Overview

The COSMOSIL 5C18-AR-II chromatographic column is a polymerized C18 reverse phase column. Due to the fact that its stationary phase octadecyl is bound to the surface of the packing silica gel through multi-point bonding, the stationary phase of this chromatographic column will not easily detach due to the presence of acid compared to a single point bonding chromatographic column. This chromatographic column is highly suitable for the analysis of acidic compounds and peptides under acidic mobile phase conditions.

Strong acid resistance
Suitable for acidic compounds and peptides

Acid resistance:

Comparison of decomposition test results of 0.1% trifluoroacetic acid aqueous solution at 60 ° C. The capacity factor (k ') is the naphthalene value when the mobile phase is methanol: water=70:30.

flushing method	Method for removing buffer, salt, and acid from the chromatographic column: Rinse with a mobile phase free of buffer, salt, and acid for 10-15 minutes. Example: When the mobile phase is methanol/phosphate buffer (20mmol/L)=50/50, rinse with methanol/water=50/50 The method of flushing the attached substances in the chromatographic column and the solution when the baseline is unstable When the sample is not protein, rinse with methanol or *. When the sample is protein, use 0.1%C2HF3O2Rinse with 50-70% acetonitrile/water
