A new single-pump four-channel sampling and waste discharge system is adopted to shorten the length of the pipeline and enhance the stability of the reaction, which can realize the switching between continuous sampling and intermittent sampling.
Three channels and three elements can be measured at the same time, which improves the analysis efficiency of the instrument.
Light source system: The high-performance hollow cathode lamp adopts the pulse modulation/constant current drive power supply mode, which improves the emission intensity and efficiency of the hollow cathode lamp and prolongs the life of the hollow cathode lamp.
The high-performance hollow cathode lamp adopts unique coding technology, the instrument can automatically identify the hollow cathode lamp, and at the same time, it can record the usage time of the cathode lamp to effectively monitor the use of the instrument.
Detection system: Hamamatsu sun-blind photomultiplier tube is used, which has the characteristics of high signal-to-noise ratio and stable performance.
The optical path adopts a shielded short focal length optical path, which effectively reduces the energy loss during transmission.
The closed double-layer quartz atomizer is adopted, and the atomization temperature can be adjusted, which can effectively reduce the liquid phase interference, reduce the memory effect, and improve the atomization efficiency at the same time.
The hydrogen flame observation window can observe the flame combustion state in real time.
The software can carry out statistics on the data, which is convenient for users to meet the needs of data statistics.
The host of the instrument can be upgraded for morphological analysis.
