and experimentation. That is why there is a constant demand for the equipment built
in IEM, including orders from research laboratories and universities in other
countries (Sweden, India). The following apparatuses are now available for
experimental work:
Wide range of hydrothermal autoclaves and externally pressurized vessels used typically at
700-800oC and pressure of up to 6-8 Kb.
Internally heated gas bombs with large internal volume (typically, 1400oC at 5-15 Kb).
Piston-cylinder apparatuses working at pressure of up to 35 kbars. The anvil-with-hole
apparatus (up to 80 Kb). Still higher pressures (up to 250 Kb) are expected to be
brought into reach as the split sphere apparatus should be launched yet in the
nearest future.
High-pressure, high-temperature viscosimeter ( up to 15 Kb), that is used to study
magmatic melts.
Combined piston-cylinder and gaseous pressure apparatus used up to 10 Kb.
Flow-through high-pressure apparatus to study metasomatic zoning and ore concentration
processes at temperatures up to 500oC and pressures up to 1.5 Kb.
High-temperature, high-pressure reaction vessel with the sampling device for studies of
hydrothermal fluid systems at 500-600oC and 1-1.5 Kb.
Deep Sea / Borehole potentiometric probe designed in pursuit of oceanological, geological
and geophysical research as well as environmental monitoring. It allows
simultaneous measurements of pH, Eh, pS2-, pCL-, pK+, pNa+, pO2, etc. at the
ocean depth of about 8000 m and a temperature of up to 250oC
Variety of high-pressure cells for measurement of X-ray scattering in liquids or for in situ
studies of hydrothermal processes (up to 550oC at 1-2 Kb and up to 8 Kb at
ambient temperature)
IR spectroscopy cells for precise measurements of absorption up to 500oC and 1-2 Kb
Non-corrosive Raman spectroscopy cells working over the range of temperatures and
pressures up to 500oC and 1-2 Kb.
Analytical Facilities
With funding of science so greatly diminished in recent years, it is getting harder to keep
the analytical instrumentation at the Institute up-to-date. Yet, our researches can
enioy opportunities presented by the automated electron microprobe, scanning
electron microscopy, wet analytical chemistry, mass spectroscopy, gas
chromatography, AAS, Moessbauer spectroscopy, IR and Raman spectroscopy, Xray
powder diffraction. Many of these fields are headed by top-level specialists,
who are constantly improving analytical techniques.
Computer Facilities
All laboratories are equipped with 386-, 486-, and Pentium-based personal computers.
There are also several Sun- and DEC-workstations for large scale computations. All
