ChemRheo
On
the basis of results from kinetic analysis of both DSC data
and rheometric data, the temperature dependence
and kinetics of viscosity is analyzed. The relation between degree
of reaction and viscosity is described by various functions.
Thermal
Simulations
A program for simulation of the thermal
behavior under conditions of both heat generation and heat conductivity.
A finite element solution for simple geometries such as infinite
plate,
infinite cylinder and sphere is offered.
The temperature dependence of cp,
density and heat conductivity is taken into account.
Peak
Separation
This program allows the separation
of overlapped peaks, using the profiles from the following peak types:
Gaussian, Cauchy, Pseudo-Voigt (additive mixture of Gaussian and Cauchy),
Fraser-Suzuki (asymmetric Gaussian), and Pearson.
Purity
Determination
Determination
of purity on the basis of the DSC-melting peak. The calculation
is carried out without any
simplification of Van`t Hoff´s equation. The adjustment of thermal
resistance on the basis of purity determination of a pure metal
itself
increases the reliability of values of high purity.
Density
Determination
This program allows the determination
of density of materials, which are melting at high temperatures on
the basis of dilatometric measurements. For this reason the sample
is positioned in a container (sapphire, graphite, quartz). Below
the melting temperature the density is calculated on the assumption of
an isotropic material. Above the melting temperature all influences
of the container, of limited precision of sample preparation are taken
into account.
DSC/DTA
Corrections
This program
allows the deconvolution of DSC and DTA curves regarding the
time constant(s)
and the thermal resistance. The time behavior of the system
is described by a series of exponential functions. The real values
are determined on the basis of the melting
peak of a pure metal.
