We have also established an accute and effective calibrating system-gas chromatography and solid phase micro extraction (SPME).
并且还建立了一套准确而有效的气相色谱和固相微萃取定标系统。

RESULTS: The micro character and thin layer chromatography was clear with no disturbance of negative sample.
结果：显微鉴别特征明显、薄层色普清晰，空白样品无干扰；

The deactivation kinetics for the vapor-phase disproportionation of toluene over mordenite catalyst has been studied by using a combined unit of micro-reactor under pressure and gas chromatography.
