Preparative low pressure liquid chromatography the specialist book to combine preparative hplc and production scale separations this monograph closes a sorely felt gap between preparative hplc and production scale separations precisely in this broad area of separation science there is a real need that is far greater than generally assumed very many laboratories require straightforward yet highly versatile powerful and above all economical i e low cost separation systems the . The chromatographic methods that have traditionally been used by organic chemists thin layer chromatography tlc low pressure open column and flash chromatography are supplemented with preparative lc major differences between preparative and analytical lc are column dimensions mobile phase flow rates and sample injection masses and volumes preparative column diameters often go from 46 mm to over 50 mm with lengths of 50 250 mm these large columns can require mobile phase flow .
