Chromolith 整體柱 快速分析

2000年，默克研究開(kāi)發(fā)了整體化硅膠（monolithic Silica）,將液相色譜分離技術(shù)的發(fā)展帶入了一個(gè)嶄新的領(lǐng)域。整體化硅膠采用了不含金屬雜質(zhì)的合成硅膠材料和的“溶膠”技術(shù)制備得到，是迄今為止的色譜硅膠。

 

 

Chromolith® 填料參數(shù)

 

 

填料	孔徑	比表面積	孔體積	碳載量	PH范圍
RP-18	2μm，130Å	300m2/g	1m2/g	18.0%	2-7.5
RP-8	2μm，130Å	300m2/g	1m2/g	11.0%	2-7.5
Si	2μm，130Å	300m2/g	1m2/g	---	2-7.5

 

 

特點(diǎn)：

 

l         由于壓力低，可通過(guò)提高流速縮短分離時(shí)間

l         單支色譜柱柱效，更可串聯(lián)使用

l         整體化硅膠結(jié)構(gòu)使其永遠(yuǎn)不會(huì)“柱頭坍塌”

l         大孔結(jié)構(gòu)確保其使用壽命長(zhǎng)，抗污染能力極強(qiáng)

取代傳統(tǒng)5μm顆粒硅膠的選擇-Chromolith® Performance 100-4.6mm

 

Chromolith® Performance是您替代5μm顆粒硅膠色譜柱的。在相同的條件下，使用Chromolith® Performance，您將獲得和傳統(tǒng)5μm顆粒填料相似的分離結(jié)構(gòu)。不同的是Chromolith®的柱壓只有傳統(tǒng)5μm顆粒填料的1/4。

 

Chromolith® Performance可為您節(jié)省75%分析時(shí)間。通過(guò)簡(jiǎn)單地將流速?gòu)?/span>1ml/min提高到3ml/min，使您獲得很高的分離速度，同時(shí)分離效果并未受到影響，柱壓也大大低于5μm顆粒填料的色譜柱。如果條件允許，您甚至可以將流速提高到9ml/min。
