SLICE – database and archiving tool for elemental analysis
|
HORIBA Jobin Yvon is the exclusive provider of SLICE software to the worldwide XRF community. SLICE (the Spectral Library Identification and Classification Explorer) is a software program developed by xk, Incorporated, in collaboration with the FBI. It is designed to archive, query and compare x-ray spectra acquired with both SEM and XRF instruments, and represents a revolutionary new approach to materials analysis. Its versatile capabilities result in reduced analysis times and improved accuracy of sample identification. With SLICE, users can create an advanced data archiving tool, allowing spectra, acquisition parameters, quantitative analysis results, text and optical images to be seamlessly linked. A subsequent database search (by keyword, composition, acquisition date, instrument parameters) allows the many thousands of spectra within the existing database to be interrogated, quickly and simply. In addition to database searching, SLICE also performs element identification and conventional quantitative analysis routines, and features a unique display capability in which spectra, displayed in linear, log, or square root scaling, can be incrementally overlapped to provide a powerful aid for visual verification. The existing database supplied with SLICE contains over 3300 spectra acquired on SEM/EDX and XRF systems. This includes main categories such as alloys (633 spectra), chemicals (248), documents (148), electronic components (147), explosives (203), firearms (327), food products (103), personal/cosmetics (348), pyrotechnics (621), biological (147) and minerals (100). SLICE is ideally suited to researchers who wish to use XRF not merely to find out what elements are present, but to answer the ultimate question in materials analysis: “what is it?”. It is a widely used tool for forensic scientists, where virtually any material can be encountered (explosive residue, paints, glass, metals/alloys, fibres), and it is now being extended to contaminant analysis in a wide range of industries, including pharmaceutical, automotive, electronics and semiconductor. |
