  • MALDI plate and process for making a MALDI plate
    Patent number: 6900061
    Abstract: A sample plate for a MALDI process is provided which comprises an electrically conductive substrate having a hydrophobic coating whose thickness and hydrophobic character can be modified by changing the coating substrate and/or the concentration of the substrate. Different coating substances that have provided optimal performance of the sample plate for reproducible deposition and analysis by MALDI-MS and MALDI-MS/MS processes of analyte mixtures include synthetic waxes such as paraffin compositions, lipids, organic acids, silicon-containing compounds, silica polymers and natural waxes. Metal polishes that have been used to clean and regenerate plate surfaces have also provided a sample plate that has optimal performance for reproducible deposition and analysis by MALDI-MS and MALDI-MS/MS processes of analyte mixtures.
