摘要：

A safe, simple, maintenance-free, formic acid trap was assembled on a gas chromatograph to resolve C-4 through C-18:2 fatty acids for quantitative analysis. The trap was designed with the option to by-pass formic acid for nomal GC use. It had a storage capacity for 80 ml of formic acid, permitting continuous GC operation 24 hr/day. Helium carrier gas saturated with formic acid vapor was directed to both reference and sample GC injection ports. Gas chromatograms showed flat baselines and excellent resolutions, with minor peak tailing and no ghosting.
