Evolution of the signal intensity as recorded in MALDI MS by analyzing the capture droplet after LADC experiment with the LADC laser energy/pulse for BK solid sample from (A) Black PVC tape and (B) high-reflectivity mirror at 532 nm.
Signal intensity corresponds to the averaged intensity of [M+H]+ signals taken over the different measurements.
