      SilcoNert® - Better performance, better results.

      Matt Shaw

      What is it?

      SilcoNert® is a non-reactive silicon coating process that makes flow paths inert for better process control, consistent sampling, and analytical results. The patented chemical vapor deposition process bonds the coating to stainless steel; alloy; ceramic; and glass, making a high-tolerance, durable coating even under extreme temperatures and pressures.

      SilcoNert® is made by SilcoTek Coatings, "the world's leading provider of high performance inert coatings applied by chemical vapor deposition (CVD)."

      Risks & Hazards of Mercury

      Matt Shaw

      What is Mercury?

      Mercury is a naturally occurring chemical element found in rock in the earth's crust, including in deposits of coal.  On the periodic table, it has the symbol "Hg" and its atomic number is 80. It is released into the environment from volcanic activity, weathering of rocks and as a result of human activity.

      Xenon - Gas Hazards & Applications

      Matt Shaw

      561px-Xenon-tetrafluoride-3D-vdWWhat is Xenon?

      Pronounced "ZEE-non," Xenon is a noble gas and is odorless, colorless, tasteless and chemically non-reactive. While not toxic on its own, its compounds are strong oxidizing agents that are highly toxic.

      Many compounds of xenon are created principally with fluorine or oxygen. Both oxides, xenon trioxide (XeO3) and xenon tetroxide (XeO4) are highly explosive. Some toxic compounds created with fluorine include difluoride, xenon deuterate, sodium perxenate, xenon hydrate, tetrafluoride and hexafluoride.

      Why does temperature affect your gas mixture?

      Matt Shaw

      A calibration gas standard is a homogeneous mixture of components that have the same proportions of its components throughout a given sample.

      Carbon Monoxide (CO) - Gas Hazards & Workplace Safety

      Matt Shaw

      Gas Chemical Details

      Carbon Monoxide is a colourless, odourless gas, to the human senses it is completely invisible. Carbon Monoxide is a highly toxic gas.  It is termed a toxic (blood) asphyxiant, meaning it reduces the oxygen transport properties of the blood.  Low ppm doses of Carbon Monoxide can cause headaches and dizziness, if the victim is removed to fresh air no permanent damage will result. High concentrations however, can saturate a person's blood in a matter of minutes and quickly lead to respiratory arrest or death.

      Occupational Health Risks of Carbon Dioxide

      Matt Shaw

      Gas Chemical Details

      Carbon Dioxide.jpgDespite the fact Carbon Dioxide is naturally present in the atmosphere (about 400ppm) and we exhale it when breathing, CO2 is one of the most frequently overlooked toxic gases. Both colourless and odourless, CO2 in high concentrations poses an extremely dangerous hazard.

      Carbon dioxide is heavier than air, with a density of 1.5 times that of fresh air. When it is released into an enclosed or confined space it tends to settle to the bottom, reaching the highest concentration in the lowest parts of the space.

      Oxygen (O2): Gas Hazards & Occupational Health

      Matt Shaw

      Gas Chemical Details

      Oxygen, the most abundant element in the earth’s crust is of great interest due to the fact that it’s essential in the respiratory processes of most living cells. It is found in both the air we breathe and the water we drink. In normal conditions oxygen is a colourless and odourless.

      Calibration Gas Selection: What’s a "pentane equivalent" calibration?

      Matt Shaw

      Calibration gas selection is critical in the operation of any combustible gas detector.

      A combustible gas detector will respond to a wide variety of ignitable gases and vapours. How the sensor responds is directly dependent upon which gas is selected to calibrate the instrument.
