Symmetry色譜柱顯示出跨越多年的z越重現(xiàn)性,這來(lái)自于高純度硅膠顆粒、以及色譜柱行業(yè)內(nèi)最嚴(yán)格的生產(chǎn)工藝與指標(biāo)控制。
沒(méi)有其它硅膠色譜柱,能夠達(dá)到Symmetry色譜柱的柱與柱間、批與批間的重現(xiàn)性。
■ Symmetry C18 和 C8 色譜柱,提供z大程度的重現(xiàn)性
■ Symmetry Shield RP18 和 RP8 色譜柱,提供z越峰形
■ Symmetry 300 C18 和 C4 色譜柱,為肽與蛋白分析提供更好的峰形與回收率
1、杰出的峰形
當(dāng)需要對(duì)堿性化合物分析獲得z越峰形時(shí),SymmetryShield色譜柱是極好的選擇。該反相色譜柱基于沃特世z利內(nèi)嵌極性基團(tuán)
技術(shù),這項(xiàng)技術(shù)確實(shí)能夠“屏蔽”(shield,英文有“護(hù)罩”、“屏蔽”的含義)硅膠表面的殘留硅醇基,使它不能與堿性較大的化合物發(fā)生
拖尾作用。因此,SymmetryShield色譜柱能夠:
■ pH2-8范圍內(nèi)使峰形與分離度顯著改善(通??色@得USP拖尾因子不超過(guò)1.2)
■ 與常規(guī)C18和C8柱相比,對(duì)堿性化合物的保留較小
2、獨(dú)特選擇性
SymmetryShield色譜柱,與常規(guī)C18和C8柱相比,因?yàn)楣璐蓟钚暂^低,對(duì)于堿性化合物的保留也就較弱,從而呈現(xiàn)出不同的
選擇性??勺鳛榉椒ㄩ_(kāi)發(fā)工具。
3、完美兼容高水相條件
SymmetryShield色譜柱還特別適用于那些要求使用低比例有機(jī)溶劑、高比例水溶液的反相條件。具有內(nèi)嵌極性基團(tuán)的反相顆粒
能夠完全被水浸潤(rùn),從而確保顆粒與樣品之間的更好的相互作用。從而在高水相流動(dòng)相條件下獲得穩(wěn)定的保留,以及杰出的峰形。
