Short summary
Laser desorption of individual particles prior to ionization is the key to reveal their organic composition. The CO2 lasers required are bulky and maintenance-intensive, limiting their use in the field. We have developed a compact solid-state IR laser that is easily aligned with the particle beam. Mass spectra and hit rates are similar to those of the CO2 laser. For combined characterization of organic and inorganic particle compositions, both lasers are superior to conventional single UV pulses.
