Guoda Instrument Co., Ltd. is a high-tech enterprise specializing in R&D, production, sales and service of chromatography products and laboratory equipment. Sales and customer service outlets throughout the country have developed into an integrated supplier of instrumentation and chromatography consumables with a certain influence and scale in the domestic analysis industry.
The headspace sampling method is a convenient and efficient sample preparation method in separation. The principle is to put the sample to be tested into a closed container, and the volatile components are volatilized from the sample matrix by heating and heating, in the gas-liquid (or gas-solid) equilibrium is achieved in both phases, and the top gas is directly extracted for chromatographic analysis to examine the composition and content of volatile components in the sample. The use of headspace sampling technology eliminates the tedious and tedious sample preparation process, avoids interference from organic solvents and reduces contamination of the column and inlet. Because of the intelligence and convenience of the headspace injection method, the application is very extensive. The national standard and the 2015 edition of the Chinese Pharmacopoeia mostly use the headspace injection method for the detection of the hair component (residual solvent). Guoda Instruments hereby launches a new generation of GD series intelligent headspace sampler with unique technical features and independent intellectual property rights.
GD series intelligent headspace sampler adopts graphically designed touch color screen control interface, Chinese/English display and input, one-button operation, can be combined with any brand of GC or GC/MC, gas path and segmentation Automatic leak detection and fault alarm, diagnostic log, can store 10 user-defined analysis methods, multiple headspace (MHE) extraction mode, time setting sampling and volume setting sampling technology compatible, making the operation of the instrument more flexible and convenient , 12 constant temperature sample stations, sample heating furnace temperature and control range: room temperature ~ 400 ° C, the whole machine's transmission tube is passivated and polished, sample transfer tube temperature and control range: room temperature ~ 220 ° C, more clear modular The structure minimizes residual and dead volume. The highly efficient six-way valve assembly optimizes sample sampling and injection. The volume of the loop: for example, 0.5ml, 1ml, 3ml, 5ml, can also be customized according to customer requirements, six-way valve Injection system temperature and control range: room temperature ~ 260 °C.
Advanced full-flow automatic purging function, with communication interface for synchronously starting chromatographic data processing workstation, temperature increment control ±1 °C, temperature control accuracy: ±0.1 °C. The new high-tech intelligent control system ensures accurate and perfect reproducibility of sample test results! Let people make the error and process error all "0", track technical services, enjoy one-on-one technical guidance service, let all users buy the peace of mind, with peace of mind!
