Description

General description

HPLC cartridge

Purospher^® RP-18 endcapped is a versatile high-purity HPLC column producing excellent peak shapes. The excellent balance of Purospher<TMSYMBOL></TMSYMBOL> RP-18 endcapped in the sum of its chromatographic properties is the key to better separations of complex samples with simpler, neutral eluents. The good chemical stability of Purospher<TMSYMBOL></TMSYMBOL> RP-18 endcapped enables the use of mobile phase conditions at pH 8 for a long period of time. The connection to the HPLC system is being accomplished by use of the manu-CART NT cartrige holder (1.51486).
