Product Overview
WY-9000/9500 direct-reading optical emission spectrometer for metal and alloy analysis. Vacuum optical chamber (reduces O2 absorption <200 nm) and constant-temperature control (34°C) enhance stability and detection limits for elements such as C, P and S. Software-configurable channels allow addition or modification of element channels without hardware changes. Integrated digital light source supports multiple excitation modes (spark, arc, arc-like) for major, high-concentration, trace and ultra-trace elements. Windows-based software offers full Chinese-language UI, database functions and network data transfer.

Light Source & Excitation
All-digital solid-state spark source with continuously adjustable energy and frequency. High-frequency pulsed discharge (1–100 A) enables analysis across concentration ranges. Argon-pulsing, jet ignition and automatic purge minimize contamination and improve repeatability.

Product Advantages

• High-resolution design (long focal length grating, Parabolic–Rowland/Paschen–Runge and high vacuum) to minimize spectral interference and improve sensitivity.
• Mechanically ruled gratings allow higher-order spectra and flexible wavelength selection.
• Highly integrated electronics in standardized chassis for low failure rate and simplified maintenance.
• Fast analysis with good repeatability; typical full-channel elemental analysis in ~30 seconds.
• Software database for measurement retrieval, printing and remote data transmission.
• Temperature-controlled optical components and solid-state adsorption trap to prevent oil/gas contamination, ensuring long-term stability.
• Software-configurable element channels — add or modify channels without hardware changes.
• Optimized argon delivery reduces purge time and argon consumption.
• High-performance DSP and ARM processors for ultra-fast data acquisition and real-time monitoring (temperature, vacuum, argon pressure, light source status).
• Open electrode holder and adjustable sample fixture for varied sample shapes and sizes.
