    Comparison of double-pulse and single-pulse laser-induced breakdown spectroscopy techniques in the analysis of powdered samples of silicate raw materials for brick-and-tile industry

  • Original language description

    Single- and double-pulse laser-induced breakdown spectroscopy techniques applied to the analysis of pressed pellets of silicate raw materials were compared in terms of precision, sensitivity and limits of detection. Two Nd:YAG lasers (1064 and 532 mm) inan orthogonal configuration with a reheating arrangement have been employed. The main factors influencing system performance were optimized, i.e. laser pulse energies and interpulse separation. The behaviour of plasma temperature was studied over a period of time and calibration curves for Mg were constructed for both the single and double-pulse setup. When comparing the single- and double-pulse techniques, limits of detection of Si and Mg for the double-pulse technique were found to be 10 times lower.

    Srovnání double-pulse a single-pulse techniky spektroskopie laserem buzeného plazmatu v analýze práškových vzorků silikátových surovin pro průmysl keramiky a stavebních hmot

  • Czech description

    "Single- a double pulse" techniky spektroskopie laserem buzeného plazmatu byly srovnávány v aplikaci zaměřené na analýzu práškových vzorků silikátů pro keramický a cihlářský průmysl. Byly použity 2 Nd:YAG lasery (1064 nm a 532 nm) v ortogonální konfiguraci s uspořádáním "reheating". Byly optimalizovány podmínky (energie pulsů a zpoždění mezi pulsy). Vzorky byly lisovány do tablet. Byla studována teplota plazmatu, přesnost, správnost, citlivost a meze detekce vybraných prvků. Kalibrační závislosti pro hořčík byly srovnány pro režim "single pulse" a "double pulse".
