Ultra-high-purity gas mixing and blending is vital to an extremely broad cross-section of market areas. Although it sounds simple enough, there is more to gas blending than simply mixing distinct streams of pure constituent gases– particularly where ultra-high purity is necessary. There are several different methods of gas blending, each of which has different underlying workingRead More
The most common air pollutants include carbon monoxide, ground level ozone, nitrogen oxides, particulate matter, sulfur oxides, and volatile organic compounds. There are other pollutantsRead More
Monitoring the composition of ambient air is a vital process in maintaining the quality of the air we breathe. The World Health Organisation (WHO) has attributed millions of deaths per year to air pollution and inhalation of industrial particulates emitted by vehicles and industrial plants. New research has underlined the severity of the issue, suggesting that the health impacts associated with polluted air are more severe than previously believed. The European Heart Journal estimates that air pollution reduces the mean life expectancy in Europe by approximately 2.2 years.
Ozone (O3) is subcategorized into three primary groups; stratospheric, tropospheric, and artificially-manufactured ozone. Stratospheric ozone is a naturally-occurring substance that forms in the upper stratosphere, up to sixty miles above the earth’s surface. Ultraviolet (UV) rays cleave oxygen (O2) molecules into individual atoms, and when these free atoms bind to whole O2 molecules, ozone isRead More
