Thermoanalytical Characterization
of Pharmaceuticals
The NETZSCH Annual 2000 is based on
decades of experience of the renowned specialists Dr. E. Marti, Solvias
AG (former Novartis), Basle / Switzerland, and Prof. Dr. W.-Y. Ma, Shanghai
Institute of Pharmaceutical Industry, Shanghai / P.R.C., in the fields
of Pharmaceutical Research and Technology, as well as E. Kaisersberger
and Dr. G. Kaiser, Netzsch ìThermal Analysis Applicationsî,
NETZSCH-Ger‰tebau GmbH, Selb / Germany.
Selected examples of drug substances and excipients are outlined in
this workbook, which is based on thermoanalytical measurements using
DSC, thermobalance, TG-FTIR, TG-DSC-MS and c-DTA.
Each substance is introduced by literature data and pharmaceutical use.
Special attention having been paid to the presentation of easily understandable
experimental results.
In addition, the collected experimental facts have been evaluated by
different software programs. Routines have been applied for the determination
of melting points, enthalpy of fusion and crystallization, dehydration,
purity, kinetic data, Gibbs free energy function, melting range and
molten fraction. The importance of gas analysis by FTIR and mass spectrometry
has been underlined.
The results obtained with the performed investigations are brought into
the context of thermodynamics, physical chemistry and solid-state or
material sciences.

NETZSCH Annuals for Science and Industry
-
The Guide for Practicians
Thermal
analysis is an indispensable tool in polymer technology. Manufacturers,
processors and users employ the methods for material development and
quality assurance through control of raw materials and goods received,
process optimization and failure analysis.
Valuable tips, numerous application
examples, clear tables with characteristic material data and relevant
standards are compiled in this series of annuals for everyday use in
the laboratory. The volumes, which are the result of the many years
of experience of the Polymer Applications Laboratory, NETZSCH-Geraetebau
GmbH and the Fachhochschule Wuerzburg-Schweinfurt-Aschaffenburg, complement
one another with respect to the materials investigated and the methods
used (DSC, TG, DMA, TMA).
The team of authors is especially pleased
about the response to the annuals in the form of letters and discussions
from our large circle of readers and users on the most varied topics
of thermal analysis.
You too can use these "recipes" for your routine laboratory tasks!

Focus on:
Thermal
Analysis
for
Paints
S. Knappe, H. Möhler,
J. Opfermann, H. Walter
|
| Is the
paint already cured? How many and which solvents are still contained
in the paint? Which emissions occur in the applied temperature
range? Why can the paint be applied better by the competitor?
Why does the painted part break?
Such different questions must
frequently be answered for the development of paints. Conventional
tests are often only single-point measurements and therefore not
sufficient. In order to better understand the most complex influences,
more comprehensive analyses are highly demanded.
The proven thermoanalytical methods
in polymer technology according to DIN 51005 or ASTM E 472 offer
an excellent tool. The NETZSCH applications volume Focus on Thermal
Analysis for Paints was released in cooperation with the University
of Applied Sciences Würzburg-Schweinfurt, Department of Plastics
and Rubber Engineering, featuring the wide range of application
with practical examples from industry. With the help of DMA (Dynamic
Mechanical Analysis) investigations of clear and soft coats as
well as paint structures are presented. Solvents and decomposition
products of hydro clear coats and soft coats are identified by
using TG-FTIR (Thermogravimetry with Fourier Transform Infrared
Spectroscopy). Main emphasis was put on describing the curing
behavior of powder paints by means of DSC (Differential Scanning
Calorimetry). These results were kinetically analyzed and simulated,
together with rheometer measurements, with the new software package
ChemRheo® regarding practice-related temperature profiles.
This will not only support developers and users in the field of
paints, but will also give them new ideas for their daily work.

Focus on:
Thermal Analysis
for Polymers
H. Möhler, S.Knappe |
|
The status of thermal analysis
in polymer technology has clearly risen internationally over the
past ten to fifteen years. In particular, DSC (Differential Scanning
Calorimetry) has long been successfully applied in routine testing
of goods received, quality control and quality assurance at injection
molding and extrusion processors. In the rubber industry, quantitative
analysis of rubber by means of TG (Thermogravimetry) and verification
of vulcanization using DSC are becoming increasingly important.
The curing of thermosets is being investigated with DSC, aided
by reaction kinetics. DMA (Dynamic Mechanical Analysis) and TMA
(Thermomechanical Analysis) are being used more and more frequently,
especially with composite materials and in blend technology.
In literature, thermal analysis
has almost always been considered separately. In the applications
volume, "Focus on: Thermal Analysis for Polymers", released 1998
by the Fachhochschule Würzburg-Schweinfurt-Aschaffenburg,
Studiengang Kunststofftechnik and NETZSCH-Gerätebau GmbH,
practical industrial topics will be used to explain correlations
between thermoanalytical measurement techniques and conventional
test methods used in mechanics, physical chemistry and process
technology. In addition, examples will be presented dealing with
material and component development. The significance of thermal
analysis as a quick, economical test method will be emphasized.

of the book review "Focus on: Thermal Analysis for Polymers" from
Martin Dohn, Dingolfing, published in German language in the GEFTA
Notes 2/2000.

Ceramic Handbook - "TA for Ceramic
Materials"
The 2nd edition of the NETZSCH Industrial
Applications Handbook, "TA
for Ceramic Materials" is
now available. Here, in addition to an introduction to the various methods
of thermal analysis, over 30 examples are presented for raw and building
materials, silicate ceramics and glass, and, for technical ceramics,
mechanical applications as well as electronic, magnetic and optical
applications. Instruments/methods addressed are the dilatometer (DIL),
thermomechanical analyzer (TMA), glaze stress tester (GST), differential
scanning calorimeter (DSC), thermogravimetric analyzer (TG), simultaneous
thermal analyzer (STA), STA/evolved gas analysis and the laser flash
apparatus (LFA). The application examples have been updated and edited,
and some new examples - in particular, from the classic "oxide ceramics"
- have been added.
For a global view of the possible applications
of modern thermal analysis in research, development and quality assurance
of ceramics, order your copy today: e-mail: NIB-Sales@netzsch.com.
