OPSIS provides various monitoring solutions for marine vessels. One application is to monitor in Inert Gas Generators (IGG) onboard ships to control the quality of the nitrogen. The reliable systems supply accurate values continuously, and presents it directly to the control system.
Biodegradation tests involve testing samples in response to various parameters: dilution, nutrient addition, pH, temperature, and others. The pattern of oxygen uptake in aerobic tests; nitrogen gas production in anoxic denitrification tests; methane production in methanogenic tests; hydrogen production during glycolysis; and carbon dioxide production during fermentation reactions gives a measure of the rate and extent of biodegradation of the organic constituents of the test sample.
AppliTek’s gas analyzer system allows to monitor and control precisely oxygen levels in the hydrogen feed of the HCl burner. The analyzer system can be equipped with either an electrochemical cell, by alternating Pressure Paramagnetic or with a Tunable Diode Laser (TDL).
Toxicity of pure chemicals is assessed using respirometers by adding increasing concentrations to an active culture. The concentration at which oxygen uptake or gas production begins to decrease is known as the “threshold toxicant concentration.”

Our range of gas monitoring instruments are used to measure the constituents of Biogas and monitor Landfill sites for Methane (CH4), Carbon dioxide (CO2), Hydrogen sulphide (H2S), Carbon Monoxide(CO) and Oxygen (O2).
In most combustion process atmospheric nitrogen reacts with oxygen in high temperature conditions to produce nitrogen oxides (NOx). Total NOx production is the sum of nitrogen monoxide NO and nitrogen dioxide NO2. The emissions of these gases are controlled through setting of emission limit values (ELVs) for power plants.
Modern production method of nitric acid production may lead to generation of several different gaseous emission components, such as nitrogen oxides (NOx), ammonia NH3 and nitrous oxide N2O. Nitrogen monoxide is an intermediate gaseous product in manufacturing of nitric acid HNO3. NO is formed in a catalytic reaction between ammonia and molecular oxygen O2. But undesirable side reactions may result in formation of nitrogen dioxide NO2 and nitrous oxide N2O. The NO and NO2 emissions can be reduced by use of Selective...
“Biogas” means a mixture of various types of gas (mostly methane) produced by bacterial fermentation in anaerobic conditions(absence of oxygen) of organic residues from waste, decaying plant, carcasses in putrescence. The analyzers of biogas by Infrared cells carry out the continuous analysis of CH4, O2, CO2, H2S and NH3. The whole process sees the decomposition of organic material by some types of bacteria, producing carbon dioxide, molecular hydrogen and methane(methane conversion of organic compounds...
We are proud to be the world leader in gas analysis provision to the amazing world of commercial diving. We created our first commercial diving monitor in the early 1980s, the Analox 100. We started to work with customers including Divex (now known as JFD), Advanced Marine and Amron... and the rest is history. Our life-supporting oxygen, carbon dioxide, carbon monoxide and hydrocarbon analysers can be found on almost every diving system in the world. Our vast range of products includes the SDA range which...
Fixed & Portable Gas Detectors for Laboratories: A wide variety of gases are used in labs such as carbon dioxide, argon, helium, nitrogen and oxygen. These gases pose a serious risk should they leak, this risk can occur from fixed piped gas systems or individual cylinders of gases. Analox offer a range of fixed & portable gas detectors suitable for various laboratory processes which use gas and are ideal for detecting gas leaks. From portable oxygen monitors, such as our Aspida, to fixed monitors such as...
Hydrogen sulfide is the chemical compound with the formula H2S. H2S is colorless, toxic and flammable and is responsible for the foul odour of rotten eggs and flatulence. Hydrogen sulfide often results from sulfur reducing bacteria in nonorganic matter (in the absence of oxygen), such as in swamps and sewers (anaerobic digestion). H2S also occurs in volcanic gases, natural gas and some well waters.
Carbon monoxide poisoning is the most common type of fatal poisoning in many industrialized countries. Carbon monoxide is a colourless, odorless and tasteless gas caused by the incomplete combustion of hydrocarbon fuels. Carbon monoxide is a toxic gas to the human body, when inhaled it binds to hemoglobin, myoglobin, and mitochondrial cytochrome oxidase reducing oxygen storage, transport and respiration in these organelles.
Production of aluminum from its ores at aluminum smelters results in carbon dioxide CO2, carbon monoxide CO, sulfur dioxide SO2, and hydrogen fluoride HF gas emissions during the electrolytic process phase to the atmosphere. The gas emissions need to be monitored. Typically the smelters have emission limit values (ELVs) for sulfur dioxide and hydrogen fluoride emissions. These emissions should be measured accurately and with good precision, to ensure the smelter does not exceed its emission limit values. In...
Several gases are used in the hospitality industry, mainly carbon dioxide (CO2) and nitrogen (N2). These gases pose a serious risk should they leak, this risk can occur from fixed piped gas systems or individual cylinders of gases. Analox offer a range of fixed & portable gas detectors suitable for various applications which use gas, including beverage dispensers, and are ideal for detecting gas leaks. From portable oxygen monitors, such as our Aspida, to fixed monitors including our Ax60+ and O2NE+, our full...
