6 Reasons Why Pharmaceutical Laboratories Trust NETZSCH Thermal Analysis
From thermal analysis to e-learning: Discover how NETZSCH supports pharmaceutical laboratories with DSC, TGA, STA and decades of application expertise.
Especially in drug development and stability assessment, pharmaceutical laboratories face one common challenge: making reliable decisions based on limited sample material while meeting the highest quality standards.
For decades, Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA) have been indispensable tools in pharmaceutical research and testing. Today, modern instrumentation, intelligent software, and integrated workflows make these techniques even more powerful, efficient, and accessible.
Here are six reasons why NETZSCH DSC and TGA systems continue to support pharmaceutical laboratories worldwide.
Reason 1: One Technology – Countless Applications
Pharmaceuticals are complex. Active pharmaceutical ingredients (APIs), excipients, formulations, packaging materials, and drug-device combinations all require different analytical approaches.
DSC helps characterize:
- melting behavior
- glass transition temperatures
- specific heat capacity
- polymorphism
- compatibility of mixtures
- process-induced transformations
- eutectic purity
TGA complements these insights by providing information on:
- moisture and solvent content
- composition
- thermal stability
- decomposition pathways
- pyrolysis behavior
Furthermore, kinetics evaluation can be performed based on thermal analysis data. With the help of the NETZSCH Kinetics Neo software package, initial information about the shelf life of a drug can be derived from its thermal stability – even under different climatic conditions.
Using a combination of TGA and a gas analysis system, such as FT-IR or GC-MS, it is also possible to identify gaseous species evolved during heating and gain deeper insight into decomposition mechanisms and mass loss processes.

Simultaneous Thermal Analysis: Two Techniques in One Instrument
Simultaneous thermal analysis combines the best of both worlds by measuring heat-flow (DSC) and mass-change (TGA) data of the same sample under completely identical experimental conditions, thereby simplifying data interpretation and increasing efficiency.
The new STA 319 Jupiter® is ideal for laboratories seeking to maximize information gained from a single experiment.
Whether investigating formulation changes, studying stability, or supporting regulatory submissions, NETZSCH offers solutions covering the entire pharmaceutical workflow.
Reason 2: Minimal Sample Preparation
Thermal analysis simplifies laboratory work.
Most pharmaceutical samples can be measured directly without digestion, extraction, or extensive preparation. Powders are simply placed in crucibles or pans; liquids and semi-solid substances can also often be analyzed directly as received.
For DSC measurements, compacting powder samples can further improve thermal contact with the pan bottom and enhance measurement quality.
This straightforward workflow saves time, reduces operator influence, and minimizes the risk of introducing artifacts.

Reason 3: Meaningful Results from Just a Few Milligrams
During the early stages of development, sample availability is often limited.
Only a few milligrams are typically sufficient for DSC, TGA, or STA experiments. This makes thermal analysis particularly valuable for:
- pre-formulation studies
- API development
- compatibility screening
- formulation optimization
- Investigations involving expensive or limited materials
Small sample requirements enable rapid decision-making while conserving precious substances.
Whether the sample is solid, semi-solid, or liquid, thermal analysis allows meaningful investigations with minimal material consumption.
Reason 4: Fast Insights Supported by Smart Software
Reliable decisions depend on accurate results and their interpretation.
Modern NETZSCH software tools accelerate the process from experiments to gaining insight.
Features such as:
- AutoEvaluation
- Identify database search
- automated workflows
help users quickly generate and interpret results and compare measurements against extensive databases.
With these efficient software tools for NETZSCH instruments such as the DSC 300 Caliris®, TG 309 Libra®, and STA 319 Jupiter®, laboratories can increase their throughput without compromising on data quality.
Using a simultaneous thermal analyzer enhances efficiency even further, as two complementary signals can be recorded in a single experiment. This reduces experimental effort while providing a more comprehensive understanding of the sample's behavior.

Reason 6: Established Methods You Can Trust
Differential Scanning Calorimetry and Thermogravimetric Analysis are not emerging technologies – they are established analytical methods recognized both in universities and throughout the pharmaceutical industry.
Simultaneous thermal analyzers, such as the new STA 319 Jupiter®, integrate both techniques into a single instrument, facilitating data interpretation while increasing laboratory efficiency.
Both techniques are referenced in major pharmacopeias, including US Pharmacopeia (USP, chapter <891>), European Pharmacopoeia (Ph. Eur. 2.2.34) and Japanese Pharmacopoeia (JP), which are of fundamental importance in the following areas:
- research and development
- quality control
- contract testing
- stability assessment
- regulatory support
NETZSCH analysis instruments are specifically designed to meet these requirements and support laboratories in generating reliable, reproducible results every day.
