Mineralogian laboratoriot

Tutkimuslaitteistoista keskeisimpiä ovat elektronimikroanalyysi (EPMA), röntgen pulveridiffraktometri (XRD), kokokivianalyyseihin käytettävä aallonpituusdispersiivinen röntgenfluoresenssispektrometri (WD-XRF), infrapunaspektrometri (FT-IR), pyyhkäisyelektronimikroskooppi (SEM), fluidisulkeumalaboratorio, klastisten näytteiden raekokoanalysaattori (Malvern) ja joukko erilaisia näytteenkäsittelylaboratoroita (ohuthielaboratorio, näytemurskaus, jauhatus, seulonta, jne.)

Electron probe microanalyzer or "microprobe" is designed for non-destructive micrometer-sized spot quantitative chemical analysis from polished mineral sample surfaces. We are running a completely modernized Jeol JXA-8600 superprobe equipped with five wavelength dispersive X-ray detectors (WDS) and one energy dispersive X-ray detector (EDS).

Analysis detector and sample stage control electronics of this instrument were switched to PointElectronic SAMx hardware and Diss5/IDFix software in 2009. In addition, the whole electron gun control unit of the original instrument was replaced with PointElectronic digital control in spring 2013.

Instruments:

  • EPMA JEOL JXA-8600 Superprobe with 5 WDS detectors and one Sirius SDD EDS detector, upgraded with SAMx hardware and XMAs/IDFix/Diss5 analytical software
  • SEM JEOL JSM-T330, Oxford Si(Li) EDS detector, upgraded with  XMAs/IDFix/Diss5 analytical software
