liquid nitrogen is a cryogenic fluid that is commonly used in laboratories and industrial applications. It has a boiling point of -195.8°C (-320.4°F), which is lower than the freezing point of most gases.
As you already know, freeze drying (also known as lyophilization or cryodesiccation), is a low temperature dehydration process which involves freezing the product, lowering pressure, then removing the ice by sublimation.
The use of nitrogen gas in the ionization source of a mass spectrometer ensures stable operating conditions, reduces unwanted background ions, and aids in the efficient transfer of ions for analysis.
We are proud to introduce you a new accessory for XELSIUS: the Pressurized Reactor. You can now conduct your reactions under pressure and obtain results more quickly.
