Compressed gases such as zero air, nitrogen and hydrogen are commonly used in the laboratory for a broad range of instrumentation including GC with FID, LC-MS and FTIR. In many laboratories, the compressed gas source is a high pressure gas cylinder. Handling…
There are a wide variety of carrier gases potentially available for use with gas chromatography (GC) systems, including helium, hydrogen, and nitrogen. Your range of choices, however, may be limited by a number of factors that include detection method…
Laboratories around the world require a reliable and consistent mixture of quality gases for a range of applications including gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). In an environment where safety is paramount, gas…
Food suppliers are always seeking ways to extend shelf life. Improved shelf life allows manufacturers to extend their geographical reach and allows the product to remain in stores and consumer's homes longer. Modified Atmosphere Packaging (MAP) is…
Gas chromatography (GC) uses a wide range of gases including helium, hydrogen, and nitrogen as the carrier gas. The most common carrier gas is helium. In recent years, however, the availability of helium has decreased and its cost has increased significantly…
Power generation plants rely heavily on demineralized and deionized water to maintain required levels of water purity during process operations. Managing the water supply is critical under normal operating conditions, as well during outages. The introduction…
A question that is frequently asked when considering the installation of a nitrogen gas generator is "will the system create an oxygen-rich or oxygen-deficient atmosphere that could be potentially hazardous?"
Noise pollution in the laboratory, as in any workplace, is a serious health concern. That’s according to the US Occupational Health and Safety Administration (OSHA) whose role it is to enforce the 
A critical factor in the design and operation of any laboratory is the amount of noise the people who work there are exposed to throughout the day. Various agencies including the 
Laboratory equipment can be a significant contributor to workplace noise levels, which the US Occupational Health and Safety Administration (OSHA) has identified as a serious health concern. Depending on the type of lab, noise can come from many sources…
The cost and supply of Helium has caused chromatographers to use Nitrogen gas generation as a cost effective alternative.
A question often asked in the wine and grape industry is: which is better for wine production, nitrogen or argon? Both are inert gases at room temperature, and both are used for blanketing wine and flushing or purging tanks.
