HPR-40 DEMS

With its modular configuration and compatibility with a range of electrochemical cells and probes the HPR-40 DEMS is an adaptable solution for laboratories working across multiple disciplines. By simplifying workflows and eliminating the need for time-consuming offline sampling techniques, it enables researchers to accelerate discovery and improve their understanding of electrochemical processes.  A range of versatile accessories are available allowing the system to be used for multiple applications utilising the same software and mass spectrometer.

The supplied ECL series of electrochemical cells feature either a vitreous carbon working electrode (ECL-Static) or sputter compatible membrane (ECL-Insight), which can be user-coated to meet the exact needs of a given experiment. This adaptability allows scientists to customise the surface for specific reactions, improving the relevance and precision of their data. The electrode’s robust design also supports repeatable, long-term experimentation.

The ECL-Probe completes the ECL series and allows for direct dissolved gas analysis in ‘off the shelf’ or custom-made cells.  The unique non-metal nature of the probe means it can be fully immersed in electrolyte without any interaction with the electrochemistry.

The HPR-40 DEMS is built to keep research moving. Its easily replaceable nanoporous membrane interface keeps performance consistent and downtime to a minimum, so you can focus on results, not maintenance. With ECL series cells placing electrocatalysts right at the membrane surface, you gain faster response times, tighter synchronisation with electrochemical measurements, and the confidence to run extended studies with ease.

The included cables enable straightforward integration of the HPR-40 DEMS with the electrochemical workstation, ensuring data synchronisation within a single intuitive software package. With QGA software, multiple-axis views make it possible to plot the interaction of potential, current, time, and mass spectrometer signals in real time.

Backed by Hiden Analytical’s 40+ years of expertise, the HPR-40 DEMS provides a complete solution for laboratories focused on energy storage, catalysis, corrosion, and advanced material studies. Its combination of flexibility, precision, and ease of use makes it an essential tool for scientists seeking accurate, actionable insights into electrochemical reactions.

ECL-Insight

• Near-instantaneous time response – direct electrode-to-MS connection delivers rapid, quantitative product detection.
• Rapid scan capability – supports extremely fast voltage sweeps (up to 100 mV/s), enabling real-time monitoring of transient processes.
• High sensitivity – detection limits as low as ~50 µA/cm² for hydrogen evolution.
• Exceptional collection efficiency – captures products directly at the electrode–electrolyte interface, providing accurate quantification even under flow.
• High-current capability – supports up to 100 mA/cm²; optimized flow design prevents bubble accumulation as gas products are instantly absorbed into the mass spectrometer even at high current densities.
• Mechanistic insight – allows observation of local CO₂ depletion, intermediate species, and concentration effects that are not accessible with conventional methods.
• Trusted accuracy – results align with conventional GC analysis, but in a fraction of the time.
• Simple to operate – supplied with a gold sputter-coated membrane as the working electrode.
• Dual-chamber design – prevents cross-contamination and cathode poisoning from anode byproducts.
• Non-metallic construction – enhances chemical compatibility and minimises interference.
• Flexible research tool – ideal for CO₂ reduction, hydrogen evolution, and isotope labelling studies.

ECL-Static

• User-friendly and versatile – optimized for straightforward setup and flexible experimentation.
• Configurable as a static or flow Cell – extra ports allow inlet and outlet flow for extended experiments.
• Customisable working surface – supplied with a vitreous carbon electrode, which can be easily coated by the user.

ECL-Probe

• Direct dissolved gas analysis – enables real-time measurements in both standard and custom electrochemical cells.
• Unique non-metallic design – fully immersible in electrolyte with no risk of interfering with the electrochemistry.
• Improved selectivity – Specialised hydrophobic support enriches gas concentration.
• Ready-to-connect with the HPR-40 DEMS.

• HPR-20 OEMS
• Sampling Inlets
• QGA 2.0
