Gas analysis & monitoring systems for gas generation
The gas generators for calibration based on the use of “Method of Permeation Tubes.”. The permeation tubes are sealed capsules containing a small amount of the component that is in contact with a permeable membrane stable. The permeation through the membrane produces a vapor of the compound of the component of small quantity, very stable as a stream in time. This permeate stream by mixing with a dilution gas controlled and precise (for example nitrogen) creates a mixture in track at the desired concentration. The flow of the permeate is measured metrically through severe weight loss of the tube thus ensuring a standard high precision.

Gas monitoring instruments and systems for fumigation
Sea cargo containers and wooden packing materials are fumigated to control the spreading of pest animals and micro-organisms. Fumigant gases are toxic and measurements are carried out as a health and safety precaution. Measurements are required by e.g. customs inspectors prior to opening containers, making the shipping companies responsible for carrying out measurements. Products shipped in containers may release VOCs from e.g. solvents and glues used in manufacturing process. The concentrations of vapors may be significant in the confined space of the container. While most containers originate in China and Southeast Asia, cargo container measurements are done in ports across the world, as the same gases are encountered in all ports.

Gas analysis & monitoring systems for leak searching
Many chemical compounds and gas are invisible to the naked eye. But there are many companies that make intensive use both during and after the production process. The manner and frequency with which companies are required to monitor, document, report and rectify any escape of volatile gaseous compounds are established by regulations extremely rigid. The technology most widely used is the “Imaging Camera” or “sniffer technology.” “When we look for gas leaks, check all systems in places that may or may not have been previously identified. These controls are carried out regularly and are very important after a shutdown.

Gas analysis & monitoring systems for semiconductor
The Cleanroom is a combined laboratory chemical, mechanical and / or electronic whose main characteristic is the presence of very pure air, that is a very low content of fine dust in suspension. In the process of semiconductor production, the airborne particles (micro-powder) go to irreparably damage the micro-photoetched that form the chip, creating an electronic circuit defective, and then discarded. This process has forced the improvement of industrial production environments, removing particles from the air, for two purposes: to increase the efficiency of production, increasing the yield of quality, and requirement of the manufacturer (of course based on the demand of the market) in shrink increasing the area of etching of semiconductors (just think of the USB storage media in a few years, went from 16 MB to 16 GB without changing the external dimensions).

Gas analysis & monitoring systems for greenhouse gases analysis
The rising levels of manmade greenhouse gases (GHGs) in the atmosphere and their resulting impact on climate is now one of the single biggest technological and environmental challenges facing the world. This makes intensified monitoring of these gases more critical than ever in order to better quantify the role of the numerous natural and manmade sources, sinks and buffers involved in the cycles of GHGs. It also enables us to objectively audit GHG fluxes at the factory, city, country and continental level. Such objective auditing is ultimately essential to facilitate effective enforcement and compliance with any regulations, laws, treaties and trading agreements based on GHG metrics such as carbon footprints.

Moisture Monitoring for Natural Gas & LNG
The presence of moisture in high-pressure natural gas from production wells causes pipelines and associated valves to freeze. High moisture content also leads to the formation of hydrates of the liquid hydrocarbons present, thus causing further difficulties. The moisture content of the gas also adversely affects the calorific value of the gas, thus lowering the quality and value of the product. Moisture is therefore measured at the point of extraction, at export stations, at gas storage locations and in the transmission grid. As natural gas often contains high levels of contaminants, more complex systems are required to maintain instrument performance over prolonged periods and to verify data collected in spot-check moisture analysis.

Gas monitoring instruments and systems for phosgene monitoring
Phosgene COCl2 is a colorless gas. While it has been used as a Chemical Weapon Agent (CWA) in the past, currently this poisonous gas is also an important reagent in synthesis in the pharmaceutical and chemical industries. The plants using phosgene are typically equipped with gas sensors to detect leaks in the indoor ambient air. The critical situations arise when equipment in contact with the gas at the manufacturing facilities are serviced and maintained. As phosgene is very poisonous, even small gas pockets in serviced equipment may be dangerous to maintenance personnel. Gasmet™ FTIR Gas Analyzers are ideal tools to monitor point sources of phosgene. The measurement technology has high specificity, may be operated continuously, and has a fast response time.

Gas monitoring instruments and systems for anesthetic gases
The anesthetic gases and vapors which leak into the indoor atmosphere during medical procedures are considered waste anesthetic gases (WAGs). The exposure is of relevance to thousands of professionals in hospitals, operating theaters, patient recovery rooms, dental offices, and veterinary clinics around the world, who may be continually exposed to the waste anesthetic gases during their workday. Typical gases of concern include nitrous oxide N2O and several halogenated compounds in vapor form, such as sevoflurane, isoflurane, enflurane, halothane, desflurane, and methoxyflurane. Short-term exposure to these gases may lead to several symptoms, such as dizziness, headaches, fatigue, nausea. Long-term exposure to some of the anesthetic agents may result in sterility, birth defects, cancer, and liver and kidney disease.

Gas monitoring instruments and systems for stack testing
Several EU directives and national laws in European countries set requirements for continuous monitoring of flue gas emissions at power plants. Further requirements are set on the quality assurance of the installed measurement systems at the plants. The relevant standard in this regard is EN 14181:2004, the quality assurance of automated measuring systems. The standard dictates how to determine that the measurement systems installed for continuous emissions monitoring at a plant operate according to the directives and regulations set. Two major parts of this on-going quality assurance cycle are the QAL2 and AST procedures. A test laboratory performs tests on the systems on-site, and determines whether the systems fulfill the set requirements or not.
