Název v původním jazyce

Diode laser thermal vaporization inductively coupled plasma mass spectrometry for analysis of biological microsamples

Popis výsledku v původním jazyce

A new sample introduction technique to inductively coupled plasma, diode laser thermal vaporization (DLTV)1 is presented. In contrast to existing sample introduction systems based on laser ablation, the technique employs low-cost components, such as a diode laser, a simple laboratory-built chamber and common filter paper as a sample carrier. Well-defined submicroliter sample volumes are deposited on a preprinted filter paper and dried samples are vaporized in the prototype laser ablation chamber equipped with the diode laser. The diode laser power is sufficient to induce pyrolysis of the preprinted paper with deposited samples and the generated aerosol is carried out into the ICP MS. The prototype chamber design is kept as simple as possible: it is made of glass tube and equipped with a near infrared continuous-wave diode laser attached to a common syringe pump serving as a translational stage for fast line scan along the paper strip.
