FEI has announced the availability of an all-new software package known as the microValidator. This unique software is designed to deliver rapid validation of FEI's scanning electron microscope (SEM) and X-Ray Microanalysis (EDS) systems used for automated particle and phase search analysis. Such applications are utilized to study gun shot residue (GSR) and for mineral liberation analysis (MLA) in the forensics and mining industries, respectively.
The microValidator aims to provide fast, automatic, standards-based confirmation of imaging and analytical performance that is critical in establishing the accuracy, traceability, and reproducibility of results. Forensic applications require validation to substantiate the evidentiary value of GSR analysis, while the mining industry often bases major investment decisions on MLA results. The package includes software, an integrated beam current meter, and a new sub-stage mount containing essential standards. All standards are certified and each one is serialized, fully characterized and documented.
The standards block of the microValidator can also be fitted with customers' own GSR proficiency test samples that can then be launched automatically to validate performance and check for measurement accuracy. The highly automated procedure enables reproducibility and encourages frequent use.
The microValidator offers three levels of automated testing: SEM, EDS and combined SEM/EDS checks. Upon completion of selected tests the system generates a report showing that all functions are operating correctly or which functions have failed. The program is also designed to differentiate between user-correctable errors and service-related errors. If all selected tests pass, users can show that system performance has been validated objectively.
The microValidator software is compatible with EDAX and Bruker X-ray microanalysis systems.
