HPLC COLUMNS BY USP L-CODE Technical Note <strong>CS18</strong><br />
The United States Pharmacopeia (USP) maintains a list of codes to specify generic GC or HPLC stationary phases. The phase<br />
definitions are broad, and many columns fit into the more popular categories. Columns within a category will have subtle to not-sosubtle<br />
differences in performance. For instance, a sub-2µm double endcapped C18 on ultra-pure type B spherical silica and a 10<br />
µm non-endcapped C18 on original type A irregular silica are both L1 phases. They will not produce the same results.<br />
The following list provides an overview of the columns that CSI can provide for each USP code. This is not an exhaustive list.<br />
These are columns recommended for new method development, along with some columns that we have recently gained access to<br />
for older methods.<br />
USP L-classes are very broad. It is still vital to match your column to your analyte and analysis conditions.<br />
For any questions please contact the CSI Technical Support Staff, who are always happy to discuss<br />
your analyte and mobile phase to help select the best match from our extensive line of columns.<br />
