Rotary Disc Electrode Atomic Emission Spectrometer which is capable of directly testing the contents of various metallic elements in liquid samples, such as lubricating oil, hydraulic oil, fuel oil

Feature & Specification

Rotary Disc Electrode Atomic Emission Spectrometer

The instrument conforms to the ASTM D6595 Standard Test Method for Determination of Wear Metals and Contaminants in Used Lubricating Oils or Used Hydraulic Fluids by Rotating Disc Electrode Atomic Emission Spectrometry and ASTM D6728 Standard Test Method for Determination of Contaminants in Gas Turbine and Diesel Engine Fuel by Rotating Disc Electrode Atomic Emission Spectrometry.
The instrument can be widely used in fields of oil quality monitoring for large equipment, such as aircrafts, warships, high-speed railways, engineering machinery, and etc. It can be applied to the monitoring of mechanical wear and fault diagnosis analysis. It is commonly applied to the field of metallic elements analysis in oil.

1. Cluster optical fiber signal transmission dual-layer, multi-CCD detection spectrum system
2. The linear array of multiple CCDS is arranged in a Roland circular shape, which realizes continuous and simultaneous detection of the whole band, and facilitates later development of other elements
3. High performance CCD detector, each CCD with 3648 pixels
4. Ultraviolet band spectral enhancement detection technology, enhances the ultraviolet band light intensity, and prolongs the life


1. It is suitable for the simultaneous determination of multiple elements of various metal elements, such as wear metals, pollutants and additives in oils
2. The standard configuration simultaneously determines 24 elements, including Ag, Al, Ba, Ca, Cd, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Sb, Si, Sn, Ti, V, Zn and Bi. Detection channels can be flexibly increased according to different needs, when adding analysis target elements, no hardware changes are required.
3. Built-in working curve
4. It is needless to pretreat the samples, direct injection, ~40s for a single test, the testing-time is adjustable, the results will be obtained after only one measurement.
5. Low cost of use, the consumable materials includes only the standard graphite disc electrodes, bar electrodes, sample cups.
6. Uses not ceramic but spectrally pure graphite material as the disc electrode.
7. Using concentrated optical fiber to ensure the resolution of the instrument.
8. The light chamber is equipped with a closed isolation heat exchanger to effectively prevent dust, water mist and oil mist from invading.
9. It includes exhaust structure, prevention of cross-contamination.
10. Neither argon gas nor cooling water is needed.
11. Integrated fully closed frame structure design, impact resistance, deformation resistance;
