Full automation design

The instrument is thoroughly computer-controlled except for the power switch, which is reliable, safe, and convenient.

Auto-control of gas flow

In the sample introduction system, the carrier gas, plasma gas, auxiliary gas are controlled through the advanced mass flow controller (MFC), features continuously adjustable and stable, etc., which ensures the stability of the introduction system and the foundation for the stable light source.

Peristaltic pump

A high precision 12 roller, 4 channel peristaltic pump, with speed adjustable according to the demanding, provides smooth, stable sample introduction and drain, to ensure the introduction rate consistent with the drain rate, which is adjusted as per required to stabilize the introduction system.

Precise wavelength positioning

Intelligent, precise automatic wavelength calibration algorithm, achieves the measurement without additional peaks calibration, to ensure an accurate measurement whilst saving solution and measurement time.

Fast, accurate auto-matching

The load terminals employs the full-automatic matching technology developed by Drawell, features fast matching, high precision, etc., which could achieve maximum output power, enhance power efficiency, ensure the stability of the instrument whilst facilitating ignition.

Stable, advanced solid-state RF power

The instrument employs the solid-state RF power developed by Drwell, which is compact and delivers reliable performance with the power stability and safety, to further improve the instrument’s stability and security.

Ultra-fast analysis speed

The analyst can set any suitable integration time for all the analytical lines in one exposure to achieve optimal measurement, or acquire the intensity integral value in the end of the exposure to enable the analysis faster, or specify any one or several specific line(s)to read-out(the readout time<2ms).

Superb optical system

Adopting the echelle-prism cross-dispersion type polychromator, elegant optical optimization design maximizes the flux whilst enabling the excellent spectral resolution. No movable optical components achieves unparalleled long-term stability; Ultra-low stray light design with the unique optical design greatly reduces the background interference and further improves the detection limit. A highly efficient N2 distributed purge system for the optical tank combined with the high-quality optics ensures deep UV analysis, especially P, S, As, etc..

Powerful software analysis function

Software is easy to operate and intuitive, it offers the capability with qualitative, semi-quantitative and quantitative analysis, instrument diagnostics, intelligent optimization, flexible full-spectrum research function, strong offline reprocessing, scientifically intelligence background correction and interference cancellation algorithm, which enable the analysis more professional and accurate.

Excellent performance detector

Employing the CID detector, which is advanced, mature and stable, largest-size active area, megapixel. Full-frame Imaging ability to capture the entire ICP-OES spectrum (165-900 nm) permits quantitative analysis. Non-destructive readout improves the signal-to-noise ratio of weak analyte lines and ensures the precision of results, whist enabling data acquirement and analysis faster than CCD. Excellent linear dynamic range and inherent antiblooming capability allow the measurement of weak analyte emission signals adjacent to intense emission signals, whilst providing flexibility to choose the ideal wavelength for a method (alternative secondary and tertiary lines to overcome interferences).

Advanced sample introduction system

The sample introduction system is efficient and stable, equipped with various nebulizers and spray chambers, it can also be equipped with high solids nebulizer, hydrogen fluoride-resistant nebulizer, etc.as per required. Besides, the autosampler developed by Drwell facilitates the operation, and further improves the analysis efficiency.
