    Nitrogen Blanketing

    Overview Nitrogen (N2) blanketing is a process by which nitrogen is added to fill the headspace (the area between the fill line of a tank’s contents and the top of the storage vessel) to eliminate oxygen and moisture from storage tanks. Nitrogen is commonly used to blanket due to its extremely low reactivity with other substances, as well as its availability and relatively low cost. ...

    Pulse-Flow Respirometers

    When operating in the aerobic mode, oxygen – from a supply of pure oxygen – is added in small increments into each respirometer vessel in response to oxygen uptake and carbon dioxide absorption. This mode of operation maintains a constant oxygen concentration in the headspace within the reaction vessel. Oxygen transfer from the headspace to the liquid phase is accomplished by using ...

    1-day Hands-on Solid-Phase Micro-Extraction (SPME)

    This one day course is spent learning the theory behind Solid-Phase Micro-Extraction (SPME) and how to modify samples to improve results, then using this knowledge to create SPME methods, analyse samples and experiment with parameters to see the effects. This course will cover Headspace-SPME and Immersion-SPME, SPME phases, SPME instrumentation & set up, maintenance and troubleshooting. It ...
