XRF - Philips Magix Pro
| The Philips Magix Pro's main function of the XRF will be for
routine major, trace, and limited rare-earth element analysis of rocks,
soils, ores, brines, and oils. The sequential spectrometer is designed for
fast, high precision, qualitative and quantitative elemental analysis.
Samples can be run as fused glass discs, loose or pressed powders, or
liquids. Sample preparation facilities are available for fused discs and
pressed pellets. Preparation and calibration of standards is required for
quantitative analysis; while qualitative analysis is possible with the
standardless software.

The Philips Magix Pro wavelength dispersive sequential X-ray spectrometer system is equipped with a 4kW light element super sharp RH target end window X-ray tube, close-coupled optics for maximum signal strength, a full set of analyzer crystals for the analysis of elements in the range of O-U, 3 detectors (a flow and a sealed proportional detector in tandem, plus a scintillation detector in parallel), a range of beam filters and collimators, vacuum operation for the analysis of solids, helium environment for liquids and loose powders, a 4kW/ 125mA solid state X-ray generator, automatic sample changer set up to handle 60 samples but capable of 168 samples. The system utilizes the Philips SuperQ Data Collection and Evaluation Software, v3.0; the IQ+ Standardless Analysis Software; and ProTrace. |
| Sample preparation for the XRF includes the HD Elektroniks VAA2 automatic fuser with platinum crucibles and molds for the fused glass discs. The Spex Certiprep press model 3264B is used with a 40mm die assembly for pressed pellets. Also avaible is a muffle furnace for loss on ignition determinations at 1000 C. |
