1.7 微米的CSH顆粒是沃特世第三代雜化顆粒技術(shù)?；谖痔厥?/span>BEH(亞乙基橋雜化)顆粒技術(shù)，CSH顆粒帶有低水平的表面電荷，設(shè)計(jì)在低離子強(qiáng)度流動(dòng)相條件下提高樣品載量和峰對(duì)稱性，同時(shí)仍維持BEH顆粒技術(shù)固有的機(jī)械與化學(xué)穩(wěn)定性。

ACQUITY UPLC CSH苯己基柱提供與直鏈C18柱互補(bǔ)的選擇性，特別適用于芳香性分析物。與CSH C18顆粒的化學(xué)耐受性一樣，CSH苯己基柱可在pH1-11條件下使用，可以利用低pH條件和高pH條件獲得不同的分離選擇性。

Hospital Readmission Rates Following AMI: Potential Interventions to Improve Efficiency

A sensitive method for the simultaneous analysis of vitamin A (VA), 25-hydroxyl vitamin D 3 (25-OH VD 3 ) and ±-tocopherol (VE) in children plasma by liquid chromatography-tandem mass spectrometry (LC-MS/MS) has been developed and validated. Sample preparation chose the solid phase extraction. 100L of plasma was mixed with 300L ethanol contained 4L isotope-labelled analytes. After a series operation, the supernatant was applied to the solid phase extraction (SPE) plate (HLB Elution plate). The eluate was evaporated, and reconstituted in 100L methanol. And then, 6L reconstituted sample was injected into LC-MS/MS. Quantitative analysis was carried out by multiple reaction monitoring (MRM) with a positive mode electrospray (ESi+). Separations of VA, 25-OH VD 3 and VE were performed on an Acquity UPLC reversed-phase Phenyl-Hexyl analytical column (CSH, 2.150mm, 1.7m). Gradient elution was used at a flow rate of 0.4mL/min with a phase consisting of 0.1% formic acid solution and 0.1% formic acid, 5mM ammonium formate in acetonitrile.
