State reaches HPLC liquid chromatograph used to identify substances analysis determined its preparations containing various drugs determination, especially the separation of biological samples, medicine and other ingredients to fly complex system analysis, quantitative and qualitative. High performance liquid chromatograph system consists reservoir, pump, injector, column, detector, recorder, etc. several parts. reservoir of mobile phase is high-pressure pump into the system, the sample solution by injection When the mobile phase is entered, the mobile phase is loaded the column (stationary phase), the sample solution is due to the components of the two phases have different distribution coefficients, the relative motion of two phases, through the repeated adsorption - desorption allocation process, the components generating a large difference in the movement speed, it is separated into the individual components in order from the column effluent, through the detector, the concentration of the sample is converted into an electrical signal transmitted to the recorder, the data in order to print out the map in the form of high performance liquid chromatography requires only a sample solution can be made, without limitation volatile sample, mobile phase wide range of choice, many types of stationary phase, and thus can be separated thermally unstable and non-volatile nature, away from the non-dissociated and substances of various molecular weight range of solution. cooperates with the sample pretreatment, HPLC achieved high resolution and high sensitivity, the separation and simultaneous determination of a substance very similar in nature as possible , can be separated from the body of the complex phase of trace elements. With the development of the stationary phase, there may be sufficient to maintain biochemical substances under the conditions of the activity to complete its separation. HPLC biochemical analysis to solve problems become the most promising approach. Because of HPLC with a high resolution rate, high sensitivity, high speed, the column can be repeatedly used, the outflow component is easy to collect, etc., which are widely applied to biochemistry, food analysis, study various fields of medicine, environmental analysis, inorganic analysis. HPLC instrument associated with the structure of the instrument with an important direction of development. chromatograph for analysis of chromatographic separation apparatus including injection systems, detection systems, recording and data processing systems, temperature control systems, and mobile phase control systems. Modern chromatograph with the stability, sensitivity, versatility and high degree of automation. There are high-performance liquid chromatography, chromatography workstation, solid phase extraction device, nitrogen blowing instrument, a differential detector, evaporative light scattering detector, automatic feed sampler, gas chromatography, nitrogen blowing instrument, thermal analysis instrument, headspace, air compressors, hydrogen generators, nitrogen generators, three gas one machine, the hydrogen flame detector, NPD, FPD detector, electron capture detector, thermal conductivity detector, gas chromatography purification, etc. These products are widely used in the chemical analysis of the content of the polymer material in some countries up to chromatography Mall Address: Zhengzhou Zhongyuan District TONGBAI Road 98 A District Dili Dili Lake Garden Lake Palace Room 811, Building 3103 GUODA chromatography Mall Tel: 0371-68850806 / 68850808 GUODA chromatography Mall Fax: 0371-68811223 / 68811229 GUODA chromatography Mall mail: 2350470569@qq.com country up chromatographic Mall Online Service QQ: 2350470569 GUODA chromatography mall free phone 400-1158-566 GUODA instrument Mall www.gd226.cn GUODA chromatography consumables Mall www.guodasepu.com
