Careers. These differing goals also bring about some other difference between the two techniques: in preparative LC, as the goal is to purify and collect your compound or molecule fraction, collection is required, but in analytical LC, as the goal is qualitative and quantitative analysis, the compounds (and the rest of the sample) are simply diverted to waste or to a destructive detector such as a mass spectrometer orcharged aerosol detector. By characterization using LC-MS/MS analysis, all components of a series of PEs were elucidated to be the 12-deoxy-16-hydroxyphorbol esters composed of isomeric form of dicarboxylic groups with same m/z value of 380. A more recent analogy of the differences came apparent to me while my wife and I were making pumpkin soup; her approach is much more preparative, mine more analytical, I have to say. With this semi-preparative HPLC, system parameters for upscaling can be determined easily and economically. Alternatively, you can accomplished preparative and semipreparative chromatography by using a short inner diameter and small size particle (5 micras) by passing a very small flow rate (about 0.05 ml/min) mobile phases with very low viscosity (hexane for example) in the aim of keeping a very low backpressure and saving solvents.In addition, the most important difference between preparative/semipreparative and analytical HPLC is the purpose.
