Abstract
Disclosed herein is a sample preparation plate used to prepare a sample for mass spectrometry. In particular, a sample plate used to concentrate a sample as well as remove contaminants from the sample while providing easy manipulation of small liquid droplets on a surface with minimal sample loss.
Claims12
A device for the presentation of samples for mass spectrometry analysis comprising:
- a substrate, said substrate forming a platform and one or more wells for receiving a fluid sample, said one or more wells having a wall region and a basal region,
- wherein said wall region is hydrophobic and said basal region is hydrophilic.
A method of preparing a sample for mass spectrometric analysis comprising the steps of:
- providing a substrate, said substrate forming a platform and one or more wells for receiving a fluid sample, said one or more wells having a wall region and a basal region, where said wall region is hydrophobic and said basal region is hydrophilic;
- applying a liquid sample material to a well within said sample plate;
- and,
- drying said sample such that residual sample material is concentrated within said well.
