In addition to flexible modules, the innovative SIPROCESS GA700 series also includes a new housing type: the Ex d field device with pressure-resistant enclosure. It contains a field operating device consisting of an Ex d casing with attached Ex e connection housing plus a connected Ex d field module.
The new SIPROCESS GA700 series of gas analyzers makes it possible to combine up to two modules in one housing: in either a wall-mounted housing or in a 19" rack housing with three different height units, depending on individual requirements.

Gas Analyzers
Gas analyzers are used for precise determination of gaseous components in technical systems, process plants or environmental applications. They enable quantitative and qualitative analysis of gas mixtures, monitoring of process gases, emissions or purity requirements. Typical components include gas sampling systems, sensor or detector units, analysis modules and evaluation and interface units.
FAQ
Which methods are used in gas analyzers?
Commonly used methods include electrochemical sensors, infrared (IR) and near-infrared (NIR) spectroscopy, Raman spectroscopy, mass spectrometry, gas chromatography and optical measurement techniques such as laser absorption. The choice depends on gas species, concentration range and application requirement.
Which gases and parameters can be analyzed?
Gas analyzers cover a broad spectrum: from oxygen (O₂), carbon monoxide (CO), carbon dioxide (CO₂), hydrogen sulfide (H₂S), ammonia (NH₃) to complex gas mixtures, VOC components, noble gases or trace constituents. Parameters such as humidity, temperature and pressure can also be measured.
Where are gas analyzers typically used?
Typical fields of application include process industry (petrochemical, chemical), energy and power plant sector, water and wastewater technology, biogas plants, environmental monitoring, cleanroom technology as well as research and development.
What are the key specifications when selecting analyzers?
Important specifications include measuring range, detection limit, selectivity against interfering gases, repeatability, accuracy, response time, sampling method (direct gas, grab sample, analyzer), temperature and pressure conditions as well as maintenance requirement.
What is the role of sampling and sample preparation?
Sampling is often the most critical part: condensation, particle load, pressure and temperature changes or chemical reactions in the sample line can impair measurement quality. Suitable filters, dryers and materials are therefore essential for valid results.
How is calibration and quality control performed?
Calibration usually uses certified reference gases or gas mixtures and must be documented regularly. Additionally, functional testing or validation runs are often carried out to verify the measurement chain, sampling system and software functions.
Which interfaces and evaluation options do analyzers offer?
Analyzers have digital and analog interfaces (e.g. 4–20 mA, Modbus, Ethernet) for integration into control systems or supervisory systems. Data logging, trend analysis, alarm detection and reporting are key functions for traceability and optimization.
What challenges exist in gas analysis?
Typical challenges include low concentrations, complex gas mixtures, sensor drift, calibration effort, sampling and preparation issues as well as changing environmental conditions. A systematic approach and regular maintenance are therefore essential.
What advantages do modern gas analyzers offer?
Modern analyzers offer high accuracy, fast response times, modular design, simple integration, automated sampling and remote monitoring. They enable precise analysis with reduced operating costs and high process or environmental safety.
