    Spectrometrul secven\u021bial de fluorescen\u021b\u0103 de raze X (XRF) Thermo Scientific ARL PERFORM\u2019X reprezint\u0103 o platform\u0103 rapid\u0103 \u0219i precis\u0103 pentru analizarea a p\u00e2n\u0103 la 90 de elemente din aproape orice e\u0219antion solid sau lichid. Avantajele aceste tehnici analitice sunt: prepararea probei de analizat se face simplu \u0219i rapid, analiza \u00eentregii suprafe\u021be a probei, a unei por\u021biuni sau a unor puncte de pe suprafa\u021b\u0103, rapiditate \u00een analiz\u0103, stabilitate ridicat\u0103 \u0219i precizie excelent\u0103, interval dinamic larg (de la nivel de ppm p\u00e2n\u0103 la 100%).<\/span><\/p>
