The method includes three steps, procedure of two points prediction, procedure of validation by multiple points regression and sequential matching. The tR of compounds on a HPLC column can be calculated by standard retention time and linear relationship. Results The method was validated in two ...
Nanospray LC/MS is well established as state-of-the-art technology because of its high sensitivity and low sample consumption. It is most often used for applications with limited sample amounts or when there is a need for analysis of trace level components in complex mixtures.Although nanospray...
