selection charts to help you choose between syringe terminations like cemented needles and luer tips.

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.
