Porapak Q 是 经典的多孔聚合物 GC 填料，在 气体、轻烃、水溶性 VOCs 分离 中仍有广泛应用，尤其适合 含水样品 和 极性-非极性混合体系。
极性分类：非极性至弱极性填料，与 苯乙烯-二乙烯基苯树脂（类似 Amberlite XAD 系列） 结构相似。
温度范围：通常 -50°C 至 250°C（长期使用建议 ≤200°C），高温下可能发生降解。
分离机理：基于 吸附-分配复合机理，孔径分布均匀，适合分离分子量 < 300 Da 的化合物。
水峰行为：对水峰拖尾抑制较好，但含水量过高时仍需谨慎。

Porapak Q is a classic porous polymer GC filler that still has wide applications in the separation of gases, light hydrocarbons, and water-soluble VOCs, especially suitable for aqueous samples and polar non-polar mixed systems.
Polarity classification: non-polar to weakly polar fillers, structurally similar to styrene divinylbenzene resin (similar to Amberlite XAD series).
Temperature range: typically -50 ° C to 250 ° C (long-term use recommended ≤ 200 ° C), degradation may occur at high temperatures.
Separation mechanism: Based on the adsorption distribution composite mechanism, the pore size distribution is uniform, suitable for separating compounds with molecular weight<300 Da.
Water peak behavior: Good suppression of water peak tailing, but caution is still needed when the water content is too high.
