Catalogue excerpts

ORTEC ® GammaVision®-32 V6.08 Gamma Spectrum Analysis Software • Comprehensive Gamma Spectrum Analysis for HPGe detector spectra. • Integrated control of spectroscopy hardware. • “Highly Automated” and “Highly Interactive” modes of operation. • Identification and quantification of nuclide activities by adaptable methods. • Wide array of spectral correction tools. • Extensive use of Wizards to simplify setup and calibration. • Flexible reporting to meet local requirements. • Results database to facilitate LIMS integration. • Comprehensive QA features. • Methods compliant with latest international standards. • Multi-Language support. • Support for Microsoft Windows XP and Vista. ORTEC GammaVision-32 Gamma Spectrum Analysis Software is a comprehensive, all-in-one package, for the analysis of gamma-ray spectra acquired with HPGe detectors. It represents over 25 years of evolutionary development by ORTEC scientists. Hardware control, advanced MCA display, and a suite of data analysis algorithms are integrated into one complete package. GammaVision-32 is broadly applicable to gamma spectroscopy applications. A high degree of sample automation is possible for busy counting rooms and an array of corrections is provided to deal with sample, nuclide and spectrum-related effects. The methods employed are compliant with recognized national and international standards such as ANSI/ISO/ASQ 9001:2000, ASME/NQA-1-1989, and ASME/NQA-2a-1990 and ISO/DIS 11929. In addition to automation, interactive analysis tools aid the expert spectroscopist.

3 GammaVision®-32 V6.08 Gamma Spectrum Analysis Software A choice of five different analysis approaches (described below) is provided to deal with different spectral conditions and to ensure compliance in different regulatory environments. Regulatory compliance also requires that different formalisms for the determination of detection limit (MDA) may be required. GammaVision-32 now provides a “set and forget” choice of no fewer than twelve MDA methods. (See specifications.) At its simplest, the analysis of a gamma ray spectrum involves the following distinct steps: • Peak location in a spectrum...

ENV32 is a similar approach to GAM32. It starts with a second difference peak search, removing nuclides from further analysis which, although present in the user library, may be rejected because their complete expected complement of peaks have not been judged as found. A WAN1 type analysis then proceeds. An additional industry compliant feature of this analysis method is, that if after all calculations are complete, and the activity of a nuclide is calculated as negative, this result is preserved rather than discarded. (This process is referred to as “directed fit.”) MDA values are reported for...

The nuclide library database includes the nuclide name, half-life, half-life uncertainty, and nuclide category flags (e.g., fission product, thermal neutron activation product). Additionally, GammaVision-32 provides “usage flags” such as “No MDA,” “exclude from Averaged MDA” and “key line” designations to select which lines are to be used in determining nuclide peak-averaged activity or MDA. Interactive Reanalysis Tool The interactive reanalysis mode allows the expert user to repeatedly refit the spectrum while monitoring the fit residuals. Peaks can be manually adjusted in energy and added or...

6 The GammaVision-32 Reports The product can only be as good as the output report. Standard GammaVision-32 reports are: • Flexible with user’s choice of the amount of detail. • Comprehensive, in long format, all peaks found are “dispositioned with explanatory symbols.” • Logically structured. • Text formatted for easy import to LIMS. A44-B32 Report Writer The report writer option incorporates a Microsoft Access™ database for data storage and Seagate Crystal Reports™ for reporting procedures. Crystal Reports are versatile, flexible, and can be modified to meet needs for highly customized reporting....
