Survey Says: Are You in the Market for a Gas Generator?
If you’ve had to lug a tank of gas to an experiment station and secure it in place, you know the hassle and danger involved. Many lab managers are turning to generators for convenience; cost also plays a part.
If you’ve had to lug a tank of gas to an experiment station and secure it in place, you know the hassle and danger involved. Many lab managers are turning to generators for convenience; cost also plays a part with labs needing to pay for the delivery of gas while the time required to change the tanks and the managerial costs of maintaining the necessary supply of tanks also hurt the bottom line. Most generators pay for themselves in two years on the hard costs alone and can also make a better product. When you generate gas at a plant, the second you start doing anything with it, the gas starts to degrade, even as the producer starts to fill a tank from a big supply. If users decide to go the gas generator route, they have plenty of options to choose from. One class, the zero air gas generator, makes air that is free of hydrocarbons, which is the kind of gas needed for many processes, including gas chromatography. Labs can also buy generators that make a specific gas, such as hydrogen or nitrogen.
