The Defect Chemistry Analyzer aixDCA is a 4-point-measurement system for electrochemical measurements in temperature controlled pure oxygen environment.
Pure oxygen environment 1000mbar - 10e-8mbar
No carrier gases needed
Furnace temperature 25°C - 1000°C
Electrometric follower and lock-in amplifiers
Quadrupole mass analyzer
Electrical conductivity relaxation (ECR) and high-temperature equilibrium condictivity (HTEC) measurements
The pure oxygen environment inside the sample holder can supply the sample with oxygen pressures between 1000 mbar and 10e-8 mbar and temperatures form room temperature up to 1000°C without the influence of additional gases. Conductivity measurements can be realized in 4-point and in 2-point configuration using the built-in electrometric follower and lock-in amplifier. The quadrupole mass analyzer detects oxygen release from the sample and can be used as migration and permeation detector with the use of the two-compartment adapter.
