  高壓系統

  High pressure modification

  High temperature resistant stainless steel by special order. Such tubes can be used for above-atmospheric pressures, as standalone outer enclosing tubes, or as a safety container around a ceramic enclosing tube when this is subjected to above-atmospheric pressures or explosive/toxic/corrosive gases that must not escape in case of breakage of the ceramic tube. 

  The tube is made of the alloy 253 MA. This alloy has good oxidation resistance to 1100°C in dry air.

  基本系統

  Base Unit System

  The base unit alone is an option for those who want to make their own accessories and connections from scratch and /or need to reach ultimate low-cost. It may also serve those who want to equip an earlier package with one more unit to increase measurement throughput and make better use of all accessories.

  內部加熱

  Internal heater

  There are two ways of creating a temperature gradient across the length of a standard bar sample. The simple way is to move the sample slightly away from the center of the hot zone in the furnace. Another possibility is to install an internal heater. The first method is the most common way to do it and is a reliable method as long as you wait until the conditions have stabilized before doing the measurements. An internal heater can be bought separately either with or without a power supply.

  交流阻抗架構

  ACIS System

  ProboStat™ ACIS is a sample holder dedicated for AC conductivity measurements and 2-electrode impedance spectroscopy on small disk samples at high temperatures and under controlled atmospheres. Special design of the hot-zone parts facilitates mounting and replacement of test samples compared with the standard ProboStat™ furnishment. The test sample rests in a support tube, is contacted by electrode connects, and held stably in place with a spring load assembly. The setup is assembled in a single chamber mode and can be fed with virtually any gas. The sample holder is designed to operate at near-atmospheric pressure, but can be pumped to low vacuum, or hold up to 15 bar. Electrical connections are made via standard coax cables.

  催化膜系統

  ProboStat CMR - Catalytic Membrane Reactor

  Dense ceramic or metallic as well as microporous ceramic membranes find potential applications for separating oxygen from air, hydrogen from syngas, and CO2 from flue gas, all of importance in various energy technologies for reduced CO2 emissions from use of fossil fuels. In addition they may be applied in oxidation/reduction or hydrogenation/dehydrogenation processes. They may be used as a standalone membrane (membrane reactor, MR) or in intimate combination with a catalyst (catalytic membrane reactor, CMR). In the latter, the membrane may effectively remove or add a reactant, shifting the thermodynamic equilibrium and thereby the yield and/or selectivity.

  各式燃料電池樣品

  Samples for training

  Samples for training

  The samples are disks with 0, 1, 2, or 3 Pt electrodes or bars without electrodes or with Pt end-face electrodes. The electrodes are made with commercial Pt-pastes and may have Pt mesh embedded. The samples are uniaxially cold-pressed and subsequently sintered to >90% density. The ceramic powders are mostly commercial state-of-the-art supplies or spray-pyrolyzed.
