Method for detecting release amount of olefines compound in mattress

The invention relates to a method for detecting release amount of an olefines compound in mattress. The method comprises the following steps: a) a sample is processed in an environment climate cabin; b) using Tenax-TA adsorption pipes for sampling, after sampling is completed, performing thermal desorption-GC/FID analysis; c) setting the correlation index in an Unity2 type heat-removal instrument; d) using a DB-1 chromatographic column for processing the sample; e)preparing a mixing standard solution; f) taking the mixing solution for dilution to obtain the mixing standard with different concentration, respectively taking 1 mumL of the mixing standard solution with different concentration and injecting 6 aged Tenax-TA adsorption pipes, putting the pipes in the heat-removal instrument, performing the GC/FID analysis, taking the object content as abscissa and peak area ratio as ordinate, drafting a standard curve; and g) obtaining an equation of linear regression, correlation coefficient and detection limit of
