Laser diode thermal desorption

Laser diode thermal desorption (LDTD) is a technique used primarily in analytical chemistry and mass spectrometry for the desorption and ionization of sample analytes. This method utilizes the focused energy from a laser diode to heat a sample material, causing the analytes to desorb from the surface of a solid or liquid matrix into the gas phase. ### Key Components of LDTD: 1. **Laser Diode**: A laser device that emits light at specific wavelengths.
