Spectrometry software

Basic spectrometry software allows to:

• Execute spectra acquisition for the set period of time, select regions of interest and examine them on a separate plane, increasing or reducing scale on horizontal and vertical axis;
• Execute power calibration of spectra on two known energies;
• Determine centroids and area of peaks with background deduction and without background deduction;
• Carry out an automatic serial spectra acquisition with automatic record on a disk;
• Mark and select with color peaks or regions of interest;
• Move a marker on a spectrum or regions of interests;
• Make an estimation of energy resolution at one second and one tenth height of full absorption peak;
• Print out spectrum window;
• Transfer spectra to a software for spectral lines identification and elements concentrations determination.

Data analysis software (operation from Notebook) allows to:

• Identify elements according to position of spectral lines using library of X-ray K, L and M series, automatic identification of elements;
• Concentration calibration using standard samples;
• Use spectra of pure elements for precise description of spectral lines during approximation;
• Precise calculate background and net peak areas.
