Laser desorption of ions from microscopically rough surfaces, novel technique for ultrahigh sensitivity detection of organic and bioorganic compounds

摘要

Surface-Assisted Laser Desorption Ionization (SALDI) has been developed for the ultra sensitive detection of gas-phase organic compounds. This novel method is characterized by high sensitivity and selectivity. The method may be realized in a comparatively simple, affordable, and highly efficient instrument for on-line trace detection of such practically important compounds as: 1. narcotics; 2. biomolecules, 3. explosives.
