Klaus-Tschira-Labor für Kosmochemie - Noble gas analyses

• nu Instruments "Noblesse" - with resistance heated (high temperature) furnace, crushing device and laser stage heating (ESI NWR 213 UV Laser):
  for noble gas isotope analyses (He, Ne, Ar, Kr, Xe): ion detection with 8 electron multipliers and Faraday Cup.
  ​ 
  ​ 
  ​
• VG3600 (modified) - with resistance heated (high temperature) furnace, crushing device and laser stage heating (ESI NWR 213 UV Laser):
  for noble gas isotope analyses (He, Ne, Ar, Kr, Xe) and radiometric dating of minerals and rocks using the ⁴⁰Ar/³⁹Ar technique; ion detection with electron multiplier and Faraday Cup.
  ​
   
    ​​
• MAT CH5 (modified) - with resistance heated and inductively heated furnace:
  for radiometric dating of minerals and rocks using the ⁴⁰Ar/³⁹Ar and ¹²⁹I/¹²⁹Xe technique; ion source type CH5; ion detection with electron multiplier.
  ​  ​ 
• MAP 215 (modified) - with resistance heated (high temperature) furnace:
  for noble gas isotope analyses (He, Ne, Ar, Kr, Xe):ion detection with electron mltiplier.  

Microscopy

• KEYENCE VK-X200 Laser microscope - a violet laser (408 nm) allows a magnification of 200 up to 24.000 times. The maximal resolution of depth is 0.5 nm, the width resolution is 120 nm. A non-destructive investigation method to determine and analyse surface characteristics.
