What is Quantitative analysis of lipids on copper(II) sulphate-impregnated chromarods about?
Impregnation of Chromarods with copper(I1) sulphate was found to remove the irregularities observed with the Chromarod/flame-ionization detection system (Iatroscan) in quantitative analysis. Of the operating variables, the scan speed affected the response most. At a scan speed of 4.17 mm/set, quantitative analysis of eleven classes of lipids was achieved with Chromarods impregnated with 5% copper(I1) sulphate solution. Under the conditions described, various compounds gave uniform responses so that response factors were not necessary except for phospholipids and cholesterol. It appears that with copper(I1) sulphate-impregnated silica gel, the detector behaves similarly to a hydrogen atmosphere flame-ionization detector, with the result that the response is a function of mass and not of the structure of the compounds being analysed. Impregnation with copper(I1) sulphate also improves baseline stability, minimizes rod to rod variations and makes the solvent front clearly visible.
