Solutions by field of work
Catalysis and catalytic processes
From catalyst composition to reaction monitoring. Complementary solutions for active metals, promoters, impurities, elemental distribution, process gases, isotope tracers and catalyst deactivation studies.
Research questions
What can be investigated
Selection depends on the matrix, catalytic phase, reaction conditions and required information. These techniques are complementary.
Complete characterization does not rely on one instrument. The analytical design combines bulk composition, spatial information, online gases and, where relevant, isotope measurements.

Frequently asked questions
Catalysis and analytical instrumentation
Initial guidance for platform selection. The final recommendation depends on the experimental system.
What information can be obtained in catalysis studies?
A combination of techniques can reveal elemental composition, metal distribution, gaseous reactants and products, isotope signatures and changes associated with deactivation.
Which technique monitors gases in real time?
Process gas analyzers such as the GAM line can monitor multicomponent mixtures during a reaction, according to configuration and concentration ranges.
How can active metals and promoters be evaluated?
ICP-OES or MICAP-OES can quantify elements after suitable preparation; microanalysis and laser ablation add spatial information.
Can isotopes be used to study mechanisms?
Isotope tracers and ratios can support investigation of reaction pathways, exchange and sources when the experimental design is suitable.
How can catalyst deactivation be investigated?
Before-and-after comparisons can combine composition, elemental distribution, CHNS/O, gases and isotopes to assess coke, component loss and other changes.
