The American Chemical Society (ACS) released its new strategic plan, which reinforces the organization’s mission to improve lives through the power of chemistry.

In this podcast, Daniel DeBord, CTO of MOBILion Systems, describes a new high resolution mass spectrometry approach that promises to increase speed and sensitivity in omics applications. MOBILion recently introduced the PAMAF mode of operation, which stands for parallel accumulation with mobility aligned fragmentation. It substantially increases the fraction of ions used for mass spectrometry analysis by replacing the functionality of the quadrupole with high resolution ion mobility. Listen to learn more about this exciting new development.

Can a protein involved in delivering Vitamin D to target tissues have an altered serum profile in psoriasis patients with cardiovascular disease? Researchers used liquid chromatography (LC) to help find out.

Peter Pellegrinelli, Applications Specialist at Advanced Materials Technology (AMT) explains the complexity of oligonucleotide separations due to the unique chemical properties of these molecules. Issues such as varying length, sequence complexity, and hydrophilic-hydrophobic characteristics make efficient separations difficult. Separation scientists are addressing these challenges by modifying mobile phase compositions, using varying ion-pairing reagents, and exploring alternative separation modes like HILIC and ion-exchange chromatography. Due to these complexities, AMT has introduced the HALO® OLIGO column, which offers high-resolution, fast separations through its innovative Fused-Core® technology and high pH stability. Alongside explaining the new column, Peter looks to the future of these separations and what is next to come.

LCGC International spoke to Michelle Klein from the Faculty of Chemistry of the University of Duisburg-Essen (Essen, Germany) about how, by using the green analytical chemistry tool Analytical GREEnness (AGREE) and the white analytical chemistry (WAC) framework, her team was able to conduct a comparative analysis of gas chromatography-tandem mass spectrometry (GC–MS/MS), liquid chromatography-tandem mass spectrometry (LC–MS/MS), and the yeast-cell-based reporter gene assay (A-YES).

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.
