Throughout manufacturing the analysis of gas is carried out to ensure high-quality results and minimal wastage. This includes processes such as the manufacturing of semiconductors, latex products and food, additive manufacturing, metal heat treatment and solder reflow. For example, the production of semiconductors is a thermal process that involves working with silicon. An inert atmosphere is used to prevent the oxidation of the silicon and metal films. Likewise within the solder reflow process an inert atmosphere...
Extreme heating or cooling of materials can alter the chemical or physical structure. Metal heat treatment is a process used to change properties such as the strength, density, resistance and suppleness of metals to make them more suitable for purpose. Methods vary depending on the metal used and the outcome required, however, common metallurgical techniques harnessed include annealing, brazing, tempering and hardening. When these techniques are carried out under intense heat, it is often necessary to introduce a...
Medium and high voltage electrical equipment requires insulation to prevent the arcing of electricity. SF6 gas is commonly used within Gas Insulated Switchgear (GIS) as an arc quenching and cooling medium, due to its excellent dielectric properties.
Flue-gas analyzers are designed to be rugged and accurate at the same time. They are used by the HVAC industry, energy industry, process control, glass industry, food industry, universities and analysis is required.
Dust, SO2, NOx, CO, CO2 and other gases generated in the fuel decomposition, combustion and other production processes of cement industry have a serious impact on the atmospheric environment. So it is essential to check the content of these gases for energy conservation, increase productivity, reduce energy consumption and protect the safety of life and production. The company`s gas analysis technology can accurately and reliably measure various industrial gas content, to provide a complete gas analysis solutions...
Applications within the medical and pharmaceutical industry are vast with gases being delivered directly to patients for therapy (e.g. ventilators or anaesthesia) or used for storage, cryogenic freezing or incubation. Pharmaceutical companies use gases in the manufacturing process of many products and ingredients. Additionally analysis takes place in physiology laboratories, for example, to measure oxygen depletion levels in humans with the use of a Douglas bag.
Additive Manufacturing (AM) is becoming more popular within the engineering industry as companies begin to consider it as a preferred method of component production, rather than just using AM for rapid prototyping. Any oxidisation occurring within the AM process can lead to build failures or components ultimately failing to meet the standards required due to stress test failure or density test failure.
In addition to the gas production industry, gases are used widely throughout many other sectors such as; manufacturing, electricity generation, fire suppression, research and development, and food production and storage. Throughout any process that utilises gas, it is essential to ensure that concentrations are exact and that no contaminants are present, to ensure the highest quality and expectations are met. Gas analysis can take place during many points of the processes, including the testing of gas cylinder...
Combustion is a chemical process that involves the rapid reaction of a fuel substance with oxygen and heat. During this reaction new chemical substances, such as exhaust fumes, heat and light are created. There are many types of combustion including; complete, incomplete, smouldering, rapid and turbulent. Each process can differ due to the heat source and amounts of fuel or oxygen available.
In a complex petrochemical facility there may be many thousands of potential leaks paths. Some may be leaking but most will not. Using an infrared Gas Detection camera allows the user to examine many potential leaks sources in a short time and from a distance. The EPA acknowledged gas imaging cameras, such as Opgal’s EyeCGas®, as an approved Leak Detection and Repair (LDAR) Method 21 alternate work practice (AWP).
The accurate measurement of a gas mixture composition is essential to a wide range of industries and processes. Whatever your application, the key to this success is effective gas analysis you can trust to keep your operations running.
The accurate measurement of a gas mixture is essential to metal and mineral processing. Reliable measurements are needed to manage processes ranging from effective combustion control to optimized process control.
Residual Gas Analysis is a general term for the analysis of gas and vapour species in vacuum chambers and vacuum processes.
The Hiden RGA series quadrupole mass spectrometers provide for routine, fast, wide dynamic range residual gas analysis, measuring the partial pressures of the species that are critical to vacuum quality and process requirements.

Inert gas blanketing is a process used to protect volatile, combustible or perishable products from undesirable reactions such as oxidation or explosion. Gases such as nitrogen, helium or argon are used due to their non-reactive properties. These gases are introduced to purge the oxygen within a chamber, storage container, tank or any headspace within an area containing materials that require protection.
Glove boxes are commonly transparent, sealed containers that have gloves built into the side. They allow users to create the appropriate atmosphere in which to manipulate objects or hazardous materials. Industries such as pharmaceutical, research, metal treatment and manufacturing employ gloveboxes to carry out processes such as welding or the handling of biological substances or chemicals. Gases such as nitrogen, argon or helium are used to blanket the atmosphere within the glovebox, which prevents reactions...
