High Performance LC
	GPC - Gel Permeation Chromatography Reprogel PS GPC columns are packed with Polystyrol/Divinylbenzene Copolymer packings with 3, 5 or 10 µm particles. Typical theoretical plate numbers/m are : for 3 µm: 110 000/m, for 5 µm: 70 000/m and for 10 µm: 50 000/m. The particles are totally spherical and pressure stable up to 160 bars. Column dimensions are: 300 x 8 resp. 600 x 8 mm and 50 x 8 mm for guards. The optimal flow rate is 1 ml/min.
