The operational principle and the specifications of a portable photoiorization gas chromatograph are described.The chromatograph is composed of two injectors, two columns and one photoionization detector. It has the advantages of wide linear dynamic range, high sensitivity and light weight. The instrument can be used for analyzing trace gases or Vapours in enviromental air and detecting air pollution in working places. Examples of applications are presented.
