聯(lián)系我時(shí)，請(qǐng)告知來自 化工機(jī)械設(shè)備網(wǎng)*分離技術(shù)；多種鍵合相技術(shù)
2004年，分離科學(xué)由于超高效液相色譜技術(shù)（Ultra-Performance Liquid Chromatography，UPLC®）的問世而發(fā)生了巨大的革命，在儀器和色譜柱方面的顯著進(jìn)步實(shí)現(xiàn)了液相色譜在分離度、靈敏度和速度方面的巨大跨越。一體化設(shè)計(jì)的ACQUITY UPLC®系統(tǒng)和ACQUITY UPLC色譜柱允許分析人員使用亞2微米顆粒色譜柱，以滿足和克服分析試驗(yàn)室所面臨的挑戰(zhàn)，使分析科學(xué)家們更成功，業(yè)務(wù)收益更大、產(chǎn)出更多。
CSH技術(shù)的優(yōu)勢(shì)包括：
l 對(duì)于堿性化合物的*峰形
l 提高載量
l 更換流動(dòng)相pH后柱再平衡速度快
l 改善的批次之間重現(xiàn)性
l 在低pH和高pH條件下優(yōu)異的穩(wěn)定性
CSH顆粒技術(shù)也具有HPLC粒徑產(chǎn)品(2.5,3.5和5微米)，對(duì)應(yīng)于XSelectCSH HPLC柱家族，這確保在HPLC和UPLC技術(shù)平臺(tái)之間方法可無縫轉(zhuǎn)換。
ACQUITY UPLC CSH C18柱克服了大多數(shù)現(xiàn)代C18柱在低離子強(qiáng)度流動(dòng)相條件下(如0.1%甲酸體系)因載量所導(dǎo)致的峰形差問題。因帶有嚴(yán)格控制下的、低水平的正表面電荷，ACQUITY UPLC CSH C18柱為堿性化合物提供行業(yè)的峰形，而無需使用離子對(duì)試劑。
目的建立超高效液相-紫外光電二極管陣列檢測(cè)-串聯(lián)四級(jí)桿-飛行時(shí)間質(zhì)譜(UPLC-DAD/Q-TOF-MS)法分析化學(xué)成分。方法分析采用Waters ACQUITY UPLC CSH C18色譜柱(2.1 mm×100 mm,1.7μm);柱溫20℃;流動(dòng)相0.1%甲酸-0.1%甲酸乙腈,梯度洗脫;體積流量0.2 m L/min;檢測(cè)波長(zhǎng)222 nm;飛行時(shí)間質(zhì)譜,正離子掃描模式。通過對(duì)照品比對(duì),以及質(zhì)譜、光譜數(shù)據(jù)進(jìn)行分析。結(jié)果從中鑒定出19種成分,其中11種屬于黃連,8種屬于吳茱萸。結(jié)論該方法快速高效,可用于的質(zhì)量控制。
