浩瀚GDX-105气相色谱柱应用在安捷伦7890B上6m*3mm

GDX-105化学组成与结构
由二乙烯苯与乙基乙烯苯（或苯乙烯）共聚而成的高分子多孔微球，呈透明状，属非极性固定相。
孔径小、表孔密集，比表面积达610 m²/g，堆密度0.44 g/mL178。
理化学性能
耐温性：*高使用温度270℃，热稳定性良好。
抗性：耐腐蚀、耐辐射，机械强度高。
局限：表面存在活性吸附中心，分析极性物质时可能引起色谱峰拖尾或不可逆吸附（如萜烯、含氮杂环化物等），需钝化处理

主要适用于气体和微量水分析，具体场景包括：
工业气体分析
半水煤气中的CO₂、甲烷；丁二烯、异丁烯中的微量水28。
烟道气中CO₂分离（常与分子筛柱联用，如5Å分子筛分离O₂/N₂/CO）。
污染物检测
固定污染源废气中氯乙烯：1.2m×3mm不锈钢柱，检出限0.15 mg/m³，相对标准偏差1.9%–5.8%。
液化石油气中非法添加的二甲醚及甲醇：3m×3mm柱，载气流量30 mL/min（H₂或He），热导检测器，归一化法定量。

Chemical Composition and Structure of GDX-105
Polymer porous microspheres formed by copolymerization of divinylbenzene and ethylethylethylbenzene (or styrene), which are transparent and belong to non-polar stationary phases.
Small pore size and dense surface pores, with a specific surface area of 610 m ²/g and a bulk density of 0.44 g/mL178.
Physical and chemical properties
Temperature resistance: The maximum operating temperature is 270 ℃, and the thermal stability is good.
Resistance: Corrosion resistance, radiation resistance, high mechanical strength.
Limitations: There are active adsorption centers on the surface, which may cause chromatographic peak tailing or irreversible adsorption when analyzing polar substances (such as terpenes, nitrogen-containing heterocyclic compounds, etc.), requiring passivation treatment
Mainly suitable for gas and trace water analysis, specific scenarios include:
Industrial gas analysis
CO ₂ and methane in semi water gas; Trace water in butadiene and isobutene 28.
CO ₂ separation in flue gas (often used in conjunction with molecular sieve columns, such as separating O ₂/N ₂/CO with 5 Å molecular sieves).
Pollutant detection
Chloroethylene in fixed pollution source exhaust gas: 1.2m × 3mm stainless steel column, detection limit 0.15 mg/m ³, relative standard deviation 1.9% -5.8%.
Illegal addition of dimethyl ether and methanol in liquefied petroleum gas: 3m × 3mm column, carrier gas flow rate of 30 mL/min (H ₂ or He), thermal conductivity detector, normalization method for quantification.
Name: Gas filled Column
Specification and model: 6m * 3mm, GDX-105
Maximum operating temperature: 270 ° C
Application: Determination of trace moisture in chemical products, analysis of fusel oil, gas, and vinyl chloride
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed and produced the "GDX-105 Filled Chromatography Column Application Shimadzu GC2010": GDX-105, with its high specific surface area and non-polar microporous structure, has become an ideal choice for the analysis of trace water, permanent gases, and small molecule volatile organic compounds, especially in environmental monitoring (vinyl chloride), energy quality inspection (dimethyl ether), and industrial process gas control. Strictly follow the aging and deoxygenation process during use to ensure column efficiency and reproducibility of analysis.
