    Gas monitoring instruments and systems for flavoring agents

    Manufacturing of powdered and liquid flavorings and fragrances involves production phases where flavoring chemicals may be released into the ambient air breathed by workers. Exposure control by gas analyzers in the production rooms and laboratories is necessary to ensure that the Time-Weighted Average (TWA) concentrations do not exceed the maximum Permissible Emission Limit (PEL) values.

    Gas monitoring instruments and systems for compressed breathing air

    Compressed breathing air is subject to strict limits of harmful contaminants defined in European standard EN 12021 and various defence standards such as DEF STAN 68-284 issue 3. The testing interval of breathing air compressors and associated equipment is 3 months and gases tested include carbon monoxide, carbon dioxide and oil vapour defined as hexane and heavier hydrocarbons. EN 12021 covers underwater applications including self-contained open circuit compressed gas breathing (SCUBA) and compressed gas line...

    Environmental solutions for the flue gas temperature control

    Evaporative gas cooling and conditioning systems help protect your downstream equipment, enhance air pollution control performance, reduce gas volumes, and increase production capacity. Central to our systems are Turbotak atomizing nozzles, which introduce a controlled amount of finely atomized water into the hot gas stream to reduce and/or maintain gas temperature. The water evaporates, while absorbing heat from the gases, for free-flowing dust, zero liquid discharge, and minimal or no wall buildup.

  • Measurement solution for medical workplace monitoring

    In taking a responsible stance on the exposure of workers to any potential hazardous gases, there is a need for workplaces using anaesthetic gases, such as hospital operating rooms or research laboratories, to control the level of waste anaesthetic gas in the ambient air. Anaesthesia machines, ventilators, breathing systems and waste gas scavenging systems will all contribute to te background level of he anaesthetic gases that are present in the environment within a facility, whether those machines are in a good...

  • Gas detection solutions for the breathing air gas sensors industry

    If you use compressed breathing air it is essential to monitor for contaminants including carbon monoxide (CO), carbon dioxide (CO2) and volatile organic compounds (VOCs) as well as oil mist and water vapour. Some people spot-check their compressed air quarterly using colorimetric tubes, but it is safer to test the air continuously. If you are operating or servicing equipment containing fluorinated greenhouse gas (F gas) in refrigeration, air conditioning and fire protection systems you need to adhere to requireme...

    Odor control for composite

    A Single Solution To Manage Composite Odors: Many resins used in the composite industry emit styrene vapors which are considered hazardous in high concentrations and whose odor is an unpleasant nuisance. This gas is categorized as a volatile organic compound (VOC) and listed by the United States Environmental Protection Agency (US EPA) as a Hazardous Air Pollutant (HAP). Styrene is considered highly reactive in the atmosphere and may contribute to smog formation and the production of secondary air pollutants.

    Capabilities of the Adsorbent Tube Injector System (ATIS™)

    The Adsorbent Tube Injector System (ATIS) was developed at Supelco® by R&D Scientists, as a tool to assist in our comprehensive adsorbent research for thermal desorption tubes. The ATIS provides an efficient means of transferring calibration standards in either the gas or liquid phase onto the adsorbent packed tubes. The ATIS employs the technique of flash vaporization to vaporize the sample in a continuous flow of inert gas; the inert gas carries the sample to the tube. The sample pathway of the ATIS is construct...

    Formaldehyde and Acetaldehyde Determination in Air Using Fully Automated On-Line Desorption and Analysis of DNPH Cartridges

    Airborne aldehydes and ketones are collected by passing air through a cartridge containing 2,4-dinitrophenylhydrazine (DNPH). Carbonyl compounds react with the DNPH to form hydrazones, which are immobilized on the cartridge. These compounds can be easily eluted from the cartridge with acetonitrile and analyzed by HPLC with UV detection. Traditionally, this analysis including the workup contains a series of manual steps, which can become time-consuming and could incur experimental error. Automating the extraction...

    Environmental solutions for the iron and steel industry

    Evaporative Gas Cooling and Conditioning: The evaporative gas cooling and conditioning system uses a finely atomized water spray to cool EAF, BOF off-gases from over 2,400°F (1,315°C) to as low as 240°F (115°C), protecting ductwork and downstream air pollution control equipment from high temperature and sparks, while providing rapid cooling for dioxin and furan control. By optimizing humidity levels, it helps electrostatic precipitators because the water spray completely evaporates while cooling...

    Odor control for refining/petroleum

    You refine the fuel, we’ll remove the odors. Oil refineries and petrochemical plants may generate large volumes of odor from the processing and refining of different fuels. Sulfides, mercaptans, and hydrocarbon compounds are all closely related to the oil industry. The odors generated from these industrial compounds are of a high nuisance value and generally create concern among local air boards and the public. Ecosorb odor removal products may be used in a variety of areas around the refinery including...

    Analysis of Isocyanates Using the ASSET™ EZ4-NCO Dry Sampler

    Isocyanates are used as a raw material to produce a number of products . Personal exposure can occur while the products made with isocyanates are being applied, or when the materials are removed by grinding or thermal degradation. Workers who are exposed to these compounds are at risk for respiratory disorders and asthma. The highly reactive nature of the isocyanate compounds and the low occupational exposure limits put high demands on both sampling and analytical techniques for monitoring of isocyanates in...
