Ready to Count
The Gamma Analyst is designed to get you up and running quickly, and keep you counting. All of the Gamma Analyst subsystems are designed and manufactured to exacting standards for reliability and consistent high-level performance.
The Gamma Analyst is assembled at the factory and tested to ensure all components are configured and running properly before shipment. Systems are completely setup and calibrated to count your standard samples in your geometry configurations. Calibrations are certified by a qualified Canberra analyst. Your Gamma Analyst is truly ready to count when you receive it.
We also furnish a full set of operating procedures - ready to go to work in your lab. Beyond the usual vendor documentation, the procedures present step by step instructions for your operation, not generalized instructions.
Accuracy First
Canberra's extensive experience in gamma ray spectroscopy has resulted in the most versatile, widely accepted and well-documented data reduction algorithms in the industry. Canberra algorithms deal with the most complicated problems in gamma spectroscopy. Complex multiplets, weak gamma rays on high backgrounds and peaks with poor counting statistics are no problem for the Gamma Analyst. The software automatically deals with nuclides with multiple interfering energy lines. Nuclides with important energy lines over wide energy ranges are handled with ease. Only algorithms that have been time tested can effectively cope with this variety of circumstances, and still yield high-quality, defensible assay results every time.
After your automatic assays are complete, review the really difficult spectra using our powerful interactive peak fit tools region by region and make final corrections to gain absolute confidence in the results.
The Gamma Analyst is available in two versions. The Model Gam-AN2 offers higher sensitivity (lower MDA) for low level samples or shorter count times. Model GAM-AN1 is a more economical version with somewhat lower sensitivities.
Factors affecting typical MDA values:
- MDA values presume 100% gamma abundance. To calculate MDA for a specific nuclide energy line, divide the value from the graph by the abundance at that gamma energy.
- MDA values presume sea level operation, single analyte in the sample (unless otherwise stated e.g. soil), and typical background radiation field.
- Consult Canberra for a detailed application note: "MDA Values for Samples Assayed with the Gamma Analyst"
Total System Integrity
It's not enough to have your instrument set up for first class analysis - you also have to keep it that way. You have to ensure that the instrument can't be accidentally or intentionally compromised.
Look at yesterday's gamma spectroscopy systems. They were systems covered with manual switches and knobs, each one tempting the curious passerby to touch the system - and destroy the integrity. They had computer software designs with wide open access to sensitive setup information - nuclide libraries, analysis parameter files, calibration coefficients.
Interactive peak fit helps you quickly review analysis results
Today's gamma analyst instrument is designed to protect system integrity. The electronics are 100% computer controlled, so there are no manual adjustments to compromise. Settings are accessed only via computer software - and stored with each sample for a complete record of instrument status.
Security features in the software prevent access to the sensitive setup information. For ultimate security, choose our DEC/VMS based Genie-ESP system. With Genie-ESP, even the most knowledgeable computer hacker will have a tough time getting past the tough security barriers of VMS.
Even if you choose the personal computer based Genie-PC software, you will find security protection in the application software that controls access to menu items based on the user's security level.
