1. Test principle

1. Testing principle of volatile organic components

VOC test chamber for car interior parts by bag method After placing the test material in a sealed nitrogen and heating it at a specified temperature for 2 hours, a certain volume of air sample was collected using a TENAX tube, and the volatile organic components in the sample were trapped in the sampling tube. The sampling tube is purged with dry inert gas and then enters the capillary gas chromatography-mass spectrometer through secondary desorption, so as to perform qualitative and quantitative analysis of volatile organic components.

2.VOC test chamber for car interior parts by bag method Testing principle of aldehydes and ketones

Place the test material in a sealed nitrogen and heat it at a specified temperature for 2 hours, and then use a DNPH tube to collect a certain volume of air sample. The aldehyde and ketone components in the sample are trapped in the sampling tube. Elute with 60% acetonitrile/40% aqueous solution, and use high performance liquid chromatography to perform qualitative and quantitative analysis of aldehydes and ketones.
