HPLC columns Fundamentals Explained
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, along with the PAHs divided by HPLC utilizing a UV/Vis or fluorescence detector. Calibration is realized using a number of external standards. In a typical analysis a two.013-g sample of dried
