摘要（英）：

The invention relates to a method for detecting MOCA contents by using GC-MS and application thereof, specifically to application of GC-MS to detection of the MOCA contents of polyurethane adhesives and polyurethane rubber, belonging to the field of detection technology for MOCA contents. The method for detecting MOCA contents by using GC-MS in the invention comprises the following steps: preparation of a standard working solution; analysis of the standard working solution and a to-be-test solution; drawing of a standard work curve and calculation of results; etc. The GC-MS detection method for MOCA contents in the invention is rapid, convenient and accurate, and quantification via an external standard method is realized. The method realizes high-volume, accurate and rapid detection of MOCA contents of polyurethane adhesive and polyurethane rubber samples and is used for evaluating the level of product quality; thus, the method can be used for controlling the quality of polyurethane products and is of great significance to safeguarding of human health and promotion of industry progress.
