采用反相技術(shù)進(jìn)行分離，組成復(fù)雜的待分離粗品經(jīng)常需要用強(qiáng)溶劑如DMSO進(jìn)行溶解，由于粗品在流動(dòng)相中的溶解度低，加上大體積純有機(jī)溶劑進(jìn)樣對(duì)制備柱產(chǎn)生的壓力沖擊，是導(dǎo)致制備柱過(guò)早失效和柱床塌陷的主要因素。OBD制備柱具有的柱床穩(wěn)定性，根本不會(huì)塌陷，而且柱與柱間性能，使用壽命大大延長(zhǎng)，從而降低了使用成本。

Symmetry半制備柱與制備柱

裝填技術(shù)與柱硬件對(duì)性能的影響

實(shí)驗(yàn)室規(guī)模的HP LC分離純化對(duì)色譜工作者提出了諸多挑戰(zhàn)，其中一個(gè)zui大的挑戰(zhàn)是制備色譜柱本身。由于柱與柱之間在性能和使用壽命上的不性，常常導(dǎo)致樣品損失、重復(fù)純化操作以及從小體積柱到大體積柱的放大能力差。沃特世科學(xué)家意識(shí)到這個(gè)問(wèn)題的存在，歷經(jīng)三年，研究了裝填工藝過(guò)程中的所有因素以及柱設(shè)計(jì)本身。在此基礎(chǔ)上，沃特世公司于2003年推出了技術(shù)OBDTM(Optimum Bed Density，柱床密度)應(yīng)用于沃特世制備柱產(chǎn)品。(UK號(hào) # GB2408469)。

問(wèn)題的根本原因就是在于，制備柱的柱床裝填必須足夠致密，才能在使用過(guò)程中能夠承受流動(dòng)相壓力而仍保持穩(wěn)定的柱床狀態(tài)。傳統(tǒng)的勻漿裝填方法，用于分析柱規(guī)格時(shí)能夠產(chǎn)生必需的柱床密度；但是當(dāng)用于制備柱并使用較小粒徑填充制備柱時(shí)，隨著柱內(nèi)徑與長(zhǎng)度的增加，就越來(lái)越難以達(dá)到柱使用仍能保持穩(wěn)定耐受時(shí)所必需的柱床密度。柱床密度的優(yōu)化，取決于色譜填料的特定性質(zhì)與所采用的柱設(shè)計(jì)。

waters Symmetry制備柱可直接放大——準(zhǔn)確可靠地表現(xiàn)分析柱的分離效果

純化工作者大都遇到這樣的情況；即使使用和分析柱相同的填料顆粒，色譜分離往往也不能“直接放大”，總是會(huì)出現(xiàn)分離度降低或上樣量下降的問(wèn)題。

OBD制備柱的柱床密度與分析柱相當(dāng)，具有優(yōu)異的穩(wěn)定性、重現(xiàn)性和柱效，能夠保證分離的直接放大，并避免在制備分離時(shí)重新開(kāi)發(fā)方法。

更長(zhǎng)和可預(yù)測(cè)的制備柱壽命

采用反相技術(shù)進(jìn)行分離，組成復(fù)雜的待分離粗品經(jīng)常需要用強(qiáng)溶劑如DMSO進(jìn)行溶解，由于粗品在流動(dòng)相中的溶解度低，加上大體積純有機(jī)溶劑進(jìn)樣對(duì)制備柱產(chǎn)生的壓力沖擊，是導(dǎo)致制備柱過(guò)早失效和柱床塌陷的主要因素。

OBD制備柱具有的柱床穩(wěn)定性，根本不會(huì)塌陷，而且柱與柱間性能，使用壽命大大延長(zhǎng)，從而降低了使用成本。
