Comparison of the signal intensity as recorded in MALDI MS by analyzing the capture droplet after LADC experiment for PC and BK standards at 1.4 and 2.4 mJ/pulse ablation laser energy for dried (black) and liquid (grey) preparation deposits.
Signal intensity corresponds to the averaged intensity of [M+H]+ signals taken over the different measurements.
