Purospher® STAR RP-18e liquid chromatography column

The Purospher STAR RP-18 capped 5 µ m HPLC column is designed for general applications and can separate alkaline, neutral, and metal chelating compounds using a simple mobile phase and excellent peak symmetry. They are based on ultra pure fully porous silica particles (type B). These columns provide excellent stability over a wide temperature range, from pH 1.5 to 10.5, and are suitable for up to 100% aqueous mobile phase. Based on these characteristics, Purospher^®The STAR RP-18 capped 5 µ m HPLC column provides maximum flexibility for optimal chromatographic conditions for various separation operations, including reverse phase separation. Purospher^®STAR RP-18 封端5 µm Hibar^®RT 250-4.6 is a ready to use stainless steel chromatography column suitable for connecting to any HPLC system. The size of the chromatographic column is 250 mm long x 4.6 mm inner diameter, which is the choice for high-resolution separation of complex samples by HPLC. The recommended protective pillar is Purospher^®STAR RP-18 封端 (5 µm) LiChroCART^™4-4 Product Code 1.50250.0001. For direct connection to Hibar^®RT column, suitable for 4-4 LiChroCART^™Pre column bracket for columns, product number 1.51487.0001. Product 1.51456.1003 is a validation kit containing 3 Purosphers from 3 different substrate batches^®STAR RP-18 封端 3 µm Hibar^®RT 250-4.6 HPLC column.
