Three Features Reduce Gas Consumption by Half







            Gas Usage During Analysis and Standby Halved


               Mini Torch


                           Mini-torch is designed to have only half the cross sectional area of standard torches. Applying the same
                           high-frequency output to the smaller cross section increases the energy density per cross section. This improves the
                MINI       excitation efficiency, resulting in higher sensitivity.

                           Reducing the high-frequency output to 0.5 kW
                           and the plasma gas flow rate to about 5 L/min
                           during standby saves energy and reduces costs.   10
                           The analysis mode starts up smoothly as well,
                           which enables stable analysis.

            Reduced Startup Gas Consumption            Vacuum

                           To enable measurements of wavelengths in the vacuum UV region (below 190 nm) ICPE-9800 systems employ a
                           vacuum pump (rotary pump) to evacuate the air and remove oxygen from inside the spectrometer. This ensures a

                           shorter startup time in comparison to purge-type systems. When the pump stops, a solenoid valve automatically
                           closes to maintain the vacuum inside the spectrometer. Consequently, there is no need to worry about
                           contamination from atmospheric air flowing back into the spectrometer after the pump stops.

            Sample Introduction System Achieves Stable Analysis for         Natural Aspiration and Gravity Drain
            Long Periods of Time
            The sample introduction system incorporates a high-accuracy nebulizer for introduction
            by free aspiration and a gravity drain. Therefore, a peristaltic pump is not necessary.
            Since there is no need to worry about a reduction in the efficiency or the variability of
            introduction caused by the deterioration of the pump tube, or trouble caused by
            improper draining, stable analysis can be accomplished for long periods of time. (If you
            wish to automatically add an internal standard element, an optional peristaltic pump
            should be used.)
