SACHEM (Austin, Texas) has launched a new HPLC e-Learning program.
SACHEM (Austin, Texas) has launched a new HPLC e-Learning program. The 10-minute simulation-based program enables users to gain a deeper understanding of 2-D HPLC using displacement chromatography. In the first dimension one uses displacement chromatography to concentrate low abundance materials in discrete transition zones within the displacement train. This first step removes 95% of main component interference without affinity resins or prior knowledge of component identity. The second chromatography step is then used to analyze these enriched samples.
