Targeted and Untargeted Forensic Screening Methods by Gas Chromatography-Mass Spectrometry for Anti-Doping and Forensic Toxicological Purposes

This application note shows how to achieve higher recoveries for commercially available MAbs using 15 % isopropanol as modifier in HIC mode.

mAb Method Using Isopropanol in HIC

Shodex HILICpak VT-50 is suitable for the analysis of phosphorous-containing amino acids herbicids including glyphosate, glufosinate and their metabolites using ESI-MS detection.

Shodex HILICpak VT-50 2D: A HILIC + Anion Exchange HPLC Column for Polar Pesticide Analysis including Glyphosate

Antibody molecular weight analysis can now be easily performed on the Shodex PROTEIN LW-803.

A New Silica-based Aqueous SEC Column for Analysis of Antibody Proteins

Strata-X PRO was chosen to extract a panel of acids, neutrals, and bases from plasma. This simple method eliminates time-consuming method development and recovery for extremely polar analytes.

Extraction of Acids, Neutrals, and Bases from Plasma

Using Strata-X PRO to extract barbiturates from serum saves time by reducing the method to 3 quick and easy steps. In addition, the matrix is more effectively clean-up vs protein precipitation.

Barbiturates from Serum Using Strata-X PRO Solid-Phase Extraction

Strata-X PRO consists of a new type of polymeric SPE sorbent combined with matrix removal technology to revolutionize sample extractions and matrix clean-up by eliminates the conditioning and equilibration steps.
