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).

Application

• Determination of nifedipine in serum of women in preterm labor by high-performance liquid chromatography with diode array detection.: This study utilized Purospher^® RP-18 endcapped (5 µm) columns in the HPLC analysis of nifedipine levels in serum samples from women in preterm labor. The research demonstrated the effectiveness of the Purospher^® RP-18 columns in achieving high resolution and sensitivity, making it a valuable tool for bioanalytical applications in clinical chemistry (Kowalczuk et al., 2006).
