Laser desorption ionization of proteins with molecular masses exceeding 10,000 daltons

Author(s): Karas M, Hillenkamp F

Abstract

In the following, the first results on ultraviolet laser desorption (UVLD) of bioorganic compounds in the mass range above 10000 daltons are reported. Strong molecular ion signals were registered by use of an organic matrix with strong absorption at the wavelength used for controlled energy deposition and soft desorption (7)
