  • Nitro Beer Tastes Better

    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 balances out the hops to make drinkable craft brews, but it ...

  • How Does a Gas Analyser Work?

    Whatever you want to detect, you need to identify a property of the object that is easy-enough to measure. When it comes to monitoring and analysis of gaseous species (atoms or more commonly molecules), it turns out that it often is possible to utilize the optical properties of the gas. You need a light source, a light detector, and a characteristic behaviour of the gaseous species in question ...
