    Laboratory instruments solutions for environmental industry

    The environmental challenges require internationally accepted standards, in which limits and test methods are defined. Metrohm instruments and applications comply with a lot of international environmental standards. Substances introduced into the environment are distributed among the environmental compartments water, soil (sediment), and air, as well as among the organisms living in them (biosphere). Only if we know the type and quantity of these contaminants can we protect the environment and its inhabitants.

    Infrared temperature measurement for calibration industries

    To ensure high-precision performance from temperature measurement devices, reliable calibration is required. This can be carried out on site or under laboratory conditions, using primary or reference standard sources. Primary calibration sources are traceable to National Standards via a certified probe installed in the radiation cavity. Reference sources achieve traceability either by comparison with certified thermometers, or through purchasing a calibration certificate.

    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.
