    Measurement solution for fire testing for the railway industry

    A lot of research is carried out in laboratory and on real fires as to the gaseous substances produced in fire effluent. Measurement principles using analytical instrumentation are becoming more widely used in fire testing, due to the quick, real-time nature of the measurements. ISO 19702 is an international standard developed for the use of FTIR analysers in the analysis of gas from fire effluents. Further to this, local test standards such as DIN 5510, applicable to the railway industry, can provide further requirements for gases to be measured.

    Mercury monitoring for ocean cruises

    Researchers at Battelle Pacific Northwest Laboratory used a Tekran 2600 on a 2009 ship cruise. Due to the low levels of mercury in water, Tekran provided them with a custom 2600 Event Table to pre-concentrate mercury from multiple samples to push the detection limit lower. When planning an ocean bound cruise, instrument dependability is a paramount concern. At sea, there is no possibility to return instrumentation to the manufacturer for quick repair. The Tekran 2600 has a well deserved reputation for dependability and performance. If any repairs are necessary, the instrument is highly user-serviceable and easy to maintain.

    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.
