GDX-104色谱填料主要应用

GDX-104由于其非极性、热稳定性好（*高使用温度可达270℃）、耐腐蚀以及较大的比表面积（约590m²/g）等特点，在许多分析场景中都是理想选择：

环境监测 - 非甲烷总烃（NMHC）分析：这是GDX-104非常经典和重要的应用。非甲烷总烃通常指除甲烷以外的所有可挥发的碳氢化合物（主要是C2~C8）1。它们对人体健康和环境（如形成光化学烟雾）有潜在危害。GDX-104填充柱可用于测定环境空气以及废气中的非甲烷总烃浓度。此应用常配合氢火焰离子化检测器（FID），通过特定分析方法（如利用六通阀定量环进样）能较好地分离甲烷和总烃，从而准确计算非甲烷总烃含量。

能源化工气体分析：GDX-104适用于多种工业气体的成分分析。

可用于分析半水煤气中的二氧化碳和甲烷。用于焦炉煤气中二氧化碳、乙烯、乙烷、乙炔、丙烯、丙烷等组分的分析。应用于天然气、液化石油气以及炼厂气等能源气体的分析。

化学品与溶剂分析：GDX-104也能用于一些特定液体化学品或溶剂中组分或杂质的测定。

醇类和水分的分析：例如，采用热导池检测器（TCD）时，GDX-104可在不用固定液的情况下同时测定乙醇、甲醇及水的含量。其他有机物：资料提及GDX-104还可用于分析酸、醛、醇、酯等化合物，以及二甲醚、甲缩醛、粗苯等。

其他特殊应用：

微量水分的分析：例如，可用于丁二烯及异丁烯中微量水的分析。特定行业应用：资料显示GDX-104还可用于变压器油溶解气分析、环氧乙烷残留检测、植物油中6号溶剂残留分析等。

Main applications of GDX-104 chromatographic packing
GDX-104 is an ideal choice in many analytical scenarios due to its non-polar nature, good thermal stability (up to 270 ℃), corrosion resistance, and large specific surface area (approximately 590m ²/g)
Environmental Monitoring - Non Methane Total Hydrocarbons (NMHC) Analysis: This is a very classic and important application of GDX-104. Non methane total hydrocarbons usually refer to all volatile hydrocarbons (mainly C2~C8) except methane. They have potential hazards to human health and the environment, such as the formation of photochemical smog. GDX-104 packed column can be used to determine the concentration of non methane total hydrocarbons in ambient air and exhaust gas. This application is often used in conjunction with a hydrogen flame ionization detector (FID), which can effectively separate methane and total hydrocarbons through specific analysis methods (such as using a six way valve quantitative ring injection), thereby accurately calculating the non methane total hydrocarbon content.
Energy and chemical gas analysis: GDX-104 is suitable for component analysis of various industrial gases.
Can be used to analyze carbon dioxide and methane in semi water gas. Used for the analysis of carbon dioxide, ethylene, ethane, acetylene, propylene, propane and other components in coke oven gas. Applied to the analysis of energy gases such as natural gas, liquefied petroleum gas, and refinery gas.
Chemical and solvent analysis: GDX-104 can also be used for the determination of components or impurities in certain liquid chemicals or solvents.
Analysis of alcohols and water: For example, when using a thermal conductivity cell detector (TCD), GDX-104 can simultaneously determine the content of ethanol, methanol, and water without the need for a fixed liquid. Other organic compounds: Data mentions that GDX-104 can also be used to analyze compounds such as acids, aldehydes, alcohols, esters, as well as dimethyl ether, formaldehyde, crude benzene, etc.
Other special applications:
Analysis of trace water: For example, it can be used for the analysis of trace water in butadiene and isobutene. Specific industry applications: Data shows that GDX-104 can also be used for analysis of dissolved gases in transformer oil, detection of residual epoxyethane in medical devices, and analysis of residual solvent No. 6 in vegetable oil.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. is responsible for the development and production of GDX-104 packed chromatography column application Shimadzu GC2010. GDX-104 chromatographic packing plays an important role in gas analysis and non methane total hydrocarbon determination due to its stability, hydrophobicity, and wide applicability. Of course, the specific analysis conditions (such as column temperature, carrier gas flow rate, etc.) need to be optimized based on your actual sample type, analysis objectives, and the gas chromatograph used.
