The preferred HPLC detectors take advantage of an analyte’s UV/Vis absorption spectrum. These detectors range from easy designs, in which the analytical wavelength is chosen applying appropriate filters, to your modified spectrophotometer by which the sample compartment features a circulation cell.
The analysis is intricate with the advanced matrix of serum samples. A sound-section extraction followed by an HPLC analysis employing a fluorescence detector gives the mandatory selectivity and detection limits.
C. Food stuff and Taste Analysis: Chiral columns are utilized to analyze and differentiate enantiomers in food stuff and flavor compounds, making certain the quality and authenticity of food products.
