Table 320-1 Jets and Collectors for the Capillary-Optimized NPD
The adaptable NPD fits packed columns and can be adapted to fit capillary columns.
It is shipped with the capillary column jet and standard collector. You must
change the jet to use packed columns. Instructions appear later in this
chapter.
Table 320-2 Jets and Collectors for the Adaptable NPD
The extended jets, used with the small id collectors, reduce the exposure of
the sample to heated metal and reduce tailing of some very polar components.
