1、General purpose columns with high temperature,ultra-low bleed phases,ideal for semivolatiles,pestidides,PCB comgeners or（e.g.）Aroclor mixes,other environmental applications.

2、Stable to 360度.

3、Equivalent to USP G27,G36 phases.

XTI-5 columns have the lowest bleed and highest maximum operating temperature of any 5% diphenyl/95% dimethyl polysiloxane capillary column.They exhibit excellent inertness for all reactive compounds in environmental applications,and the efficiency needed to resolve closely eluting isomers.Every XTI-5 column is evaluated with a test mix composed of many of the most adsorptive environmental target compounds,and is tested to ensure low bleed at maximum operating temperature.

該柱可用于半揮發(fā)農(nóng)藥、多氯苯類、環(huán)境樣品及提煉油品等方面的分析。
該柱同樣是交聯(lián)鍵合相，所以也可用溶劑淋洗。
