This method of sample preparation produces a uniform layer of very small crystals on the mass spectrometer's sample stage that are mechanically well adhered to the substrate. It is a variant of the dried droplet method. PROWL - [Read Polycrystalline thin films Sample Preparation Protocol MALDI]
This sample preparation method is a direct replacement for the dried droplet technique. It produces more uniform samples than the dried-droplet technique and the crystals are better adhered to the sample stage’s surface. MALDI Sample preparation.
