The MFS-R11 is intended for the analysis of products of wear of engines and other mechanisms in lubricated oils.

The analysis of various oils allows users to diagnose the state of engines, reducers, transmission, hydraulic systems in the railway & motor transport, in aircrafts, etc.

The advantage of this spectrometer, lets its user to register all spectrum of the analyzed sample. This allows users to quickly find out new inclusions and impurity besides analysis of in advance certain elements.

*No purge using argon is required for operation.

(You can find technical specification & software details, down below.)

Optical System

The optical system is a well-proven 500 mm Paschen-Runge. In order to ensure spatial stability of the spectrum, all the optical elements are installed on a stable platform.Light detectors

The light detectors are represented by linear CCD detectors, mounted so as to prevent any blind zones, and allowing the analytical signals to be recorded over the entire spectral range. Compared to the separate spectral line measurements using the photomultiplier tubes, the CCD arrays combine virtually unlimited analytical capabilities in a single instrument.

Sample Stand


MFS-R11 is equipped with a special-purposed sample stand devoted for analysis of wear debris contained in various machine oils. This type of diagnostics provides determination of the mechanical conditions of engines, reducers, transmissions, etc. The liquid oil samples are taken into the analytical discharge gap using a special rotating quartz disk. The disk rotating speed can be regulated according to the oil viscosity. No purge using argon is required for operation.

Excitation Source

The digital controlled low-voltage spark source. The discharge current amplitude and its waveform, as well as the pulse duration and repetition rate are adjusted over a wide range, making it possible to analyse oils, various metallic, alloys and other materials and non-metallic samples.

The complete computerized control of the generator makes it possible to:

  • Choose the optimum excitation parameters (discharge pulse current form and frequency).
  • Switch between different discharge modes in a single analytical exposure (one can use up to 5 different modes including the High Energy PreSparking – HEPS).
  • Perform additional discharge front sharpening.
  • Automatically set up the generator parameters for each analytical program.

All these features improve accuracy and precision of the analysis and advance performance of the spectrometer.

Readout System

The readout system supports spectrometer control, testing and measurement of the analytical signals. The spectrometer has the most modern electronic components, thus it has reduced size, power consumption and heating requirements. Due to the high speed USB interface, all 40,000 spectrum data points can be transferred to the computer almost instantly.

WinCCD Software

WinCCD is designed for data processing & hardware control in modern atomic emission spectrometers based on multi-channel CCD detectors. WinCCD includes numerous spectral data manipulation tools as well as analytical features, previously developed in our WinQuant software.

Wide functionality & flexibility make WinCCD an excellent analytical instrument that allows both qualitative and precise quantitative analysis to be performed. WinCCD allows autonomous operation, which is very useful for data post processing. It contains extensive spectral lines database and numerous sample spectra.

WinCCD software makes it possible to:

  • Register emission spectra in the full spectral range of the spectrometer.
  • Perform qualitative analysis of unknown samples.
  • Choose the most suitable analytical & reference lines.
  • Take into account the spectral interference with the background and nearby lines.
  • Make calibration curves in normal and log scale, taking into account inter-element interference effects and base concentration depletion in high-alloys.

WinCCD boasts the following distinguished features:

  • Friendly and simple interface requiring no special training for working with the program.
  • Possibility to use several spectral lines for single element measurements with automatic switching from one line to another.
  • Several calibration curve correction algorithms for the user to select from.
  • Automatic control of analytical line position and automatic spectral recalibration (if necessary).

Reliable, stable, multi-purpose spectrometer for a broad spectrum of analytical tasks of engines and other mechanisms diagnostics and elemental analysis.
