The Serinus® 56 Total Sulfur (TS) analyser delivers precise and reliable performance at excellent value. It uses proven UV fluorescent radiation technology and an external thermal converter to measure TS in ambient air (LDL < 0.3 ppb, range 0 – 10 ppm). TS is measured by converting TS to SO2 using the external HTO-1000 converter and then measuring the resultant SO2 using the pulsed fluorescence technique.
