A Secret Weapon For how HPLC works
The focus of polynuclear aromatic hydrocarbons (PAH) in soil is set by initial extracting the PAHs with methylene chloride. The extract is diluted, if necessary, plus the PAHs divided by HPLC using a UV/Vis or fluorescence detector. Calibration is reached utilizing a number of external requirements. In a standard Examination a 2.013-g sample of dri
