Abstract:
1. A method of analyzing samples by mass spectroscopic analysis comprising providing a surface with hydrophilic and/or oleophilic regions, which are respectively completely surrounded by ultraphobic regions, on which the contact angle of a water and/or oil droplet, which lies on this surface, is less than 120° and the roll off angle of a water and/or oil droplet with a volume of 10 μl exceeds 10° and which is respectively surrounded by ultraphobic regions on which the contact angle of a water and/or oil droplet, which lies on this surface is more than 150° and the roll off angle of a water and/or oil droplet with a volume of 10 μl does not exceed 10°, applying a sample on the surface, which sample comprises a solvent, and analyzing the sample with a mass spectrometer.
