| Spectrometer capacity | Simultaneous configuration: Four Multichromators (covering eight elements) Sim-seq configuration: SmartGonio + one Multichromator (covering two elements) |
| UCCO technology | Ultra Closely Coupled Optics offering largest solid angle for most efficient irradiation of the total sample surface: 50 W power providing excitation similar to 200 W or 200 W power providing excitation similar to 500 W |
| X-ray excitation | Air cooled Rh anode end window tube with thin Be window (0.075 mm). Other anodes available on request. 50 W version: Solid-state high frequency generator of maximum voltage 50 kV and maximum current 2 mA (combinations to be chosen to be at 50 W) 200 W version: maximum voltage 50 kV and maximum current 10 mA (combinations to be chosen to be at 200 W). Max. line voltage variation 230 V -15% to +10%. Stability ± 0.0002% per 1% variation |
| SmartGonio | Fully automatic, gearless, microprocessor controlled compact goniometer using optical encoders Total angle range: 0 ˚ -150 ˚ 2 θ (Flow proportional counter: 17 ˚ -150 ˚, Scintillation counter: 0 ˚- 90 ˚ ). Continuous digital scans: from 0.25 ˚/min to 327 ˚/min. |
| Multichromator | Fixed channel using dual curved crystal optics allowing analysis of two elements simultaneously. Sealed detectors available for all elements from sodium (Z=11). Flow proportional or scintillation detectors also available depending on element. Dual pulse height integration to discriminate and correct for 2nd order peaks. Note: some elements can only be fitted as single channel monochromator |
