Car air quality inspection
To evaluate the in-car air benzene, toluene, xylene, ethylbenzene, styrene and the concentration of formaldehyde, acetaldehyde, acrolein, etc, the vehicle VOC testing the car in place standard environment, according to the standard requirement to execute (ready to stage a seal stage sampling stage) program, the sampling stage, TENAX tube gathering benzene series plant-based material, TD - GCMS analysis;Aldehydes and ketones were collected from DNPH tubes and analyzed by HPLC.
Testing standard
HJ/T 400-2007 Determination of Volatile Organic Compounds and Carbonyl Compounds in Cabin of Vehiclse
GB/T 27630-2011 Guideline for air quality assessment of passenger car
Odor
Odor test is based on people's sense of smell and comfort. It can evaluate all the odors emitted by automobile interior decoration subjectively and directly reflect the advantages and disadvantages of automobile interior decoration.
Formaldehyde (aldosterone) test
The test of formaldehyde (aldehydes) simulates the volatilization of automobile interior decoration and materials under sunlight, and examines the advantages and disadvantages of automobile interior decoration by monitoring the volatilization gas.
Fogging test
Fogging test is to simulate the condensation phenomenon of volatile gases on the Windows or windshields of automobile interior decorations and materials under the sunlight by means of atomization tester.Through different ways to monitor the fog value of glass, examine the pros and cons of automotive interior trim
VOC of Sampling (Sampling bag test)
The auto interior parts were sealed in Tedlar sampling bag, filled with nitrogen of a fixed volume, heated at a specified temperature for a period of time, and then the benzene series materials were collected by TENAX tube and analyzed by the thermal desaturation temperature-coupled system (TD-GC/MS).Flavonoid was collected by DNPH tube and analyzed by liquid chromatography (LC DAD).
VOC of Material
Material VOC analysis is a temperature-related system that takes trace of automotive interior materials and places them in a clean empty glass tube.Qualitative and quantitative analysis of volatile components by GC/MS.

TVOC
TVOC are organic compounds whose boiling point is 50 ~260℃ under normal pressure. The total carbon test analyzes the total amount of VOCs by gas chromatography nonpolar column, and evaluates the quality of components and materials that influence the air quality in the vehicle.
