LCGC Blog: Column Overload in Gas Chromatography with Vacuum Ultraviolet Detection
Column overload is a very commonly encountered issue in GC for beginners. Changes in peak symmetry, generally observed as peak fronting, can be subtle in the sharp peaks generated by GC, but the result can be significant shifts in retention times, loss of resolution, and error in peak integration. LCGC Blogger Kevin Schug explains more. |

Analyzing Persistent and Emerging Contaminants in Food
Preventing environmental contaminants from getting in to the food chain is of paramount importance to us all. Yelena Sapozhnikova, a Research Chemist at the Agricultural Research Service, United States Department of Agriculture (USDA) in Wyndmoor, PA, USA, spoke to LCGC about her research into the development and evaluation of analytical methods for persistent and emerging organic chemical contaminants in food samples. |

Searching for Salt in Historical Buildings
A team of scientists has analyzed and evaluated the impact of salt weathering on an historical house. Combining ion chromatography (IC), chemometrics, and thermodynamic chemical modelling to investigate the degradation of building materials — a natural and irreversible process — to understand the causes behind the degradation and implement preventative measures. |

TSKgel Amide-80 for UHPLC |
ACE UHPLC/HPLC Method Development Kits |
The µDAWN™ is the world’s first multi-angle light scattering (MALS) detector that can be coupled to any UHPLC system in order to determine absolute molecular weights and sizes of polymers, peptides, and proteins.

TSKgel Amide-80 is now available in 2 micron particle size. For years, TSKgel Amide-80 columns are used successfully for HILIC separations of polar compounds such as saccharides, glycans, oligosaccharides, or peptides. The amide chemistry is particularly popular for glycosylation analysis of proteins. The new small particle size columns deliver higher resolution and peak capacity and are ideally suited for UHPLC and UHPLC-MS.
