ODS and BDS are two columns used for reverse-phase chromatography. The key difference between ODS and BDS column is that ODS column contains free OH functional groups, whereas BDS column contains deactivated OH groups. Moreover, ODS columns have high peak tailing while BDS columns are designed to reduce peak tailing.

Based on the available information on the sample and purpose of analysis HPLC methods are classified into the following four basic modes : Microbore HPLC. Analytical HPLC. Semipreparative HPLC.

High-performance liquid chromatography (HPLC), formerly referred to as high-pressure liquid chromatography, is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture....High-performance liquid chromatography.

Hypersil BDS columns are a good choice for QA/QC labs as a robust general purpose column in applications where reproducibility and long column lifetimes are required. Hypersil BDS C18 columns are applicable to a wide range of analytes including acids, bases and neutrals as shown, and are popular in methods worldwide.

Main High-Performance Liquid Chromatography (HPLC) Components. The HPLC system mainly consists of an infusion pump, a sampler, a chromatographic column, a detector, and a data recording and processing device. Among them, the infusion pump, the chromatographic column, and the detector are key components.

Column chromatography can be classified into four classes: adsorption column chromatography, partition column chromatography, gel column chromatography and ion-exchange column chromatography.

The AQ type C18 column, such the ODS-B, has an end-capping that reduces phase collapse greatly, so it can be run in 100% water if needed. The ODS-A column has a more typical hydrophobic end-capping.
