includes a C8 and a cyano bonded phase, and bare
silica. Each of the bonded phases is endcapped.
To ensure the same high quality and reliability as
offered by all other Restek HPLC columns, we
established demanding quality control procedures
to ensure each column performs as expected.
Figure 3 is an example analysis of the test mix we
use to individually quality check every Pinnacle™
DB column.
The Pinnacle™ DB line is available in a wide range
of column dimensions, from 1mm narrow bore
columns through 50mm preparative-scale columns.
Please call our Technical Service Team for addition-
al information about this new column line, or call
our Customer Service representatives to place an
order.
