  1. pH Standards: A pHresh Take

     

    The theory of pH buffers was first outlined to meet the growing requirements in biomedical research for pH control. Growing mammalian cells in culture media is highly pH-sensitive; the addition of a pH buffer stabilizes pH and ensures successful cell growth.

    Some pH buffers are almost transparent, having been produced to use in ultraviolet and invisible spectroscopy. They are highly suitable for spectrophotometric determinations due to their low pH range.

    PH buffers are added before fermentation in the production of alcohol, m

  2. Using Mercury Standards in Trace Elemental Analysis

    Mercury testing is an incredibly important process for both product and environmental safety. Mercury can be a source of toxic pollution that is dangerous for both animal and human health. Mercury compounds can be found as part of hazardous air pollution or in water or soil sources.

     Mercury Needs to Be Regulated

    Due to the environmental and health dangers that mercury poses, the US Environmental Protection Agency (EPA) has strict regulations governing the reporting, inventory, and use of mercury-containing products.1 Mercury’s danger as an air pollutant means that to minimize the pollution from power plants, the EPA has announced it will reinstate regulation to the amount of mercury that can be released as part of coal-burning processes.2

     Other Forms of Legislation

    As well as the regulation affecting power plants and air pollution, there have been updates in 2020 to the EPA’s Clean Air Act as well as reporting previ
