SiLi Spectrometer with Peltier Cooling SOL-XE/M

X–ray Spectrometer based on Si(Li) detector with Peltier Cooling, model Sol-XEM is intended for conversion of X-ray photon energy into electrical signals, its amplification and analog filtration.

Spectrometer provides following functions:

Accumulation and processing of X-ray spectra and spectra visualization on PC display. It gives possibility to

• perform quantitative analysis of concentration of elements in the sample  using XRF methods
• make calibration of diffractometric scale in several minutes
• Establish “window” in which information is collected for establishment of diffractometric spectra, cut of background pulses and Ka spectral line from Kb spectral line of given elements. Number of outputs at least 5. The window in which may be mounted on any place in the spectrum with width 1….. 8000. 1 output can be adjusted to obtain a linear dependence of the counting rate in the window equal to the input count rate up to 200000 pulse/sec.

From WinCRM output measure intensity of spectral lines with background deduction with width of < 300 eV; it provides possibility to work without graphite monochromator and therefore increase count rates in dozens time. This option also leads to possibility to decrease X-ray tube power that is sufficient for powder samples.

The software for spectrometer emulation allows:

• to execute spectra acquisition for the set time
• to mark and select  regions of interest and examine them on a separate plane, increasing or reducing scale on horizontal and vertical
• to execute energy calibration of spectra on two known energies
• to determine centroids and area of peaks with background deduction and without background deduction
• to carry out an automatic serial spectra acquisition with automatic record on a disk
• to select regions of interest
• to move a marker on a spectrum or interesting areas
• to make an estimation of energy resolution at one second and one tenth height of full absorption peak
• to print out spectrum window
