Ammonia is a compound of nitrogen and hydrogen with the formula NH₃. A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct characteristic of a pungent smell.
About 80% of the ammonia produced by industry is used in agriculture as fertilizer. Ammonia is also used as a refrigerant gas, for purification of water supplies, and in the manufacture of plastics, explosives, textiles, pesticides, dyes, and other chemicals.
Calibration frequency is one of the most commonly asked questions regarding the use of gas detection instruments. Regulatory agencies typically refer users to follow manufacturers recommended protocols for calibration.
Plant rooms are often situated underground. This is by design to save space or by virtue of being built into existing basements or chambers. Underground Plant Rooms often contain an array of machinery such as Pumps, Boilers, Sprinkler Systems or Generators.
Battery banks are used to store energy generated by renewables, emergency power in data centres and motive power for electric forklifts and carts etc . The need for gas monitoring occurs while these batteries are being charged. Typically, batteries are continuously trickle charged. After heavy battery use or discharge, a higher charge voltage is used to quickly restore the batteries to full capacity. This charging process generates hydrogen gas which is emitted into the battery storage / recharge room. The faster the charge rate is, the higher the hydrogen generation rate.
There is much interest in power-to-gas (P2G), a technology where surplus power from solar power or wind generation is used to synthesize hydrogen, which can then be converted to fuel gas for storage or consumption.
Li-ion battery electrodes are manufactured by casting a slurry onto a metallic current collector. The slurry contains an active material, conductive carbon, and a binder. The binder is pre-dissolved in a solvent, most commonly N-Methyl-2-pyrrolidone (NMP). After mixing, the resulting slurry is cast onto the current collector and then dried. Evaporating the solvent to create a dry porous electrode is needed to fabricate the battery. Drying can take a wide range of time with some electrodes taking 24 hours at more than 120 °C to completely dry.
Laboratories regularly use inert gases in a number of applications. Helium and Argon, for example, provide a stable inert atmosphere within glove-boxes by purging the Oxygen. In addition they provide the same function in Additive Manufacturing (AM) machines and 3D printer chambers. Liquid Nitrogen is also used to provide temperatures as low as -196°C . This makes it ideal for use in Cryo-biology, Cryo-Surgery and General Cryogenic research.
Commercial, Industrial and Manufacturing Facilities have dedicated Boiler Rooms to house their mechanical equipment and other associated machinery.
In August 2018 the new EH40 Workplace Exposure Limits (WELs) for Toxic Gases were published. These include a reduction in the limits for Carbon Monoxide (CO) .Carbon Monoxide Long Term (8 Hour) Exposure Limit (LTEL) is now 20ppm and the Short Term (15 Min) Exposure Limit (STEL) is now 100ppm.
