Figure 5-6. Matrix enhanced surface-assisted laser desorption/ionization time-of-flight mass spectrum of angiotensin I using the poly(vinyl alcohol) substrate. An amount of 800 amol of angiotensin I was applied, and the CHCA matrix concentration was 0.1 mg/mL. The spectrum is the sum of 100 laser shots.
