Using the topological indexes , the separation factors of fullerenes in bonded phases are predicated 運用拓撲指數(shù),預測了鍵合相中富烯勒的分離因子。
The separation of fullerenes using hplc is studied from the perspective of the molecular structure of the bonded phase in the chromatographic column 從色譜柱中鍵合相分子結構的角度,研究了富勒烯hplc分離。
Porous silica , especially silica bonded phases ( sbp ) of hplc , was also introduced to spme as fiber coating , which had higher extraction capacity , shorter analysis time and higher sensitivity . in this paper , we introduced novel mesoporous material c16 - mcm - 41 to prepare spme fibers 本文首次將c _ ( 16 ) - mcm - 41介孔材料用作spme纖維涂層,制成萃取頭,并以此萃取測定了環(huán)境樣品中的多環(huán)芳烴。
Nonpolar filler are used in reversed phase chromatographic system , of which , octadecylsilane chemically bonded silica is most commonly used , sometimes , octyl chemically bonded silica and other types of chemically bonded silica ( such as cyano chemically bonded phase and amino chemically bonded phase , etc ) are also used as well 反相色譜系統(tǒng)使用非極性填充劑,以十八烷基硅烷鍵合硅膠最為常用,辛基硅烷鍵合硅膠和其他類型的硅烷鍵合硅膠(如氰基硅烷鍵合相和氨基硅烷鍵合相等)也有使用。
