Optical System

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 are linear CCD arrays, specially mounted without blind zones, allowing to record analytical signals from the entire spectral range.

Compared to separate spectral lines measurements using photomultiplier tubes, CCD arrays provide virtually unlimited analytical capabilities for metal and alloy analysis in a single instrument.

For short wavelength elements like S, P and C, polychromator is purged with Ar or N2 with average gas consumption 0.05 L/min.

In comparison with vacuum design, purged polychromator is cheaper and more lightweight, while it is more reliable and provides similar spectroscopic characteristics of the instrument.

Sample Stand

Sample stand construction is optimized in order to reduce argon consumption. Absence of the upper housing and convenient sample clamp mechanism make it possible to analyze samples of various shape and size. Special adapters are available for thin rods and wires analysis. Spark chamber cleaning is easy and does not require any disassembling. Closed-cycle water cooling system eliminates any sample stand heating effects.

Excitation Source

Compact computer controlled low voltage spark source. Discharge current amplitude and waveform as well as pulse duration and repetition rate are adjusted in a wide range, what makes it possible to analyze various metals and alloys.

Full computer control of the generator allows to:

• Chose the optimum excitation parameters.
• Switch between different discharge modes in a single analytical exposure.
• Use programmable current peak at the discharge front.
• Automatically set up generator parameters for every analytical program.

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

Readout System

Readout system provides spectrometer control, testing and analytical signals measurements. In our spectrometers we use the most recent electronic components, thus reducing size, power consumption and heating. Due to the high speed USB interface, all the 40000 spectrum data points are transferred to the computer almost instantly.

WinCCD Software

DFS-R500 is controlled by personal computer and a user-friendly WinCCD software.

WinCCD allows to get complete control over the spectrometer, perform calibration and analysis without any special training. WinCCD contains numerous functions for spectral data processing as well as analytical tools, previously developed in our WinQuant software.

WinCCD software provides stable optical system, computer controlled excitation source and practically unlimited analytical lines selection provide good precision and long term stability of your measurements.

WinCCD Details

WinCCD is a powerful software designed for data processing and hardware control in modern atomic emission spectrometers based on multichannel CCD detectors.

WinCCD includes numerous spectral data manipulation tools as well as analytical features, previously developed in our WinQuant software. Wide functionality and flexibility make WinCCD an excellent analytical instrument, that allows to perform both qualitative and precise quantitative analysis.

WinCCD is our proprietary software, which runs on Windows 98 and more recent versions. It is continuously improved and modified, new functions are added in order to meet our customer’s requirements.

WinCCD allows autonomous operation, what is very useful for data post processing. It contains extensive spectral lines database and numerous sample spectra.

WinCCD software allows to:

• Register emission spectra in the full spectral range of the spectrometer.
• Perform qualitative analysis of unknown samples.
• Choose the most suitable analytical and reference lines.
• Take into account 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.

The distinguishing features of WinCCD are:

• Friendly and simple interface, that makes it possible to work with the program without any special training.
• Possibility to use several spectral lines for single element measurements with automatic switching from one line to another.
• Several calibration curves correction algorithms, so user can choose the most suitable one.
• Automatic control of analytical line position and automatic spectral recalibration (if necessary).
