    Water Vapor Permeation Analyzers for Packaging Industry

    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.

    Testing Fume Hood Flow Dynamics using SF6 as a Tracer Gas

    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™)

    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.

    Low concentrations monitoring of benzene and aromatic hydrocarbons (BTEX) for pollution control and environmental monitoring

    With over 15 years of experience in the measurement of volatile organic compounds (VOC), Environment SA announces the VOC72M, a new generation analyzer for the measurement of BTEX compounds by gas chromatography with photo-ionization detector (PID). The VOC72M can handle up to 40 compounds and eight configurations for analysis. This compact and fully automated analyzer with wide voltage range specifications (90-240V) provides equivalent performance to the laboratory chromatographs and is particularly suited to fixe or mobile ambient air quality monitoring laboratories. The VOC72M is fitted with a PID detector new generation, much more sensitive, more stable and whose lamp does not need to be cleaned; the analyzer integrates flow control fittings a 3 levels security system built on and uses only one gas (nitrogen). This robust and low maintenance instrument performs all the functions (sampling, analysis and data management) in a simple and completely autonomous mode. It is a particular

  • Continuous Emissions Monitoring Calibration Systems (CEMCS)

    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.
