GDX-502的基本特性
化学性质：
由苯乙烯-二乙烯苯共聚物制成，表面为惰性，对极性物质吸附性较弱。
适用于分析水、醇、醛、酸等极性化合物，且峰形对称，拖尾小。
物理性质：
多孔结构，比表面积较大，适合分离小分子气体和挥发性有机物。
*高使用温度约为250℃，可应用于高温分析。
优点：
对水分吸附性低，适合含水样品的直接进样。
耐酸碱腐蚀，可分析腐蚀性气体（如HCl、NH₃等）。

Basic characteristics of GDX-502
Chemical properties:
Made from styrene divinylbenzene copolymer, the surface is inert and has weak adsorption for polar substances.
Suitable for analyzing polar compounds such as water, alcohols, aldehydes, acids, etc., with symmetrical peak shapes and small tails.
physical property:
Porous structure with a large specific surface area, suitable for separating small molecule gases and volatile organic compounds.
The maximum operating temperature is about 250 ℃, which can be used for high-temperature analysis.
Advantages:
Low water adsorption capacity, suitable for direct injection of water containing samples.
Acid and alkali corrosion resistance, capable of analyzing corrosive gases such as HCl, NH3, etc.
