Adapter on the Purged Packed Inlet” on page 81.)

Be careful! The oven and/or inlet may be hot enough to cause
burns. If the inlet is hot, wear heat-resistant gloves to protect your
hands.
Wear safety glasses to protect your eyes from flying particles
while handling, cutting, or installing glass or fused silica capillary
columns. Use care in handling these columns to prevent puncture
wounds.
Wear clean, lint-free gloves to prevent contamination of parts with
dirt and skin oils.
