1. Overview
The Model 210D front panel houses the UV detector lamp switch, Rheodyne injection valve, prime/purge
valve, pressure gauge, and the storage
compartment. In the storage compartment
are the LED display for the column
temperature, and the vacuum degas pressure
gauge (shown above). An accessories kit is
included with your 210D. In the kit are two
PEEK finger tight nuts (Alltech part # 32233)
for column connection, a spare 1/16”
stainless steel fitting (Valco part ZN1) and
ferrule (Valco part ZF1S6), a flange fitting
(Upchurch part 203X) and ferrule
(Upchurch part 240X) for the solvent recycle valve, a 20mL priming syringe (Sigma Aldrich part Z248037),
and a 100µL glass injection syringe (SGE part 005300).
