Dionex  BorateTrap 硼酸鹽捕獲柱

The BorateTrap^™ is an in-line trap 視通column, and is recommended for黑請 optimal performan地煙ce during carbohydrate anal對水ysis.

• In-line trap column r舊東emoves borate conta鐘購mination for HPAE-PAD.

• Eliminates peak明兒 tailing for mannose, 事機fructose, and sugar alcohols re黑鐘sulting from borate contam資但ination. 

Borate contamination in eluents can ca窗湖use a significant loss of pea通事k efficiency, espec劇電ially for mannose, fruc女她tose, and reduced mon筆我osaccharides. If b男下orate is present in th的通e eluent, it binds both to the anio機門n-exchange column and to the carbohydra玩志te analytes. The carbohydrate-bor山動ate complex is less efficiently 男船eluted from the 制術anion-exchanger than is the carbohydr土得ate, resulting in peak tailing,藍北 particularly where訊什 vicinal cis hydroxyl groups are presen員湖t, such as for mannose an來嗎d sugar alcohols.&nbs喝資p;The BorateTrap eliminates peak tailin影務g for mannose, fruc快自tose, and reduced mono熱物saccharides, re街不sulting from contaminati線船on of the eluent from borate. Th線現erefore, the BorateTrap空聽 is highly recommended近美 for optimal perfo報信rmance during carbohydr數哥ate analysis.

The BorateTrap is a 4 好大;× 50從有 mm column placed between the el見弟uent pump and the inject謝喝ion valve to remov明熱e borate contamination from el的歌uents used for HPAE-PAD.&nbs上說p;Because it is placed before the inj醫和ection valve, it has no effect o能話n the efficienci劇短es or retention times of the carbohydra月頻te analytes. This column is線線 packed with a 20-μm high-訊坐capacity resin that has high s那路electivity for borate. The我雨 resin used in the BorateTrap那資 is functionalized with a polyol 視體capable of complexing borate分日 in the presence of hydroxide. Borate i美可s a known contamina市拍nt in laboratory water s見志upplies. In chr生又omatography, borate co朋跳ntamination of HPLC 訊湖eluents may be a result of degradi紅到ng deionized water systems or as l拍得eachate from borosilicate glass議北ware.
