Thin Layer Chromatography
Sorbent Technologies Inc Cellulose 300 TLC Plates, w/UV254, polyester backed, 100um, 20x20cm, 25/pk
Cellulose 300 with UV254, polyester backed TLC plates. The coating thickness is 100um and dimensions are 20x20cm. There are 25 plates per pack. Applications include: partition chromatography of polar substances such as amino acids, carboxylic acids or carbohydrates. Cellulose is especially used for partition chromatographic separations of polar substances such as amino acids and other carboxylic acids or carbohydrates. Compared to paper chromatography (PC) thin layer chromatography, cellulose offers shorter migration times and more concentrated substance spots resulting in a higher detection sensitivity. TLC plates (CEL 300) are coated with native, fibrous cellulose.
