Chip bags have all that air in them for a valid reason — and it’s not air, anyway, it’s nitrogen gas. So what is this gas doing in your bag of crisps? First, the gas acts as a preservative so your chips are as crispy when you open the bag as the day they were […]
Gas chromatography is a process used to separate chemical compounds for analysis. The analytical chemistry process is used with gases that won’t decompose when vaporized. Gas chromatography are used in a wide range of industries — everything from forensic science to medical marijuana. While the procedure is highly useful, there are risks when working with nitrogen gas. […]
If you’ve ever remarked on the smooth creaminess of a pint of Guinness, you’ve picked up on the key difference in its carbonation: Nitrogen rather than carbon dioxide. Such “nitro” beers have become a trend in recent years, with major U.S. breweries and small startups alike offering nitro products. Nitrogen keeps bitterness in check and […]
A blend of gases — carbon dioxide, oxygen, and nitrogen — help preserve packaged food by reducing the amount of oxygen inside the sealed package. Gas flushing or Modified Atmosphere Packaging, as the process is called, also reduces the amount of processing that food must undergo. This preserves the quality and nutrient content of meats, […]
Liquid nitrogen is used in a broad range of industries, from steelmaking and pharmaceutical to health care and ceramics. The inert gas is also used in laboratories, breweries, fine cooking, and more. Wherever liquid nitrogen is used, it must be stored securely so as not to mingle with air. Learn why nitrogen must be so carefully contained […]
Nitrogen has many uses in industrial applications where oxidation would be undesirable. From carbonizing beer to preserving food, reducing fire danger, and cleaning equipment, nitrogen is a safe, inexpensive gas. For companies that need a steady supply of nitrogen gas, nitrogen generators work well. Learn about the uses of nitrogen generators and why you should use […]
Carbon dioxide, in its solid form, is colder than ice. It is so cold, in fact, that handling it without protection can cause frostbite. It does not melt, but instead dissipates into a gas that can be dangerous to breathe. This substance is called dry ice, and, when handled properly, has many useful applications. The […]
Highly effective, field-proven system for helping control hydrogen sulfide (H2S) emissions from municipal waster water treatment plants is now available from PureAire Monitoring Systems. Designed for use in 100% condensing RH environments, the PureAire Chlorine Monitor responds almost instantaneously to changes in chlorine concentration, making it ideal for controlling the addition of H2S oxidizers such […]
An extremely sensitive monitoring system for the detection and measurement of fluorine (F2) is available from PureAire Monitoring Systems. Ideal for monitoring scrubbers, exhaust stacks, process areas, and other locations where fluorine may be present, the PureAire Fluorine Monitoring System measures concentrations as low as 50 PPB, yet will not react to hydrogen or alcohol-based […]
