Figure 6: Adaptor and FID Weldment
5.2.3 Install the adaptor for FID as follows.
• For capillary FID weldment (Figure 6):
- Place the adaptor for the capillary FID and a 0.8 mm ferrule (cat.# 27067) over the transition tubing. Wipe the end of the
transition tubing clean with a tissue dampened with isopropanol to remove fingerprints and ferrule pieces before inserting
it into the FID.
- Thread the adaptor for the capillary FID and the transition tubing into the FID detector base.
- Insert the transition tubing all the way into the detector jet until it stops, then withdraw it 1-2 mm. Tighten the adaptor until
finger tight. Use a wrench to tighten the adaptor an additional ¼ turn.
• Note: This methanizer has not been designed to operate with packed columns in Shimadzu GCs as there was no universal
option. We gain better results using micropacked columns like the Shincarbon ST installed in the capillary fitting.
