The Garnet model, a Q-switched UV laser for OEM from Laser-export, is an ideal ionisation source for mass-spectrometry. The laser radiates at 355nm wavelength with a pulse energy of 20µJ at pulse repetition rates of 200-2,000Hz and pulse widths of 5ns. The laser can replace nitrogen lasers in Maldi TOF mass spectrometry systems. It is cost-effective solution with confirmed reliability and extended lifetime which offers real advantages to the user compared to the older gas laser technology. The laser comes with a 24V power supply.
