Increasing Speed of UHPLC-MS Analysis of Vitamin D for Research Use

submitted by: Chrom Solutions

Sarah Fair presents her scientific poster about removing manual pipetting from the analysis of vitamin D metabolites, testosterone and cortisol using the accuracy and precision of the Thermo Scientific Platemate Pipetting Workstation. Using the automated system offered significant time savings and passed all acceptance criteria for the compounds tested.

Detection of rHuEPOs in Horse Plasma Samples at Low pgmL Levels using High-Resolution MS Strategies

submitted by: Chrom Solutions

Madalina Oppermann presents her scientific poster about improving the detection and quantification limits for the analysis of recombinant human erythropoietin (rHuEPOs) in horse plasma for doping control using the Thermo Scientific Q Exactive mass spectrometer. The results show the promise of nano-LC-MS/MS analysis on a high-resolution Orbitrap mass analyzer confirm and quatify the rHuEPO target peptides in a single analytical run, with high specificity, sensitivity and resolution.

High Resolution Screening and Quantitative Analysis of Antibiotics in Drinking Water

submitted by: Chrom Solutions

Jonathan Beck discusses online sample pre-concentration and extraction of water samples followed by analysis with high-resolution, accurate mass (HR/AM) detection, quantitation and confirmation. Screening, confirmation and quantitation of antibiotics in drinking water was done in the same analytical run with the Thermo Scientific Orbitrap platform.

Human Cell-Free Expression System Generates Stable-Isotope-Labeled Protein Standards for Mass Spec

submitted by: Chrom Solutions

John Rogers presents his scientific poster about human cell-free expression system for the production of stable-isotope-labeled (heavy) proteins using HeLa cell lysates. Six different stable-isotope-labeled proteins were produced. Isotope incorporation efficiency of greater than 95% was observed for IVT reactions.

EPA 525.2 for the Analysis of Organic Contaminants in Water (Webinar)

submitted by: Chrom Solutions
This webinar reviews EPA Method 525.2 (SPE-GC-MS method) for the analysis of organic contaminants in drinking water. In order to achieve the low detection limits, water samples are extracted and concentrated prior to injection into the GC-MS. Automated systems remove the laborious, less accurate steps of vacuum systems and at the same time, save solvent and cost less overall. Speakers: Beau Sullivan (Santa Clara Valley Water District), Richard Jack (Thermo Fisher Scientific). Visit...
