Medical solutions for the oxygenators

A number of components in a typical heart-lung machine require precise gas flow control. One typical component is the oxygenator, which is used for exchanging oxygen and carbon dioxide in the blood during surgical procedures. Axetris offers solutions for high-performance oxygen gas flow control in medical applications in the form of meters, controllers or gas mixing manifolds.

Oxygen Generating Systems for Waste Gas Treatment in the Semiconductor, PV and LED Industries

Waste gas treatment is an often overlooked but important function of Semiconductor, PV and LED fabrication. Several serious accidents have taken place in factories where no abatement was installed. Even today waste treatment is often seen as a cost rather than a safety issue. There are three main reasons why waste gas treatment is installed in factories: health and safety, environmental factors, and quality control.

Gas infusion technology solutions for the oxygen purifications

The two essential building blocks of life are oxygen and water. Without them there would be no life. The principle ingredients of all Oxygen Pür Skin care products are purified water and oxygen. Our oxygen infused skin serums bring life and health to the skin and the underlying dermis. Oxygen Pür is an advanced tissue oxygen serum that provides transcutaneous (through the skin) transfer of oxygen into the dermis.

Oxygen monitoring from aerobic and anaerobic for biodegradation tests

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.

Oxygen Generating Systems for Use with Ozone Generators

Twice the output of air-fed systems . . . As customers demand more ozone for less capital investment, oxygen is quickly replacing air as the industry’s preferred feed gas. Ozone output normally doubles when 93% oxygen is fed into the corona discharge.

Oxygen monitoring from aerobic and anaerobic for toxicity test

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.”

Nitrogen generation for the Marine, Oil & Gas industry

Marine conditions pose a number of challenges and issues. Size, weight, rough sea conditions, corrosion, high temperatures, cargo needing protection, just to name a few.Oxymat’s Marine, Oil & Gas division produces nitrogen PSA generator systems to the marine industry with the necessary experience and know-how to address these issues. Compared to a traditional membrane based system, PSA systems significantly decrease redundancy and can cut energy consumption with up to 30%. In addition, a PSA system can produce 5% or lower oxygen levels.With the highest quality in components, PSA systems are extremely reliable with at least 48.000 running hours before CMS replacement is needed.

Gas Sensing for Gasification

Syngas (short for synthetic gas) can be burnt and used as a fuel source, the main constituents of syngas are Carbon Monoxide (CO) and Hydrogen (H), which amount for around 85% of Syngas, and it is produced by a process called Gasification. Gasification starts with a base material which can originate from a wide variety of materials for example wood chips and pellets, plastics, municipal solid waste, sewage, waste crops, and fossil fuels such as coal. During Gasification the base material is reacted at high temperature without combustion with controlled amounts of oxygen (O) or steam. The composition of the base material combined with the amount of oxygen and heat used in the process affects the composition of the resultant SynGas, in which the CO can vary between around 20 and 60%. In addition, large amounts of H and CO are also formed. The measurement of CO is therefore an important feature in the production of SynGas.

Medical Gas Analysis for Process Industry

USP37 Medical Gas requires a specific, selective and positive identification test using a paramagnetic signal. Regular analysis of medical gas is required to ensure that the oxygen concentration is NLT 99.0% volume. Following the appropriate United States Pharmacopeia standards, in this case specifically USP37, requires an analyzer which uses a paramagnetic based technology. The Systech Illinois Paramagnetic Oxgyen Analyzer PM700 is perfectly suited for this medical gas analysis application.

Fermentation Off-Gas Analysis

In pilot plant and production scale fermentors, information relating to yield of product is of high importance. Hiden's gas analysers are configured with a multiport Off-Gas analysis manifold enabling simultaneous sampling from multiple fermentors. Data is used for the calculation of the respiratory quotient, carbon production rate and oxygen uptake rate. The Off-Gas measurement provides the respiratory quotient in a time and space averaged form and with good response time. By comparison data from multiple dissolved species probes are more specific and can provide information about stirring efficiency, aeration and feed distribution within the fermentor. Dissolved gas measurements have the advantage of giving direct information on gas uptake and for dissolved output rates. Hiden Analyticaloffers systems with either Off-Gas or dissolved species inlets or both.

Gas monitoring instruments and systems for nitric acid process

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 Catalytic Reduction unit (SCR), which deploys ammonia gas NH3 to limit emissions of NO and NO2. A modern nitric acid plant needs to monitor the emissions of these gases.

Gas analysis & monitoring system for biogas analysis

“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).
