The Critical Role of Hydrogen Analysis in Industry

Why Hydrogen Purity Matters

Hydrogen is widely used across multiple industries, and its purity directly affects the performance, safety, and efficiency of various processes. Even minor impurities can lead to inefficiencies, increased operational costs, and compromised safety.

Key Applications Requiring Accurate Hydrogen Measurement

1. Fuel Cells and Renewable Energy
   • Hydrogen fuel cells rely on ultra-pure hydrogen to function efficiently. Impurities such as oxygen, nitrogen, and carbon dioxide can degrade fuel cell performance and lifespan.
2. Semiconductor Manufacturing
   • Hydrogen is used in semiconductor fabrication for processes such as silicon wafer production and annealing. Any contamination can affect the integrity of semiconductor components.
3. Industrial Heat Treatment
   • Many metal processing and heat treatment applications use hydrogen as a reducing gas. Precise measurement is essential to maintain process consistency and product quality.
4. Aerospace and Automotive Applications
   • Hydrogen-powered vehicles and aerospace applications require meticulous monitoring of gas composition to ensure performance and safety.

Regulatory and Safety Standards in Hydrogen Handling

Governments and regulatory bodies worldwide have implemented strict standards for hydrogen purity in various industries. Adhering to these standards is crucial for ensuring safe operations, reducing environmental impact, and maintaining product efficiency.

The Challenges of Hydrogen Gas Analysis

Hydrogen is a crucial gas in multiple industrial applications, including renewable energy, fuel cells, aerospace, and pharmaceuticals. However, its lightweight nature, high diffusivity, and small molecular size make accurate measurement particularly difficult. Ensuring precise hydrogen analysis requires cutting-edge sensor technology, robust gas-handling methodologies, and an understanding of environmental factors that can affect readings.

This section explores the key challenges of hydrogen gas analysis and how Cambridge Sensotec’s R3100 and R1100 Hydrogen Analysers overcome these obstacles.

Hydrogen’s Unique Properties and Their Measurement Challenges

Hydrogen is the lightest element in the periodic table, making it highly volatile and prone to rapid dispersion in the air. Additionally, it exhibits low viscosity and high diffusivity, meaning it can easily escape through the tiniest of leaks, even in well-sealed systems.

Beyond its physical properties, hydrogen also interacts with other gases, which can complicate measurement if sensors are not designed to compensate for cross-sensitivity. Furthermore, environmental factors such as temperature fluctuations and pressure variations can lead to inconsistent readings if not properly accounted for in the measurement process.

Common Challenges in Hydrogen Detection and Analysis

1. Leakage Risk & Gas Containment Challenges

• Hydrogen’s tiny molecular structure makes it highly permeable, meaning it can pass through materials that would typically contain heavier gases like oxygen or nitrogen.
• Leaks can pose serious safety hazards, particularly in enclosed spaces where hydrogen can accumulate and create an explosion risk.
• High-purity hydrogen applications, such as fuel cell technology, require leak-tight containment to prevent contamination and ensure consistent performance.

Solution with Cambridge Sensotec’s R3100 and R1100:

• The R3100 and R1100 analysers are equipped with advanced detection technology that can identify even the smallest traces of hydrogen leakage.
• Their high-sensitivity sensors provide real-time monitoring, ensuring leaks are detected before they become hazardous.
• Continuous gas sampling helps in early leak detection, preventing potential safety incidents.

2. Cross-Sensitivity with Other Gases

• Many conventional gas analysers struggle to differentiate between hydrogen and other gases such as oxygen, nitrogen, and carbon dioxide.
• Impurities in hydrogen streams—such as moisture, hydrocarbons, and inert gases—can skew measurement accuracy, leading to incorrect purity readings.
• In mixed-gas environments, traditional sensors may misinterpret gas compositions, affecting process control in industries such as semiconductor manufacturing and heat treatment.

Solution with Cambridge Sensotec’s R3100 and R1100:

• The R3100 Hydrogen Analyser uses Thermal Conductivity Detection (TCD) technology, allowing precise differentiation between hydrogen and other gases.
• The R1100 Hydrogen Analyser utilises Electrochemical (EC) sensors, which are specifically designed to measure hydrogen concentrations accurately while filtering out interferences from surrounding gases.
• Advanced background gas correction technology ensures highly accurate readings even in mixed gas environments.

3. Sensitivity to Environmental Conditions

• Temperature and pressure variations can significantly alter gas behaviour, leading to inaccurate readings.
• Fluctuating humidity levels can introduce condensation, affecting sensor performance.
• High-precision applications, such as hydrogen fuel production and aerospace applications, require analysers that can compensate for environmental factors to ensure consistent results.

Solution with Cambridge Sensotec’s R3100 and R1100:

• Both analysers feature built-in temperature compensation, ensuring stable readings even under fluctuating environmental conditions.
• R3100’s high-precision thermal conductivity sensor adapts to varying temperatures and pressures, minimising drift and improving accuracy.
• The R1100’s electrochemical technology is engineered to perform reliably in harsh industrial environments, preventing deviations caused by humidity or temperature shifts.

4. Ensuring Hydrogen Purity for Industrial Applications

• Many industries require high-purity hydrogen (99.99% and above) for critical processes. Even small contaminants can impact fuel efficiency, semiconductor manufacturing, or chemical processing.
• Traditional methods of hydrogen analysis can be time-consuming and require manual adjustments, leading to inefficiencies in industrial production lines.

Solution with Cambridge Sensotec’s R3100 and R1100:

• The R3100 Hydrogen Analyser provides high-accuracy measurements in real-time, ensuring purity levels remain within industry specifications.
• The R1100’s fast response time allows for immediate detection of impurities, ensuring continuous quality control in production environments.
