LPG is odorized to alert in case of leakage. Typical sulphur containing odorants area mercaptans such as TBM and EM, THT, organic sulphides such as DMS or mixtures. Gas Chromatography can provide the quantitative speciation of these odorants in LPG to check the effectiveness of the odorization.
Safely storing liquids and chemicals is a continuous and ongoing effort in the Petrochemical Industry. Companies operating in this industry must deal with some of the unwanted effects that oxygen creates when present inside storage containers. Through a process called nitrogen blanketing, they inject this inert gas into the vapor space and effectively lower the concentration of oxygen. This in turns decreases the risk of fire, explosion, evaporation and structural corrosion.
A safe laboratory environment requires an
effective method for clearing toxic material from fume hoods. Since all handling of toxic
materials is completed in these hoods, it is
critical to have a procedure to evaluate their
operation to assure adequate protection for
laboratory workers. The InfraRan Specific
Vapor Analyzer, factory calibrated for SF6, is an ideal instrument for measuring fume hood
efficiency in accordance with ASHRAE and
other standards. Manufacturers identify the flow
dynamics (factors that...
Biocidal chemicals like peracetic acid are very effective at killing bacterial contamination on meat, poultry and work surfaces. But, for those people who work in processing plants where large amounts of peracetic acid is used every day there is a significant risk of over-exposure.
A Safer Work Environment: Peracetic Acid (PAA), Hydrogen Peroxide (H2O2) and Ethylene Oxide (EtO, EO) are used in several industries. Worker exposure to these chemical vapors can cause serious health risks, and monitoring is the only way to ensure vapors are at safe levels. Keeping your production line moving is important to any company`s bottom line. Making sure that your production line workers are operating in a safe environment is a key component in ensuring there are no reasons to shut the line down....
Coil Coating is a high-temperature solvent vapor monitoring application in which rolls of aluminum or steel are coated with a color finish, oven cured to desired specs and sold to makers of cans, rain gutters, home appliances, building & automotive products and other fabrications. Coil coating requires the use of our PrevEx Flammability Analyzers to monitor the flammability of the solvent vapor driven off during the drying process. PrevEx analyzers accurately measure solvent mixtures and can withstand the...
For packaging film barriers, the Systech Illinois range of water vapor permeation analyzers offer a wide measurement range with precision temperature, humidity and flow control. These analyzers utilise the Coulometric P2O5 sensor, which is more sensitive and stable than infra-red and does not require calibration. The P2O5 is the primary method for absolute moisture measurement.
The installation of suitable installation material in buildings is a cost effective way to reduce energy costs. The manufacture of insulation from minerals or mineral products, such as glass. Recycling glass to form insulation materials is another way to keep the process "green".
Trace Environmental has systems installed at more than 45 storage terminals throughout the United States with our CEM and reporting software. For marine and truck racks, Trace continuously monitors the emissions for Vapor Combustor Units (VCU’s) as well as for Vapor Recovery Units (VRU’s). We are fully compliant with permit requirements for continuous stack monitoring and reporting for parameters such as VOC’s, CO, and O2. We also provide safe and reliable systems that can operate in explosion-pro...
Lyophilization, commonly referred to as freeze drying, is the process of removing water from a product by sublimation and desorption. The freeze drying process is optimised by the introduction of solvents and gas species to improve product quality and to enhance the drying process.
Hiden's gas analysers provide detailed information about the gas/vapour composition during both the primary and secondary drying phases. Detection of the on-set of the secondary drying phase is readily detected. Analysis during the...
Hiden's gas analysers provide for high sensitivity analysis of gases and vapours from gas production and storage facilities. Gas analysers provide for:
Bottled gas quality assurance
Diving gas monitoring
Solvent based inks in different colors and patterns are applied to paper, plastic, film and foil substrates. Finished products include all sorts of wrapping paper, wall covering, candy wrappers, flexible food packages, shrink labels, high quality magazines and many, many more. These industries employ ovens or dryers to remove the solvents from the finished product.
Carbon dioxide and oxygen headspace analysis for food and pharmaceutical applications. To ensure product packaging integrity and shelf life, many food and pharmaceutical products are packaged using MAP Modified Atmosphere Packaging. Systech Illinois headspace gas analyzers offers fast, accurate MAP analysis of headspace in gas flushed food and pharmaceutical products.
Blood is one of the most complex substances for determination of the Hg content. At the same time, blood is the most important diagnostic medium used for monitoring the effect of Hg vapor on the human organism. In almost all the countries, personnel of mercury-involving production facilities are regularly examined for the Hg content in blood, which should not exceed 20–50 µg/l, whereas in the case of a person unexposed to mercury vapor the blood normally contains 1–3 µg/l of Hg.
Protea has deployed FTIR gas analysers in many projects requiring the monitoring of complex mixes of VOCs. In the chemical and pharmaceutical industry, scrubbers and carbon-bed abatement plants are typical installations where the use of Protea FTIR analysers and our chemometric expertise have proved valuable to plant operators. They prove an invaluable tool in process measurements and emissions monitoring. In the laboratory, Protea can deliver instruments with all the chemometric software and support to enable...
Monitoring Hydrogen Peroxide, Peracetic Acid and Ethylene Oxide In Hospital Sterile Processing. Monitoring for chemicals (Hydrogen Peroxide, Peracetic Acid and/or Ethylene Oxide) released into the air during sterile processing is an essential part of your Quality Control (QC) program. Serving as an early warning to leaks and safety measure for your employees, ChemDAQ® monitors enable you to effectively manage the breathing environment. Just like equipment requires revalidation after a failed cycle, monitoring...
The migration of magma towards the surface in a volcano is usually accompanied by the release of gas that was previously dissolved in the magma itself. In an open conduit volcano, most of the gas escapes through the main conduits of the volcano and then through the craters. However, a significant proportion (approximately 10%) of the total quantity of gas can escape laterally through faults and fractures that are normally present in the flanks of a volcano. Therefore, increases in the amount of gas emitted...
