Answer:The fixed tapered needle is 42 mm long and changes from 23 gauge to 26s gauge, with a cone point.
Answer:No. The recommended GC injection volume is 1–8 µL.
Answer:Yes. A compatible replacement PTFE-tipped plunger is available separately.
The Agilent Gold Standard gas-tight syringe supports reproducible liquid injection into compatible gas chromatography autosamplers. The 10 µL barrel uses a fixed 42 mm tapered needle with a 23-to-26s gauge profile and cone point, together with a PTFE-tipped plunger. The PTFE seal helps maintain a tight plunger-to-barrel interface during repeated aspiration and delivery. A 1–8 µL injection range is recommended for this syringe configuration, allowing headroom within the nominal barrel capacity. Before an analytical sequence, check needle straightness, plunger movement, sample uptake and injection reproducibility. Rinse with a suitable solvent after use to reduce carryover; avoid forcing a plunger through deposits or touching the needle tip. A worn PTFE-tipped plunger can be replaced separately without substituting a different syringe-needle geometry.
