煉油廠和其他氣體中輕質烴的測定，通常通過填充柱和機械旋轉閥進行。例如，ASTM方法D-2597采用了這一辦法。氣體取樣閥將少量計量後的樣品氣體，送入非極性填充柱。C1到C5碳氫化合物可從該色譜柱中洗脫，並進入第二個帶有極性固定相的填充色譜柱。在這一點上，旋轉閥被啟動，以使載氣反向流過預柱，並將該柱中的任何殘餘樣品反衝至檢測器，以測定樣品中的總C6+含量。同時，C1至C5含量的色譜在第二個柱上進行分離、鑒定和定量。整個分析過程大約需要20分鍾，由於色譜柱的正常變化，如何獲得可接受的色譜分離通常是一個挑戰。

量的反應雜質也能夠引起藥物明顯的穩定性問題，因為就重量和摩爾質量而言，輔料遠超過API。痕量的反應產物也很容易超過多數藥品關於降解產物低於0.2%的限量要求。輔料中的甲醛能夠與藥品降解產物中的初級和/或二級胺基團形成聚合物。也有報道指出，甲醛能夠導致膠囊凝膠鍵合，從而引起藥物體外分解的不利效果。由於醛類物質極高的活性，在藥物的配方設計過程中，及時評估輔料中醛類物質的存在，對避免後續藥物研發過程發生無法預料的穩定性問題至關重要。
