performance advantage

Fully automated design

Except for the power switch, all functions of the entire instrument are controlled by a computer, which is reliable, safe, and convenient.

peristaltic pump

The peristaltic pump is designed with twelve rotors and four channels for fully automatic operation, and the rotational speed of the peristaltic pump can be adjusted according to the required flow rate; By using a peristaltic pump to smoothly inject and remove waste liquid, the injection speed is ensured to be consistent with the waste liquid removal speed. Customers can adjust the speed as needed to ensure the stability of the injection system.

Automatic control of gas flow rate

In the injection system, the carrier gas, plasma gas, and auxiliary gas are all controlled by advanced mass flow controllers (MFCs), which have the advantages of continuously adjustable flow rate and stable flow rate, ensuring the stability of the injection system and laying a solid foundation for the stability of the light source.

Stable and advanced all solid state RF power supply

The RF power supply used in the instrument is a fully solid-state RF power supply independently developed by Tianrui Instrument, which has many advantages such as small size, high efficiency, stable output power, and various protection functions, further improving the stability and safety of the instrument.

Fast and accurate fully automatic matching function

The load terminal adopts the fully automatic matching technology independently developed by Tianrui Instrument, which has the advantages of fast matching speed and high accuracy, ensuring that the output power is maximally applied to the load, improving the efficiency of power supply, thereby enhancing the stability of the instrument, and making the entire ignition process simple and convenient.

Advanced sampling system

The injection system is efficient and stable, and can be equipped with various atomizers and atomization chambers at home and abroad. It can also be equipped with high salt atomizers, hydrogen fluoride resistant atomizers, etc., to meet various customer needs; At the same time, Tianrui's independently developed automatic sampler makes testing operations more convenient and further improves testing efficiency.

Unique and precise optical system

Adopting a mid step grating prism cross dispersion method, professional optical optimization design maximizes the luminous flux while ensuring excellent spectral resolution; No moving optical components, ensuring good long-term stability; The ultra-low stray light design combined with unique optical design greatly reduces the interference of background light and further improves the detection limit; The efficient nitrogen distributed purging chamber, combined with high-quality optical components, ensures the measurement of elements such as P, S, and As in the deep ultraviolet region.

Accurate wavelength positioning

Intelligent and precise automatic wavelength calibration algorithm enables measurement without the need for additional peak calibration, ensuring accurate measurement while saving a lot of standard solution and measurement time.

A detector with excellent performance

Adopting large-sized CID detectors, advanced, mature, and stable; Large target size, millions of pixels; Continuous coverage in the range of 165-900nm, one exposure, full spectrum display; The non-destructive reading (NDRO) function improves the signal-to-noise ratio of weak analysis lines, enhances the accuracy of results, and outperforms CCD in both data acquisition and analysis; The excellent linear dynamic range and inherent anti overflow function ensure that any strong or weak spectral line can be measured and analyzed within one exposure, while providing flexibility for selecting the ideal wavelength for the method (second, third, or higher sensitive lines can be selected to eliminate interference).

Ultra fast testing speed

Each analytical spectral line can be optimized for measurement by setting any suitable integration period within the exposure time; It can read out the intensity integral values of all analyzed spectral lines in one exposure to accelerate the analysis speed; It is also possible to specify independent readout of spectral lines, with a readout time not exceeding 2ms.

Powerful software analysis capabilities

The software is easy and intuitive to operate, with qualitative, semi quantitative, and quantitative analysis functions, instrument diagnostic optimization functions, flexible full spectrum research functions, powerful offline reprocessing functions, and scientific and intelligent background correction and interference removal algorithm functions, making testing more professional and accurate.
