Evolution of the signal intensity as recorded in MALDI MS by analyzing the capture droplet after LADC experiment with the ablation laser energy/pulse from glass slide (black) versus stainless steel (red) substrate for (A) BK solid sample, (B) BK liquid sample and (C) PC liquid sample.
Signal intensity corresponds to the averaged intensity of [M+H]+ signals taken over the different measurements.
