The HPR-40 DEMS is a versatile option for labs working in a variety of fields because of its modular design and compatibility with a variety of electrochemical cells and probes.

Researchers can speed up discovery and deepen their understanding of electrochemical processes by streamlining workflows and removing laborious offline sample methods. The system can be utilized for several applications with the same mass spectrometer and software, thanks to a variety of adaptable accessories.

The vitreous carbon working electrode (ECL-Static) and the sputter-compatible membrane (ECL-Insight) of the provided ECL series of electrochemical cells can be user-coated to precisely match the requirements of a given experiment.

Thanks to this flexibility, scientists can customize the surface for particular reactions, which enhances the accuracy and relevance of their findings. The sturdy design of the electrode also facilitates long-term, consistent testing.

The ECL-Probe completes the ECL series by allowing for direct dissolved gas analysis in either “off the shelf” or custom-made cells. The probe’s non-metal composition allows it to be fully immersed in electrolyte without interacting with the electrochemistry.

The HPR-40 DEMS's purpose is to maintain research momentum. Its readily changeable nanoporous membrane interface minimizes downtime and maintains consistent performance, allowing users to concentrate on results rather than upkeep.

ECL series cells, which position electrocatalysts directly at the membrane surface, allow for faster response times, closer synchronization with electrochemical measurements, and lengthy research.

The provided cables allow the HPR-40 DEMS and the electrochemical workstation to be easily integrated, guaranteeing data synchronization inside a single user-friendly software package. The QGA software's multiple-axis displays make plotting the interaction of potential, current, time, and mass spectrometer signals in real time feasible.

The HPR-40 DEMS, supported by Hiden Analytical’s more than 40 years of experience, offers a comprehensive solution for labs specializing in advanced material research, corrosion, energy storage, and catalysis. Due to its versatility, accuracy, and user-friendliness, it is a vital tool for researchers looking for precise, insightful data about electrochemical reactions.

ECL-Insight

• Near-instantaneous time response: A direct electrode-to-MS connection provides quick, quantitative product detection.
• Rapid scan capability: Allows incredibly quick voltage sweeps (up to 100 mV/s), making observing transient events in real time possible.
• High sensitivity: Detection limits for hydrogen evolution as low as about 50 µA/cm².
• Exceptional collection efficiency: Provides precise quantification even under flow by directly capturing products at the electrode–electrolyte interface.
• High-current capability: Supports up to 100 mA/cm²; even at high current densities, gas products are immediately absorbed into the mass spectrometer due to an efficient flow design that avoids bubble formation.
• Mechanistic insight: Makes it possible to observe effects of concentration, intermediate species, and local CO₂ depletion that are not possible with traditional techniques.
• Trusted accuracy: The results are consistent with standard GC analysis, but in a fraction of the time.
• Simple to operate: Provided with a working electrode made of a membrane coated with gold sputter.
• Dual-chamber design: Stops cathode toxicity from anode byproducts and cross-contamination.
• Non-metallic construction: Increases the compatibility of chemicals and reduces interference.
• Flexible research tool: Perfect for studies on isotope labeling, hydrogen evolution, and CO₂ reduction.

ECL-Static

• User-friendly and versatile: Suited for flexible experimentation and easy setup.
