PSP106型色谱仪
PSP106型色谱仪符合GB/T13610-2003《天然气的组成分析气相色谱法》广泛应用于燃气具生产企业、燃气计量检测部门、科研、环保和配气等行业。
天然气是由多种组分构成的混合物。天然气的组成是指天然气中所含的组分及其在可检测范围内的相应含量。在检测时通常所指的组成是指天然气中甲烷、乙烷等烃类组分和N2、CO2等常见的非烃组分的含量。尽管天然气还含有如硫化物、水等杂质，但如果不特别说明，在组成分析时并不检测这些组分。在商品天然气的组分分析中，由于组分相对稳定，只要求对Cl至C6的烃类组分进行简单分析(也称常规分析)。
目前，我国针对天然气组分分析的气相色谱法，制定的标准《GB/T13610一2003天然气的组成分析一气相色谱法》采用外标法，检测器使用热导检测器(TCD)。我们需要通过气相色谱仪分析天然气的组分，并根据组分来计算其密度，压缩因子，发热量等。
PSP106型色谱仪是我公司紧跟科技发展进程，按照国家标准研制的实现全自动化的一体式分析仪器，将发生器、分析仪、电脑、色谱工作站合为一体，通过一次进样可以完成气体中含量的精确分析。仪器内置八核处理器平板电脑，直接在仪器屏幕上显示分析结果，方便，快捷。
特点：
电子线路集成度高，可靠性好，操作简单，保证仪器质量稳定、可靠，既保证了工作效率又节约维修费用，自动记忆运行参数，开机不需重设。
仪器采用氢气发生器、分析仪、工作站、电脑一体式设计，只需一台仪器就可完成整个分析，检测过程更简单化。
气路系统采用高精度阀结构，使得仪器气体速的稳定性大大提高，从而获得良好重现性的分析结果。
检测完毕仪器屏幕直接出谱图结果。

PSP106 chromatograph
PSP106 chromatograph conforms to GB / T13610-2003 "Composition Analysis of Natural Gas by Gas Chromatography" and is widely used in gas appliance manufacturers, gas measurement and testing departments, scientific research, environmental protection and gas distribution industries.
Natural gas is a mixture of many components. The composition of natural gas refers to the components contained in natural gas and their corresponding contents within a detectable range. The composition usually referred to when testing refers to the content of hydrocarbon components such as methane, ethane, and common non-hydrocarbon components such as N2 and CO2 in natural gas. Although natural gas also contains impurities such as sulfides and water, these components are not tested during composition analysis unless otherwise specified. In the composition analysis of commercial natural gas, because the composition is relatively stable, only simple analysis (also called conventional analysis) of the hydrocarbon components of Cl to C6 is required.
At present, Chinas gas chromatography method for the analysis of natural gas components, the national recommended standard "GB / T13610-2003 Natural gas composition analysis-gas chromatography" adopts the external standard method, and the detector uses a thermal conductivity detector (TCD). We need to analyze the composition of natural gas by gas chromatograph, and calculate its density, compression factor, heat generation, etc. based on the composition.
PSP106 chromatograph is our companys latest development in accordance with national standards to achieve a fully automated integrated analysis instrument that closely follows the development of science and technology. It combines generators, analyzers, computers, and chromatographic workstations. Gas can be completed in one injection. Accurate analysis of medium content. The instrument has a built-in eight-core processor tablet computer, which displays the analysis results directly on the instrument screen, which is convenient and fast.
Features:
The electronic circuit has a high degree of integration, good reliability, and simple operation, which guarantees the stable and reliable quality of the instrument, which not only guarantees work efficiency and saves maintenance costs, it automatically remembers operating parameters and does not need to be reset when it is turned on.
The instrument adopts an integrated design of hydrogen generator, analyzer, workstation, and computer. Only one instrument can complete the entire analysis, and the detection process is simpler.
The gas system uses a high-precision valve structure, which greatly improves the stability of the gas velocity of the instrument, thereby obtaining a good reproducible analysis result.
After the test, the instrument screen directly displays the spectrum results.
It can analyze the content of nitrogen, carbon dioxide, methane, ethane, propane, isobutane, n-butane, isopentane, n-pentane and other components in natural gas. The calorific value, natural white number, density, etc. of natural gas can also be accurately calculated by the content of each component.
