涂壁开板玻璃毛细管柱可用于二萜树脂酸甲酯混合物的定性气液色谱分析。本文给出了77种化合物在六种固定相（Silar 10 C、BDS、SP-2330、SP-1000、SE-54和SE-30）上的溶液特性。对于大多数应用，两个固定相，一个极性和另一个非极性，将足够。当典型尺寸的样品通过自动进样器进样到入口分流器中时，定量数据的重现性被发现是不可接受的。然而，通过将大量样品（每种组分超过20 ng）注入色谱柱，可以获得可靠的定量数据。
Wall-coated open-tabular glass capillary columns are useful for the qualitative gas—liquid chromatographic analysis of diterpene resin acid methyl ester mixtures. The solution characteristics of 77 compounds on six liquid stationary phases (Silar 10C, BDS, SP-2330, SP-1000, SE-54 and SE-30) are given. For most applications, two stationary phases, one polar and the other non-polasr, will suffice. The reproductibility of quantitative data was found to be unacceptable when typical size samples were injected into an inlet splitter by an automatic injector. However, by injecting large samples (over 20 ng per component on to the column) reliable quantitative data are obtainable.
