The present invention enhances the laser desorption of biological molecular ions from surfaces by creating a surface localized MALDI particle matrix by ion implantation of low energy ionized clusters or chemically derivatized clusters into the near surface region of the sample. The emergency data message may be accompanied by an origination address and destination address indicative of an emergency network address. Then, with respect to 100 parts by mass of the rubber components, ethylene thiourea is added in an amount of 0. An inner tube is telescopically nested in the outer tube.
