The gas chromatograph (GC)‐infrared spectroscopy (IR) technique combines the particular separating capacity of GC and the faultlessly with distinguishing capacity of molecular structure of IR ,its detective sensitivity is very high and itis used to separate and identify many kinds of complicated compounds from element speciation analysis ,natural products ,and gasoline . This paper introduces the principle of GC‐IR .Three types of interface techniques ,light pipe technique ,matrix isolation tech‐nique and direct deposition technique are compared .Connection type with other detections and factors influencing sensitivity in interface are also introduced .The improvement and achievement in coupling GC system ,interface ,data processing techniques and its application is reviewed in the present paper .
