Water Vapor Permeation Analyzers for Packaging Industry

by Systech Instruments Ltd     based in Thame, UNITED KINGDOM

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.

Oxygen Permeation Analyzers & Water Vapor Permeation Analyzers for Packaging Industry

by Systech Instruments Ltd     based in Thame, UNITED KINGDOM

Systech Illinois` comprehensive permeation range includes the recently acquired Lyssy and PermMate product lines which offer precision oxygen and water vapor analysis of packaging film barriers.

Industrial solutions for water reuse optimization

by Real Tech Inc.     based in Whitby, ONTARIO (CANADA)

Problem: With rising water costs, greater water scarcities and increasing environmental compliance regulations, reuse of water is becoming widely practiced in the manufacturing industry. For most industries, some form of treatment is required to ensure water meets standards for reuse.

Wet gas monitoring for refineries

by Kurz Instruments, Inc.     based in Monterey, CALIFORNIA (USA)

Thermal mass flow meters provide excellent measurement capabilities in dry gas flows. They have proven durability, accuracy, and repeatability. However, thermal flow meters are sensitive to liquid droplets in a wet gas stream. For a thermal flow meter to work accurately in a condensing gas environment, the probe must be placed far enough downstream so that the entrained water has condensed onto the pipe wall. In a very wet environment, any condensing liquid (commonly referred to as mist or fog) contacting the sensor probes causes a high reading due to the liquid vaporizing on the heated portion of the sensor. As a result of this deficiency, measurements with conventional thermal meters are largely ignored when moisture levels rise because there is no confidence that the measurements are true.

Gas Detection Solutions for Fertilizer Manufacturing

by Boreal Laser Inc.     based in Edmonton, ALBERTA (CANADA)

Ammonia is a notoriously difficult compound to measure accurately and reliably using standard chemical sampling techniques. The great advantage of the optical laser gas detection technique for quantitative ammonia monitoring is that the optical measurement does not affect the air being sampled – and so a true, undisturbed value for ammonia concentration can be determined. The very high resolution and specificity of the laser method also means that is no interference from other gases in the air (for example, water vapor) – such interferences complicate other optical techniques using IR or UV.

Aerosol and particle technology for pressure & temperature industries

by Palas GmbH     based in Karlsruhe, GERMANY

The reproducibility of the devices has been approved by worldwide use. In order to avoid the condensation or vaporization of the particles during the particle measurement, the isothermal and isobaric particle generation and measurement is necessary.

Gas monitoring for landfills

by Kurz Instruments, Inc.     based in Monterey, CALIFORNIA (USA)

The Kurz Insertion Mass Flow Meter products provide extremely reliable and accurate measurements with a number of features specifi cally tailored for landfi ll gas monitoring applications.

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.

Gas monitoring instruments and systems for fumigation

by Gasmet Technologies Oy     based in Helsinki, FINLAND

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 monitoring instruments and systems for process NOx measurement

by Gasmet Technologies Oy     based in Helsinki, FINLAND

Nitric acid HNO3 is an important intermediate reagent for production of several important end products, such as fertilizers, explosives, dyestuffs/pigments, pesticides, pharmaceuticals, photographic materials, plastics, and synthetic fibers. At nitric acid manufacturing plants, the Gasmet™ FTIR Gas Analyzer can be used to measure several gaseous components from the process stream for purposes of process control. A single system can be used to measure the high levels of nitrogen monoxide NO and nitrogen dioxide NO2, as well as water vapor H2O, nitrous oxide N2O, carbon monoxide CO, carbon dioxide CO2 and ammonia NH3. The fixed installation products for these purposes are the Gasmet™ CEM II measurement system, and the Gasmet™ FCX Gas Analyzers, both of which utilize the FTIR measurement technique for simultaneous multicomponent analysis of the sample gas.

Measurement solution for CFC abatement control via two stream FTIR system

by Protea Limited     based in Middlewich, UNITED KINGDOM

CFC usage in industry

Although the use of CFCs in domestic products has been widely phased out, CFCs chemicals still prove a vital ingredient in the production of insecticides and herbicides. Such products aim to increase the rate of crop production all over the world. All aspects of such a manufacturing process in relation to environmental impact must be well controlled. The use and pre-emission removal of CFCs in the intermediary steps of the insecticide production needs to be monitored with 100% efficiency.
