Embodiment 1

[0026] Taking seat foam, a typical material in the car, as an example, the steps to prepare its typical odor simulating gas are as follows:

[0027] 1. Select seat foam samples that have been offline for 7-14 days, and pretreat them for 24 hours before the experiment in an environment with 23°C, humidity 50%RH, and no volatile solvents and odors.

[0028] 2. Take 5g of sample, and use scissors to cut out the sample particles with a mass range of 10-25mg. Put it into a 40ml sample bottle, set the purge temperature to 25°C, the purge flow rate to 50ml / min, and the purge time to 30min. The analysis conditions of the GC-MS are set in accordance with HJ / T 400-2007 "Sampling and Determination Methods for Volatile Organic Compounds and Aldehydes and Ketones in Vehicles".

[0029] 3. Confirm that the GCMS analysis results are shown in the table below

[0030]

[0031] 4. Determine the response coefficient of the compound by the method of ZL2020 10509820.9
