## Abstract The use of ammonia as a carrier gas for the chromatography of aliphatic and aromatic amines has been investigated. As compared to nitrogen, ammonia gave drastically improved peak symmetry and lower capacity factors (__k__′) for primary and secondary amines on polar (Polyethylene glycol)
## Abstract A mixture of ammonia and helium was used as a carrier gas for capillary gas chromatographic analysis of aliphatic amines and dichlorophenols. The peak symmetry for aliphatic amines was drastically improved when the percentage of ammonia was 5–30%. The symmetry continued to improve, alth
