Packing a Column and Performing a Separation with Sephadex® LH-20
This page shows how to perform a separation with a Sephadex LH-20 column from GE Healthcare which are Size Exclusion Chromatography media of polysaccharide network made from cross-linked hydroxypropylated dextran beads.
Residual Analysis Optimized for Static Headspace GC Applications
Static headspace GC (GC-SH) is a technique used to concentrate volatile analytes prior to analysis. It can improve detection of low level volatile analytes and minimizes matrix interference by eliminating the need to inject the sample directly.
Solid Phase Extraction: Normal Phase Methodology
Retention occurs through polar interaction between the sorbent and analytes. Typical sample matrices that can be employed in normal-phase SPE include hydrocarbon or fatty oils diluted in a solvent like hexane, isooctane, chlorinated solvent, THF, diethyl ether, or ethyl acetate.
Handling and Storage Protocol for Synthetic Peptides
One of the most challenging aspects of working with synthetic peptides is determining the best solvent in which to dissolve the peptide. General guidelines for proper storage, handling and dissolving your synthetic peptide are provided.
