Environics® Ambient Monitor Calibrator with Ozone Generators facilitate dynamic calibration of ambient air analyzers. These instruments automatically perform zero, precision, span and multi-point calibrations using NO, NO2, SO2, CO, O3, hydrocarbons and other gases of interest. All ozone generators are factory calibrated using a NIST traceable ozone standard. The Series 6100, Series 6103 and Series 9100 all meet or exceed U.S. Environmental Protection Agency requirements.

Continuous Emissions Monitoring Calibration Systems (CEMCS)

by Environics, Inc.     based in Tolland, CONNECTICUT (USA)

The Environics Series Continuous Emissions Monitoring Calibration Systems (CEMCS) have been used in CEM vans and laboratories for over twenty years. They meet or exceed the performance requirements of the United States EPA 40 CFR Part 51 Method 205 Appendix M. Our systems are custom built, computerized, mass flow controller based gas calibration systems which allow you to dilute a single high concentration cylinder of span gas to low levels for the calibration of gas analyzers.

Measurement of oil in wax for oil & gas industry

by Oxford Instruments plc     based in Abingdon, UNITED KINGDOM

The measurement of oil in wax is important within the oil refining industry because wax derived from petroleum sources is an important by-product of the oil refining process. These waxes are widely used in the manufacture of many materials and products as they have the ability to confer specific mechanical and physical properties such as flexibility, hardness and friction. A wide variety of waxes is manufactured with specific characteristics. One of the most critical factors controlling wax properties is the oil content. This means routine measurement of the content of oil in wax is essential for consistent control of the production process. Our benchtop NMR analyser MQC systems provides a fast, simple and accurate method of measuring oil in wax. The MQC may be calibrated to provide results equivalent to ASTM D721-06 and IP 158.

Gas Detection

by Argus-Hazco     based in Chesterfield, MICHIGAN (USA)

Gas Detection is our core business, whether portable, colormetric, fixed systems or Hazmat. We do more than get you the equipment you need--we also help you select it, calibrate it, service it and maintain it. Our technicians, our sales reps and top management can speak with authority on the capabilities of our equipment and match it to your specific application. And we are the champions of the one-of-a-kind solution, because we have the know-how and the right tools.

Computerized instrumentation for the medical gas flow and scientific research

by Environics, Inc.     based in Tolland, CONNECTICUT (USA)

Environics gas mixing, blending and dilution systems provide for precise mixing of gases for a wide variety of clinical applications. Our systems can produce gas concentrations from percent to ppb levels for single or multi-point calibration. The high accuracy of our mixers make them the units of choice for a wide variety of laboratory and research applications. For example, Environics Biological Atmosphere Incubation Mixers provide stable and accurate gas mixes for any laboratory or clinical need. You can generate the specific reduced oxygen environments needed for anerobes as well as the enriched oxygen environments needed in a variety of cellular, viral and high density culture applications. Systems can also be used to create a specific and stable gaseous environment in a clean room. In all cases, the Environics Atmosphere Mixers allow you to use less expensive single-gas cylinders or bulk tanks in place of a high number of expensive blended cylinders.

Testing Fume Hood Flow Dynamics using SF6 as a Tracer Gas

by Spectro Scientific     based in Chelmsford, MASSACHUSETTS (USA)

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 affect air flow in the hood and performance with air) using the ratings AM (as manufactured), AI (as installed), and AU (as used). A fume hood evaluation conducted under its operational environment is critical, as these tests will indicate any installation shortcomings as well as direct workers in proper laboratory hood techniques.

Capabilities of the Adsorbent Tube Injector System (ATIS™)

by Sigma-Aldrich Co., LLC     based in Bellefonte, PENNSYLVANIA (USA)

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 constructed of glass and stainless steel. The calibration standard is injected by a syringe through a replaceable septum in the center of the injection glassware, which is heated. After enough time has elapsed, typically less than five minutes, the tube is removed from the ATIS and analyzed using the appropriate analytical technique for that adsorbent tube.

O2 Monitoring in Air

by Unisearch Associates Inc.     based in Concord, ONTARIO (CANADA)

Oxygen (O2) is a colorless odorless gas, essential to all life on Earth but damaging in high concentrations. An O2 analyzer should thus be employed for safety management and air pollution prevention purposes. LasIR MP110 is perfect for continuous emission monitoring of O2. It is based on TDLAS technology and can be calibrated as an O2 analyzer, providing accurate and reliable measurements. It quickly responds to changes in compound concentration, thus providing continuous emission monitoring for the specified gas.

HCl Monitoring in Air

by Unisearch Associates Inc.     based in Concord, ONTARIO (CANADA)

Hydrogen chloride (HCl) is a colorless, sometimes slightly yellow, gas. It is an undesired environmental component that may be damaging to workers and the surroundings. Exposure limits have thus been established by industries to make sure that the workers operate in a safe environment. HCl monitoring is especially required for incinerators, coal-fired power plants, aluminum recycling and cement plants. Unisearch offers a reliable and easy-to-use HCl analyzer – the TDLAS-based LasIR system. Studies have shown that TDLAS equipment provides data that is more accurate than conventional gas monitoring equipment. When calibrated for HCl monitoring, TDLAS is able to detect this gas among other gases present in the area and provide continuous updates with regards to the changes in its concentration.
