- Description
- The Turner Fairbank Highway Research centers intend to purchase on a sole source basis an XRF Energy dispersive X-ray spectrometer (Panalytical Epsilon 5) from Panalytical Instruments. This instrument will be used for the quantitative analysis of aggregates, cement, concrete, fly ash and asphalt for their metal content. Research is directed towards prevention of ASR gels in concrete, increased use of fly ash in concrete and forensic studies for State agencies. The EDXRF instrument must be capable of precise accurate non destructive analysis of powders, liquids and solids. It should be capable of analyzing elements in the periodic table from Sodium to Uranium. The instrument should be equipped with an X-ray tube capable of providing 100kV and up to 24ma to ensure excitation of heavy element K-lines up to Hf in the periodic table. The total power should not be less than 600W. The instrument must have a polarizing optical path for the reduction of spectral background. The optical path must have the capability of utilizing up to 14 secondary scattering targets for optimization of the detection of key elements in the periodic table. The instrument should be fitted with a high resolution solid state Ge detector capable of a resolution of at least 135 eV @ Mn. The detector should have an energy range of 0.7 to 100KeV, be liquid nitrogen cooled for highest resolution and be fitted with a safety sensor to automatically turn off HT to the detector in case liquid nitrogen levels fall below operating levels. The instrument should be fitted with an integral high capacity sample X-Y changer and have the capability of accommodating up to 52 samples in cups or 133 uncupped samples. The sample change must have the capability to differentiate between solid and liquid samples to prevent inadvertent loading of liquids samples in a vacuum. The sample change must also be capable of being continually added to during a batch to provide continuous uninterrupted analysis. The software should be windows based and be compatible with modern software platforms. The software should be designed for easy sample analysis and data retrieval and allow for the flexibility of application development by the user. The software should be capable of at least the following capabilities; 1. Be capable of comparing multiple spectra. 2. User control of deconvolution parameters. 3. Blank subtraction capabilities. 4. Full array of matrix correction possibilities including Alphas and Compton correction. 5. Manual and overlap spectral line correction. Panalytical is the only source known to satisfy the government’s requirements.
