Diode laser thermal vaporization inductively coupled plasma mass spectrometry for determination of trace elements in microsamples
Original language description
A new method for determination of trace elements in submicroliter sample volumes using diode laser thermal vaporization inductively coupled mass spectrometry (DLTV ICP MS) is presented.(1) Common laser-based sample introduction methods use an expensive high-energy pulse laser, whereas DLTV employs a low-cost near infrared continuous-wave diode laser. The diode laser energy is sufficient to induce pyrolysis of the preprinted paper with depositing micro-volume samples and the generated aerosol is carriedout into the ICP MS and tested. The limits of detection of Co, Ni, Zn, Mo, Cd, Sn and Pb deposited on the preprinted paper were found to be in the range of 4 ? 300 pg. The technique was applied to determination of lead in whole blood and tin in canned food without any sample treatment. Selection of optimal conditions, experimental arrangement, raster, scan speed etc. will be discussed.
