  • New requirements for safe use and storage of liquid nitrogen and dry ice

    The College of American Pathologists ("CAP")recently imposed new requirementsto address risks related to the use and storage of liquid nitrogen ("LN2") and dry ice. Background The new requirements come after a deadly incident in 2017, when liquid nitrogen leaked at a Georgia lab that was not accredited through CAP.  Emergency responders were called to the scene when an employee ...

  • Choosing flow monitors for CEMS applications

    As a result of the 1990 Clean Air Act Amendments1, electric power plants must reduce their emissions of sulfur dioxide and nitrous oxides—the primary causes of acid rain. The U.S. Environmental Protection Agency (EPA), in its proposed rules2, designates the 111 Phase I fossil-fueled plants ^roughly 268 boiler units) that must have continuous emissions monitoring systems (CEMS) installed, ...

  • IVF Cryopreservation and Safe Handling Practices

    Couples that want to have a baby but have not been able to conceive naturally are drawn to invitro fertilization (IVF) treatments. In an IVF treatment, several eggs are fertilized at once, which creates multiple embryos. While more than one embryo may be implanted, to spur the odds of pregnancy, there are inevitably some unused embryos. The remaining embryos may be preserved cryogenically, for ...

  • Multiplexed Monitoring – To be Doubt or Not?

    There are several types of continuous emissions monitoring (CEM) systems. The technical designs may be very different, but they usually have a few things in common. The instruments providing the measurement results do not come cheap, and the systems require maintenance. However, if monitoring is to be done in more than one gas duct, then there might be a way to save costs, multiplexing. But ...

  • Pollutant reduction control and Continuous Emissions Monitoring at Waste-to-Energy Plants

    Waste is generally undesired, and best not generated at all. The second best alternative to manage waste is to recycle it. However, there is also waste that for various reasons is not recycled. Landfills have then been the old-school solution, but it is for environmental reasons becoming a less viable option. What then remains is waste incineration, in most cases while recovering the energy ...

  • Continuous Emissions Monitoring of Total Mercury

    Over the past decades, mercury (Hg, quicksilver) has gone from being a versatile commodity used in everything from thermometers to herbicides, to a partially banned substance, which name alone signals environmental issues and health concerns. Today, much use of mercury has been phased out in favour of more environmental- and health-friendly substances, and the remaining circulation of mercury is ...
