End capping in HPLC columns refers to the process of chemically modifying the surface of silica particles to block unreacted silanol groups. This is done to reduce unwanted secondary interactions between the analytes and the stationary phase, enhancing column efficiency and improving peak shape. End-capped columns typically provide better reproducibility and selectivity in separation, making them suitable for a wider range of applications.

What is the difference ods and ods2 HPLC Column?
BDS - Base deactivated Silanol ODS - Octadecyl silane by using the BDS column, residual silanols deacivated and silanol activity reduced, it is end-capped column and it is good for basic compounds. ODS is normal column and high acidic silica, it is not suitable for basic compounds.
What is silanol activity for a HPLC column?
Silanol activity in an HPLC column refers to the presence of silanol groups (Si-OH) on the surface of silica-based stationary phases, which can interact with analytes. These groups can lead to secondary interactions, such as hydrogen bonding and ion exchange, potentially affecting the retention and separation of compounds. High silanol activity can cause peak tailing and reduced resolution, especially for basic compounds. Therefore, columns with modified or end-capped silica are often used to minimize silanol activity and improve performance.

How many columns have the Parthenon?
The Parthenon had a total of 69 columns. There were 46 outer columns and 23 inner columns.
Mechanism of end capping in hplc column?
A column is said to be endcapped when a small silylating agent, such as trimethylchlorosilane, is used to bond residual silanol groups (-OH) on a packing surface. It is most often used with reversed-phase packings and may cut down on undesirable adsorption of basic or ionic compounds.
