由於離子液體應用於氣相層析靜相材料的研究愈加蓬勃，但目前亦顯見其更突破高溫耐溫性之研究瓶頸，而管柱的耐高溫程度會影響至其管柱的溫度分離範圍及分離樣品的多寡。
而在石油內含有許多化合物，具有高熔點、高沸點的特性，如瀝青、多環芳香烴等以往並不受到重視，而今亦逐漸發展出新式用途，如瀝青還可以繼續加工，得到瀝青纖維，再經碳化製成碳纖維，是優質碳纖維複合材料的重要增強體。還有如環境中多環性芳香化合物常在空氣中的懸浮微粒上發現，其中已有許多的多環芳香烴為人熟知的致癌物，對於人體健康有極大傷害。
為了前述的發展應用，亦為了搭配氣相層析的方便、簡易操作性。如同前面離子液體之介紹，咪唑陽離子型之離子液體有著優秀的耐熱性，故此便以咪唑陽離子為主體，加入不同之交聯劑，從中研究及改善更優越之耐高溫管柱。
起始物之長鏈型咪唑類聚離子液體主體為P[C6imi+] [NTf2-]，末端基為乙烯基。聚合劑則為乙烯苯及短鏈型咪唑類離子液體兩種，改變不同合成比例和動態塗附之濃度，檢視個別耐溫性質及分離效率。
以短鏈型咪唑類聚離子液體作為聚合劑成果最佳，使之分離塑化劑混合標準品、多環芳香烴混合標準品、直鏈烷類混合標準品及煤焦油真實樣品，檢驗管柱之分離效率、靜相性質探討，最終與市售管柱之分析圖譜作比較，更進一步分析推論本實驗成果鑑定。

With the diverse development of ionic liquid used for stationary phase in gas chromatography (GC), it breaks the choke point of heat-resistance of stationary phase. The applicability of sample and the peak capacity could be decided by the heat-resistance of the GC column.
Many compounds in crude oil have high melting point and boiling point. In the past, the coal tar and polycyclic aromatic hydrocarbons (PAHs) had not been being paid attention. But now we have found their new applications of commercial use. For example, the asphalt can be refined into the strengthening agents to manufacture the high-quality composite materials of carbon fibers. The environmental PAHs are found in the suspended particles in the air, some of them are defined as carcinogens. They are seriously harmful to human health.
In this study, the convenience and simple operability of GC system and ionic liquids of imidazolium group with high heat-resistance were combined. The GC stationary phases were prepared from imidazolium compounds by adding different cross-linking agents.
The initial agent is a long chain poly[C6imidazolium+][NTf2-] with vinyl group on the end terminal. The cross-linking agents are vinyl benzene and short chain poly[C6imidazolium+][NTf2-]. It was found that heat-resistance of GC stationary phase and peak resolution in chromatogram which are related to the amount of cross-linking agent added in re-polymerization synthesis and the concentration of the dynamical coating solution.
Finally, the prepared GC columns were tested to analyze the phthalate esters mix standard, PAHs mix standard, n-hydrocarbon mix standard, and real sample of coal tar. Compare with the commercial GC capillary column, the properties such as stability at high temperature and peak resolution in chromatogram of the GC capillary columns were discussed in this research. The applicability of the prepared GC columns were confirmed by the testing results.
