Abstract: The basic knowledge of diluent and the standards, methods and instruments for diluent testing at home and abroad were summarized. The interference of fire site matrix, extraction and preservation of test materials on diluent identification was introduced. It is suggested that the method of chemometrics can be used to identify diluents. Twenty-three kinds of diluents were tested, and the difficulties of diluent test were analyzed. The prospect of diluent testing and identification was put forward.

Key words:  ignitable liquid, paint thinner, identification, fire matrix interference; fire investigation
