Introduction : We know that the gas chromatograph in the daily analysis, up to 10% the size of the error from the operation of the instrument, and to 90% from sample handling is good or bad, to the advantages and disadvantages of different sample processing techniques and methods and there is a big different, where the use of a headspace (vapor extraction) gas chromatography analysis, can achieve almost any volatile compounds in the sample accurate, simple, quick analysis. Because headspace extremely easy realization of liquid and solid samples without solvent extraction, it can be said as fundamentally eliminated: adsorption solution echoed Sample solvent extraction processing methods, possible errors and problems. Features: 1, accurate, simple, fast, easy, automatic and environmental protection; 2, high-sensitivity analysis of volatile components in the sample; 3, Due to the high boiling components are not imported GC, can shorten the analysis time and doubling improve work efficiency; 4, Due to the high boiling components are not imported GC, to avoid contamination of high boiling components analysis system, thus reducing some of the key components of the instrument routine maintenance work, and may be extended up (eg: injector, column, detector, etc.) lifetime; Technical parameters: Temperature control accuracy: ± 0.5 ℃; Temperature control gradient: ± 0.5 ℃; Vial Size: Standard 20 mL (10 mL 50 mL and other specifications can be customized); Repeatability: RSD <3% (and GC performance-related); Quantitative tube specifications: Standard 1mL (with 0.5mL 3mL); injection pressure range: 0 MPa ~ 0.4 MPa (continuously adjustable); effective size: 200 mm × 360 mm × 420 mm; weight: about 12 kg.
