The load terminal adopts the full-automatic matching technology independently developed by Tianrui Instruments, which has the advantages of fast matching speed and high precision, ensuring that the output power is applied to the load to the maximum extent, improving the efficiency of power supply, thereby improving the stability of the instrument and making the entire ignition process simple and convenient.

6.Advanced sampling system

The sampling system is stable and can be equipped with various atomizers and atomization chambers at home and abroad. It can be equipped with high-salt atomizers, hydrogen-fluorine-resistant atomizers, etc. to meet the various needs of customers; at the same time, Tianrui's independently developed automatic sampler makes the test operation more convenient and further improves the test efficiency.

7.Unique optical system

The medium-step grating-prism cross-dispersion method is adopted, and the professional optical optimization design maximizes the light flux while ensuring excellent spectral resolution; there is no moving optical component, which ensures good long-term stability; the ultra-low stray light design combined with the unique optical design greatly reduces the interference of background light and further improves the detection limit; the nitrogen distributed purge light chamber combined with high-quality optical components ensures the measurement of deep ultraviolet region, especially P, S, As and other elements.

8.Precise wavelength positioning

Intelligent and precise automatic wavelength calibration algorithm can measure without additional peak correction, ensuring accurate measurement while saving a lot of standard solution and measurement time.

9.Excellent performance detector

Adopt large-size CID detector, advanced, mature and stable; large target size, million-level pixels; continuous coverage of 165-900nm range, one exposure, full spectrum display; non-destructive reading (NDRO) function, improves the signal-to-noise ratio of weak analysis lines, improves the accuracy of results, and data acquisition and analysis are better than CCD; excellent linear dynamic range and inherent anti-overflow function ensure that any strong or weak spectral lines can be measured and analyzed within one exposure, while providing flexibility for the method to select the ideal wavelength (second, third or more sensitive lines can be selected to eliminate interference).

10.Ultra-fast test speed

Each analysis line can set any appropriate integration period within the exposure time to optimize the measurement; the intensity integral value of all analysis lines can be read out in one exposure to speed up the analysis; the spectral line can also be specified to read out independently, and the readout time does not exceed 2ms.
