The 2-Minute Rule for columns used in HPLC
The focus of polynuclear aromatic hydrocarbons (PAH) in soil is set by 1st extracting the PAHs with methylene chloride. The extract is diluted, if necessary, and the PAHs separated by HPLC employing a UV/Vis or fluorescence detector. Calibration is accomplished working with one or more external expectations. In an average analysis a 2.013-g sample
