Schnelle Quecksilberbestimmung im Labor
LabAnalyzer 254
Der LabAnalyzer 254 ist die perfekte Lösung für die quantitative Quecksilberbestimmung in wässrigen Lösungen und Probenaufschlüssen im Labor.
Im Unterschied zu einer normalen Multielement-AAS ist der LabAnalyzer-254 speziell für das Element Quecksilber ausgelegt und liefert deshalb Spitzenleistungen im analytischen Bereich. Durch die Verwendung einer referenzstrahlstabilisierten Hg-Niederdrucklampe in Verbindung mit modernster UV-Detektortechnik wird eine Nachweisgrenze von wenigen ppt Hg erreicht.
