摘要：

A solution of tryptophan, rhodamine B and glycerol is irradiated in the source region of a time-of-flight mass spectrometer by visible light from a pulsed laser. Tryptophan and rhodamine B are desorbed and subsequently ionized by a second pulse of ultraviolet light. The observed mass spectra and dependence of ion yields on time delay between light pulses provide information about the laser desorption process.
