Laser diode thermal desorption (LDTD) is an ionization technique that is coupled to mass spectrometry to analyze samples with atmospheric pressure chemical ionization (APCI). It uses a laser to thermally desorb analytes that are deposited on a stainless steel sheet sample holder, called LazWell.[1] The coupling of LDTD and APCI is considered to be a soft-ionization technique.[2] With LDTD-APCI, it is possible to analyze samples in forensics,[3] pharmaceuticals,[4] environment,[5] food[6] and clinical studies.[7] LDTD is suitable for small molecules[7] between 0 and 1200 Da and some peptides such as cyclosporine.[8]
