What is the meaning of end capped?
What is the meaning of end capped?
: a display of products placed at the end of an aisle in a store.
What is ODS in HPLC columns?
An ODS column is filled with a packing of octadecylsilyl groups (ODS groups or C18 groups) chemically bonded to a silica gel carrier. ODS columns are used for reverse-phase chromatography. ODS columns find a wide range of applications due to their high theoretical plate number and rapid equilibration.
Is end cap a word?
or end-cap, end cap a shelving unit for store merchandise that is placed at either end of the main shelving unit along an aisle: an endcap displaying some items on sale. the retail space at either end of a strip mall: a bank endcap with a drive-through window.
Why is a C18 column called an ODS column?
It is also abbreviated as C18 column because it contains octadecasilane chains. This means we can fill up a C18 column with a packing of octadecysilyl groups (these are also named as ODS groups or C18 groups) that are chemically bonded to a silica gel carrier. These ODS columns are specifically used for reverse-phase chromatographic techniques.
Which is better C18 or C18 endcapped column?
Polar endcapped C18 phase Alternative selectively compared to conventional C18 phases Compatible with 100% aqueous mobile phases Thermo Scientific Aquasil C18 HPLC Columns provide greater retention than C18 for polar molecules. …from acidic through slightly basic.
What does it mean when a column is called end capping?
This technical article discusses what is meant when a column is referred to as end-capped, and what the function of the end-capping is. To understand end-capping, we need to step back and look at the bonded phase on the HPLC column.
Why is the BDS column called the endcap column?
It is also named as BDS C18 column, and this column is packed with octadecasilane chains. The term BDS stands for Base Deactivated Silica. Therefore, these columns are also named as endcap columns. This column is very important in chromatography because it has its residual silanol groups deactivated by capping.
