Hilic-uplc法

WebHILIC has been referenced as one of possible approaches. However, there is a lack of experimental evidence in scientific literature so far. Methodology: Matrix effects were evaluated using spiked serum samples after SPE and protein precipitation prior to UHPLC-ESI-MS/MS. Chromatography was performed in both HILIC and reversed-phase mode. The … Web从图4可以看出，在hilic柱上的响应比在rplc柱上的响应高出十倍左右。 hilic柱使用70%的乙腈水溶液平衡。 2.hilic柱如何保存？ hilic柱使用90%的乙腈水溶液保存。 1.一直使用waters的hilic较多，感觉质量还行，但是要小心waters的hilic是分两种类型的填料的beh hilic和hilic。
