SPAS-01 arc emission spectrometer applications include:

• input inspection of raw materials and output quality control in ferrous, non-ferrous and powder metallurgy;
• tests in mining, concentration and processing industry;
• production of ultra pure materials;
• environmental protection;
• food industry;
• forensics;
• R&D etc.

The instrument consists of a spectrum excitation source based on PRIMA A arc discharge generator and a USHT-4 universal stand, a 2S36501633 spectrograph, a 24 linear CCD unit system, a control PC and a housing with operator work station.

• PRIMA A arc discharge generator features the following benefits compared to its predecessors ( DG-2, IVS-23, UGE-4):
  • user defined dependence of arc current on time;
  • current presetting without ignition of the sample;
  • no ballast resistance;
  • manual and auto operation modes;
  • 30-50 times weight reduction and 20-40 times volume reduction;
  • startup and daily maintenance free.
• Spectrograph 2S36501633:
  • the tandem design of this model is the most efficient solution for wide range high illumination spectrographs;
  • premium concave diffraction grating;
  • our know-how allows achieving virtually utmost spectral resolution performance for this class of spectroscopy instruments (from 0.007 nm within 185-330 nm range);
  • exceptional thermal stability of the settings.
• The registration system digitizes the CCD analog signals in 16-bit format and saves the output in the internal memory (the memory capacity allows storing up to 500 frames);
  • digital signal pre-processing;
  • SPAS-01 features a detection system supporting up to 24 CCD units;
  • frame accumulation time may vary within 0.004 — 60.0 range at a 0.004 s increment;
• SPAS-01 spectrometers are controlled by the latest version of WindowsXP/7/10 compatible PPM Pro software package:
  • spectrum excitation source and registration system control;
  • three user access levels for various operator skills, from routine measurements (beginner lab technician level) to creation of new and revision of the existing analytical programs (for highly skilled spectral analysts);
  • recording and visualization of spectral data with easy navigation across the spectrum, spectral line identification, etc.;
  • an extensive database on spectral lines for their identification within the spectrum and qualitative evaluation;
  • allows personified adjustment for background amount and behavior on line by line basis for signal detection net of unwanted plasma emission, which is beneficial for sensitivity and accuracy;
  • allows using several analytical lines for each analyzed element, thus delivering by default hundred and thousand fold expansion of the dynamic range concentration wise, thus delivering virtually unlimited capabilities for analyzing the maximum concentrations of impurities;
  • enabling/disabling auto adjustment for inter-element additive and multiplication effect;
  • allows adjustment for base dilution;
  • single and double point recalibration.
