PSP106型色譜儀
PSP106型色譜儀符合GB/T13610-2003《天然氣的組成分析氣相色譜法》廣泛應(yīng)用于燃?xì)饩呱a(chǎn)企業(yè)、燃?xì)庥嬃繖z測部門、科研、環(huán)保和配氣等行業(yè)。
天然氣是由多種組分構(gòu)成的混合物。天然氣的組成是指天然氣中所含的組分及其在可檢測范圍內(nèi)的相應(yīng)含量。在檢測時通常所指的組成是指天然氣中甲烷、乙烷等烴類組分和N2、CO2等常見的非烴組分的含量。盡管天然氣還含有如硫化物、水等雜質(zhì)，但如果不特別說明，在組成分析時并不檢測這些組分。在商品天然氣的組分分析中，由于組分相對穩(wěn)定，只要求對Cl至C6的烴類組分進(jìn)行簡單分析(也稱常規(guī)分析)。
目前，我國針對天然氣組分分析的氣相色譜法，制定的標(biāo)準(zhǔn)《GB/T13610一2003天然氣的組成分析一氣相色譜法》采用外標(biāo)法，檢測器使用熱導(dǎo)檢測器(TCD)。我們需要通過氣相色譜儀分析天然氣的組分，并根據(jù)組分來計算其密度，壓縮因子，發(fā)熱量等。
PSP106型色譜儀是我公司緊跟科技發(fā)展進(jìn)程，按照國家標(biāo)準(zhǔn)研制的實現(xiàn)全自動化的一體式分析儀器，將發(fā)生器、分析儀、電腦、色譜工作站合為一體，通過一次進(jìn)樣可以完成氣體中含量的精確分析。儀器內(nèi)置八核處理器平板電腦，直接在儀器屏幕上顯示分析結(jié)果，方便，快捷。
特點：
電子線路集成度高，可靠性好，操作簡單，保證儀器質(zhì)量穩(wěn)定、可靠，既保證了工作效率又節(jié)約維修費(fèi)用，自動記憶運(yùn)行參數(shù)，開機(jī)不需重設(shè)。
儀器采用氫氣發(fā)生器、分析儀、工作站、電腦一體式設(shè)計，只需一臺儀器就可完成整個分析，檢測過程更簡單化。
氣路系統(tǒng)采用高精度閥結(jié)構(gòu)，使得儀器氣體速的穩(wěn)定性大大提高，從而獲得良好重現(xiàn)性的分析結(jié)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.
