Chemical Analysis And Instrument Analysis Method Application In Causes Of Fire Investgation

Investigating in conflagration cause is one of the important jobs that law gives tothe fire department.It plays a very important part in disaster alleviation , precautionsagainst calamities and the guarantee of the safty of the property of the country andcitizens and the life of the citizens. The purpose of the investigating in conflagrationcause is to investigate and find out the cause of the conflagration. Sum up experienceand lessons in fire control job , bring forward the countermeasure taking precautionsagainst, cut down or avoid the same kind conflagration accident repetition tohappen.Therefore the investication in conflagration cause requests very objective,accurate , legal and non-mistake working. Only in this way can we Sum up experienceand lessons to avoid the same kind conflagration accident repetition to happen andCut down damage. To gain the evidence of affirming the conflagration cause, tovarying degrees various science method has got application in the process ofconflagration cause investigation, among which chemical analysis method has gotbroad application. And have got fairly good effect,especially in the process ofaffirming the conflagration cause and deciding the conflagration character. This paperestablished the use of acid-base titration, gas chromatography, UV and TLC of thefour detection methods and through setting experimental procedure, Selecting theanalysis conditions, Analysis of the Affecting Factors and other means to choose thebest way to experiment. Using that fuor analytical methods, especially the latterthree methods to analysis the fire evidence at the same time, we could exclude theimpact of the burning of other material, enhance the reliability and accuracy andprovide exact and adequate scientific basis for the causes of the fire.
