Maldi matrix nedc

WebIn this work, NEDC 30 and 1,5-DAN compounds were chosen as matrix candidate for performance evaluation. Firstly, MALDI mass spectra were collected for the two matrices. Compared to 1,5-DAN, NEDC showed almost no interferences in both two m/z ranges of 147.00 to 148.00 and 152.02 to 152.05 (Figure S1). WebThe matrix assisted laser desorption/ionization technique is on the horns of a dilemma of metal analysis as the conventional matrixes have high background in Jump to main …
