Determination of Phenolic Compounds in Virgin Olive Oil Using Comprehensive 2D-LC
June 1st 2014This application note demonstrates how comprehensive 2D-LC can be used to resolve the complex mixture of hydrophilic phenols found in virgin olive oil and investigates differences in the phenol composition of several olive oils.
High Resolution LC–MS Analysis of Reduced IgG1 Monoclonal Antibody Fragments Using HALO Protein C4
June 1st 2014A new fused-core particle designed specifically for the separation of proteins and monoclonal antibodies with 3.4 ?m particle size and a thin 0.2 ?m porous shell demonstrates high resolution of the heavy and light chain fragments of IgG1.
Molecular Weight Determination of Unfractionated Heparin
February 1st 2014Heparin is a polydisperse, heterogeneous polysaccharide derived from animal tissue. Heparin has been used as an anticoagulant for over 60 years and one of the fundamental parameters for characterizing unfractionated heparin (UFH) is its molecular weight (MW) and MW distribution.
Hexavalent Chromium Determination Hamilton PRP-X100 Anion Exchange HPLC Column
February 1st 2014Chromium (Cr) is a metal with an interesting relationship to the environment. Whereas trivalent chromium (Cr(III)) is an essential nutrient, hexavalent chromium (Cr(VI)) is a poison to humans and aquatic life and poses serious environmental and ecological threats.
