You might get best&reliable results with chromatography. Sensors (called detectors) in LC are light-based - you detect absorption at various wavelengths related to time a material (each fraction) is capable to pass a separating colon.


P.S. If you'll continue to use complete colored and bolded text in your messages, I'm going to ignore them !
