function
11. Injector port seals, liner, emitter, collector, nozzle, all can
be easily replaced by sing hand
12. Packed column, capillary injector, TCD, FID can be easy removed
just by a wrench, convenient maintenance
13. Unique high temperature resistant quartz design Nozzle, good
inertia, proper rotary seal
14. Unique capillary positioning system, to keep stability of the
column installation and constant burning rate
