Thermal Analysis for Testing Labs Guide
METTLER TOLEDO's "Thermal Analysis for Testing Labs" guide was designed to support users of thermoanalytical instrumentation in testing laboratories.
Thermal Analysis for Testing Labs
Testing laboratories worldwide play an essential role in the assessment of materials, providing independent and unbiased test results for manufacturers and consumers alike. Typical tasks commissioned to testing labs include incoming material inspection, final goods release, product failure analysis and comparison of competitor materials.
Thermal analysis equipment can be found in most analytical, research and QC laboratories. The method was historically employed for the investigation of polymers in either testing or research laboratories. Nowadays, however, thermal analysis encompasses a broad range of specialized characterization techniques used to investigate a plethora of samples, including chemicals and petrochemicals; active compounds and excipients of pharmaceuticals; metals and alloys; and food.

Meeting regulatory requirements while maintaining a competitive edge is a daily challenge in any analytical testing laboratory. Consequently, analysts are under increasing pressure to perform correct measurements, identify measuring errors quickly, and be aware of possible measurement uncertainties – all while reducing project turnaround times. These tasks translate into the following routine procedures: method validation, SOPs, instrument assessment and calibration, selection of reference materials, and data handling, storage and approval.
Thermal stability and aging, kinetics, melting behavior, crystallization mechanisms, curing and compositional analysis are all examples of properties measured by thermal analysis. Despite being relatively easy to perform with the right instrumentation, the output in terms of measured properties, and the possibilities for interpretation, are exhaustive. Typical tasks commissioned to testing labs include inspection of incoming materials, final goods release, product failure analysis and comparison of competitor materials.
The abovementioned topics are addressed in dedicated chapters of the "Thermal Analysis for Testing Labs" guide, which describes the various techniques and their applications, along with useful application examples. The guide also highlights technological advances that contribute to safe and efficient thermal analysis workflows. These include easy operating procedures, safe user guidance, excellent data handling and storage, and the possibility of automation in hardware and software.
