Loosen the jet with a nut driver.
15 Pull the jet straight out of the detector. Use tweezers, if
necessary.
16 Place the jet in the detector body.
17 Using a nut driver, tighten the jet 1/6 turn past
finger- tight. Do not overtighten.
18 Attach the column to the detector. (See “To Attach a
Capillary Column Adapter on an Adaptable NPD” on
page 266.)
19 Use a cotton swab wetted with solvent to clean the
residue from the inside of the collector and around the
jet. If the collector appears very dirty, replace it with a
new one.
20 Install the bottom metal C- ring, the lower ceramic
insulator, and the top metal C- ring. See Figure 7.
21 Install the collector.
The adaptable NPD jet is longer than the capillary optimized NPD
extended jet and should never be installed in a capillary optimized
detector.
