Vacuum-Type Full-Spectrum Direct-Reading Spectrometer

Product Overview

The WY-9000 is a direct-reading optical emission spectrometer capable of analyzing metals and their alloying elements. It boasts excellent overall stability and is easy to commission; software-based adjustments allow users to readily modify and add channels, and even to introduce an additional analytical matrix with minimal effort.

The instrument incorporates modern optoelectronic and automation technologies, such as automatic spectral-line correction, which significantly enhances its level of automation, making operation simple and flexible. Vacuum pumping in the optical chamber minimizes O₂ absorption of spectral lines with wavelengths below 200 nm, thereby greatly improving the stability and detection limits for elements such as carbon, phosphorus, and sulfur. A high-vacuum shut-off valve is employed to prevent vacuum oil contamination from affecting the optical components within the chamber. A constant-temperature system (set at 34°C) reduces the instrument’s sensitivity to ambient temperature variations and ensures excellent long-term stability. The highly integrated, maintenance-free digital light source is a versatile composite source capable of generating multiple combined excitation modes, including sparks, arcs, and arc-like discharges, enabling the analysis of major, high-concentration, trace, ultra-trace, and even ultra-high-concentration elements. The software features a Windows-based interface with full Chinese-language display, comprehensive functionality, and user-friendly operation.

Each instrument is custom-manufactured to meet the specific requirements of the user, meticulously assembled and adjusted, and thoroughly calibrated. Therefore, the WY-9000 direct-reading optical emission spectrometer serves as a quality assurance tool for process control in metal smelting and is the preferred, ideal analytical instrument for users.

Detailed Specifications

Product Advantages

A 1,400 mm focal-length grating design, with a Parabolic–Rowland configuration and high vacuum, offers high resolution and high sensitivity. Moreover, since mechanically ruled gratings can produce higher-order spectra, wavelength selection is more flexible, thereby minimizing spectral interference.

2. The instrument features a well-optimized structural design, with an electronic system housed in an internationally standardized chassis and employing highly integrated circuitry, resulting in a low failure rate.

3. Fast analysis speed, good repeatability, and excellent stability;

4. Suitable for the analysis of a wide range of matrices: Fe, Co, Cu, Ni, Al, Pb, Mg, Zn, Sn, and others;

5. The operating software is designed for use on a pure Chinese-language Windows system, making it simple and easy to understand.

6. The computer software is equipped with a database system, facilitating the retrieval and printing of measurement data and enabling convenient and rapid remote data transmission over the network.

7. Each system is independently powered, forming modular units that are easy to use and simple to maintain;

8. The adoption of temperature-control measures for the optical components ensures the instrument’s stable operation, thereby reducing its environmental requirements.

9. Add or modify element channels simply through software settings—no additional hardware required, saving you hassle, time, and money.

10. Rapid analysis speed: complete elemental composition analysis for all channels within 30 seconds. For different sample types, by adjusting the pre-burn time and calibration lines, the instrument achieves optimal analytical performance in the shortest possible time.

11. The spectrometer’s optical system features a vacuum, temperature-controlled optical chamber; the arc flame generated during excitation is directly coupled into the vacuum chamber via lenses, enabling a straight-through optical path that eliminates optical losses, lowers the detection limit, and delivers highly accurate, reproducible, and long-term stable measurement results.

12. Automatic optical path calibration: the optical system automatically performs spectral line scanning to ensure accurate signal detection, eliminating the need for time-consuming peak-finding procedures. The instrument automatically identifies the target spectral line, compares it with the originally stored reference line to determine the drift offset, and then locates the current pixel position of the analytical line for measurement.

13. The open electrode holder design and adjustable sample holder facilitate the analysis of samples with various shapes and sizes;

14. The working curves are constructed using international standard reference materials, with preliminary calibration performed in advance. The calibration range can be extended and broadened as needed, and each curve is generated by exciting up to several dozen standard samples, with interference automatically corrected.

15. Fully digital solid-state light source with continuously adjustable energy and frequency, suitable for a wide range of materials;

16. Solid-state adsorption trap to prevent oil and gas contamination of the optical chamber, thereby enhancing long-term operational stability;

17. An optimized argon gas delivery system reduces the argon purging time during sample excitation, thereby saving argon for users; argon consumption is less than half that of conventional spectrometers.

18. High-performance DSP and ARM processors provide ultra-high-speed data acquisition and control, with automatic real-time monitoring of the operating status of modules such as the optical chamber temperature, vacuum level, argon gas pressure, light source, and excitation chamber.
