Abstract

The invention discloses a separation method and a determination method for volatile acrolein and acetone in automobile interior trim parts, wherein the separation method comprises the following steps:a mixed aldehyde ketone-DNPH standard solution with a concentration of 1mg / L was allocated and injected into the chromatographic column of the liquid chromatograph; according to the peak time and thepeak shape of the chromatogram waveform diagram and the separation effect of the acrolein and acetone, and a target flow rate is selected under the same sample inlet volume, the detector wavelength,the column temperature and the mobile phase ratio; a target column temperature is selected under the same sample inlet volume, the detector wavelength, flow velocity and the flow matching ratio; a target flow phase ratio is selected under the same sample inlet volume, detector wavelength, the flow rate and the column temperature condition; the acrolein and the acetone are separated according to the target flow rate, the target column temperature and the target flow phase ratio. By means of the invention, the separation effect of acetone and acrolein by liquid chromatography is tested, and theoptimal separation detection conditions are determined according to factors such as peak time, peak shape and separation degree of substances under different conditions.

Description

technical field [0001] The invention relates to the field of auto inspection, in particular to a method for separating and measuring acrolein and acetone, which are volatiles in automotive interior parts. Background technique [0002] In recent years, with the rapid development of the domestic automobile industry and the automobile industry, more and more materials are used in the interior parts of automobiles, and the air quality in the car has gradually attracted people's attention. In-vehicle air pollution sources mainly include automotive interior materials, such as artificial leather, textiles, plastics and a series of pollution sources. Formaldehyde, acetaldehyde, acrolein, and other volatile organic compounds (VOC) released by these pollution sources, as well as amines and nicotine produced by the operation of automobile air conditioners. Among them, the volatile organic compounds (VOC) in the car interior are the main cause of affecting the quality of the air in the...
