  Found in all proteins and living organisms, nitrogen is an essential chemical element. In laboratories, gaseous and liquid nitrogen is used for a wide range of applications across a myriad of industries. These include pharmaceutical research, healthcare, food analysis, chemicals and bio-tech. Traditionally, nitrogen has been accessed via pressurised gas cylinders. However, over the past decade, an increasing number of laboratories have made the switch to nitrogen gas generators. Compact, reliable and efficient, these systems allow laboratory personnel to generate pure, lab-quality nitrogen in seconds. Below, we take a look at some of the most common applications for nitrogen generators in laboratories. ​ Drug detection in clinical samples On-site gas generators provide technicians with nitrogen needed to operate Liquid Chromatography-Mass Spectrometry (LC-MS) instruments. Used to separate and identify compounds, LC-MS is a powerful analytical technique suitable for both simple an...

  Pressure Swing Adsorption (PSA) nitrogen generators operate based on the principle of separating gases using a physical process called adsorption. This technique utilizes solid materials known as adsorbents to capture and hold specific components from a gas mixture. PSA Nitrogen Generators The use of adsorption-based technology for converting compressed air into nitrogen is a well-established and widely utilized method across various industrial sectors. PSA (Pressure Swing Adsorption) nitrogen generators are especially valued for producing high-purity nitrogen, which is essential in applications ranging from food packaging to analytical instruments like Liquid Chromatography Mass Spectrometry (LC-MS) and Gas Chromatography (GC). These  nitrogen generators  are engineered to deliver consistent nitrogen purity by alternating pressure levels within two adsorption vessels filled with specialized adsorbent materials. While one vessel is actively separating oxygen, moisture, ...
