Chemical testing

Characterization of substances and reactions

Chemical and physical properties

Spectroscopic measurements, such as nuclear magnetic resonance (NMR), Fourier-transform infrared (FT–IR), near-infrared (NIR), or UV–visible (UV–vis) spectroscopy and their accurate interpretation are essential to identify your compound and to describe its molecular structure.

Substance-specific material properties, such as melting point (MP), density, solubility, or specific rotation characterize your compound. In addition, viscosity and rheological behavior can be determined, in particular for polymers. Titration is available for pH and pKa measurements.

Structure elucidation

Identifying unknown organic molecules is one of the most challenging tasks in analytical chemistry. ChemCon combines its expertise in advanced multinuclear and multidimensional NMR spectroscopy with complementary information from liquid chromatography mass spectrometry (LC–MS). The latter determines the molecular weight and fragmentation patterns of organic molecules. NMR spectroscopy is also a powerful tool to determine the structure of polymers, and with diffusion-ordered spectroscopy (DOSY) low-molecular-weight components in your polymers can be determined.

As a manufacturing company and chemical contract analysis, ChemCon brings a lot of experience to your projects.

Process control and monitoring

Between testing starting materials, intermediates, and products, ChemCon is able to support your synthesis development with in-process controls. Contact us for a quick and practicable arrangement.


Continuous process monitoring can be advantageous to better understand the thermodynamic and kinetic properties of chemical reactions and to determine safety limits for process scale-up. ChemCon offers reaction calorimetry with integrated IR spectroscopy, real-time calorimetry, as well as heat-flow, pH, and turbidity measurements.
