Keeping safe with mercury vapour indicators


effect on 1 April 2020, Purolite Corporation China is using a Mercury Vapour Indicator (MVI) from global gas detection instrumentation manufacturer, ION Science to help ensure the health and safety of its employees. The handheld instrument is measuring mercury vapour levels in an area used for mercury intrusion porosimetry to calculate the porosity of speciality ion exchange resin. Purolite is a leading manufacturer of quality ion exchange, catalyst, adsorbent and speciality high-performance resins for complex regulatory environments including biotechnology, pharmaceutical, food, fine chemical and electric power generation. The company focuses 100 per cent of its resources on the development and production of resin technology. Xihua Yu, Purolite’s lab instruction engineer comments: “As part of our quality control process, we conduct mercury intrusion porosimetry to measure the porosity of our resin. This is because the porosity of a material not only affects its physical behaviour but also its durability and decay rate.” He continues: “In line with the requirements of the newly updated ‘occupational exposure limit of hazardous agents in the workplace’ GBZ 2.1-2109 regulations, it is important we monitor the mercury vapour concentration in the area where the porosimeter instrument is located to ensure the health and safety of our staff.” In accordance with the Chinese regulations,


short term exposure limit of hazardous agents in the workplace is mercury vapour: 0.040mg/m3 “We chose the ION Science MVI over
