1，*符合ASTM測試方法D-2887的性能要求；

2，采用交聯(lián)技術(shù)（Crossbond)保證壽命長，老化時間短，允許溶劑漂洗

3，MXT-2887柱使用了Sicosteel處理的不銹鋼柱管，防止了在高溫斷、脆易裂的缺點；

4，本色譜柱與DB-2887，Petrocol^TM2887,以及Petrocol^TMEX2887柱相似；

A,Application-specific columns for simulated distilation.

B,Rtx-2887 stable to 360^oC,MXT-2887 stable to 400^oC.

Rtx-2887 and MXT-2887 columns^,stationary phase,column dimensions,and film thickness have been optimized to exceed the resolution and skewing factor requirements currently specified in ASTM method D-2887.Each column is individually tested to guarantee astable baseline with low bleed and reproducible retention times.The Crossbond methyl silicone stationary phase has increased stability compared to packed columns,ensuring stable baselines and shorter conditioning times.The most durable high temperature GC columns available are Restek^,s MXT columns,manufactured from silcosteel-treated stainless steel tubing.
