Absorptometer C: Oil absorption
The new Absorptometer C Data Acquisition System determines oil absorption in compliance with ASTM D 2414 as well as ASTM D 3493.
The Absorptometer C Data Acquisition System consists of the following major components:
- frequency inverter drive unit with precise torque measurement
- high-precision measuring mixer with special blades
- high-precision burette, variable programmable titration rate for optimum test procedure
- 64-bit software for (min.) Windows XP, Windows VISTA, Windows 7 and Windows 8
The torque is measured and recorded throughout a special mixing process: the oil is continuously added by an automated buret into the mixer. The free flowing, powdery material absorbs the liquid. This leads to agglomerate formation until saturation. During this transition, more and more torque is needed for the mixing and eventually a torque peak appears on the time-torque curve. The OAN itself is given in accordance with the standards and common practice in ml (of the absorbed oil) / 100 g (of sample material).
