MPS - 1
The MPS-1 instrument is designed for easy and comprehensive analysis of liquids by:
- Automatic temperature and concentration scans of liquid solutions and dispersions
- Simultaneous recording options of pH, viscosity, conductivity and turbidity data
- Generating quantitative and characteristic data over wide temperature-compositional ranges, useful for overview as well as for detailed investigations
- Providing an excellent basis for visualization of complex liquid state conditions
- Supplying data for phase (condition)
diagrams and multivariate analysis
Selectable MPS-1 run modes
Continuous mode: - Stepwise concentration change with intermediate heating and cooling cycles between preset temperatures limits. Continuous sampling of pH, viscosity, conductivity and turbidity data in stirred liquids. The stirring and temperature sweep rates may be varied.
Stepwise isothermal mode: - Stepwise concentration change with intermediate stepwise heating and cooling cycles. Temperature step sizes, isothermal hold time and total temperature range covered at each concentration as well as stirring and temperature sweep rates may be varied. In addition, stirring may be halted under isothermal conditions.
Reversibility – hysteresis
characteristics
Data from separate experiments as well as data from the heating and cooling
cycles in the same experimental cycle may be compared, e.g. in order to
visualize raw material variations or in order to gain insights into ongoing
solubilizing/precipitation or melting/solidifying processes, respectively,
from signal hysteresis.
The MPS-1 applications range
from basic scientific studies to the recording of characteristic phase
behavior/performance data of industrial fluids
- Phase behavior and solubility studies of liquid systems from an analysis of sampled pH, viscosity, conductivity and turbidity data
- Investigations involving liquid or solid dispersions in liquids
- Identification of critical concentrations and temperatures
- Thermodynamic data from the temperature and concentration dependence of critical phenomena
- Comparison of data, e.g. visual comparison
of graphs or differential signal graphs from the
characterization of separate batches of raw materials in liquid preparations - ……….
