A two-stage process involving a thermo-evaporative technique was employed to coat glass capillary columns with polar phases. Silanox 101 and a small amount of liquid phas: were introduced in the first stage: additional phase was introduced in the second stage. The theoretical plate efficiency for Se
## 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 5β30%. The symmetry continued to improve, alth
