Determination of n-butanol in workplace air by capillary gas chromatography
N-butanol has stimulating and anesthetic effects. The main symptoms are irritation of the eyes, nose, and throat, formation of semi transparent vacuoles in the superficial cornea, headache, dizziness, and drowsiness, and contact dermatitis may occur in the hands. Therefore, it is necessary to carry out the detection of n-butanol in the air of the workplace. This article refers to the current national standard method GBZ/T 160.48-2007 "Determination of Alcoholic Compounds in Workplace Air Toxic Substances" and related specifications, using HP-INNOVAX capillary chromatography column, solvent desorption gas phase chromatography
The spectral method was studied for the determination of n-butanol in the air. The method has good repeatability and the detection sensitivity can meet the requirements. At the same time, the detection limit, precision, and desorption efficiency of the method were tested
key word:Gas chromatography, chromatography; Direct injection gas chromatography technology; Capillary gas chromatography; Workplace air quality; n-butanol

3、 Spectrum of n-butanol in the air:
GC-2010 gas chromatograph is a separation and analysis tool for multi-component mixtures. It uses gas as the mobile phase and employs column chromatography technology with flushing method. When the automatic sample preparation and injection device pushes multiple components of analytical substances into the chromatographic column, due to the different distribution coefficients between the gas phase and the fixed liquid liquid phase of each component in the chromatographic column, the operating speed of each component in the chromatographic column is also different. After a certain column length, the components leave the chromatographic column in sequence and enter the detector. After detection, they are converted into electrical signals and sent to the data processing workstation, thus completing the fully automatic qualitative and quantitative analysis of the tested substance. Its automatic sample preparation and injection function eliminates the inevitable operational errors of manual injection, and can be widely applied to the detection of various materials, gases, odors, residues, cigarette packs and other related indicators with ultra-high accuracy; It is the * choice for gas chromatography analysis and control in testing institutions, research institutes, packaging enterprises, food and drug industries, etc.
