Gas chromatography columns known as capillary columns are frequently used in analytical chemistry and biochemistry for the separation and analysis of many types of chemicals. When compared to broader columns, these columns' thin interior diameter, which is typically between 0.1 and 0.5 millimeters, provides for greater separation efficiency and sensitivity.

The excellent resolution of capillary columns is one of its main benefits. More effective separation of compounds is achieved thanks to the tiny internal diameter of the column, which increases the surface area of the stationary phase in contact with the sample. Additionally, the narrower columns' diameter lessens band-broadening effects, which can enhance peak forms and make it easier to distinguish individual components in complex mixes.

Because they can be utilized with a variety of stationary phases and sample types, capillary columns are also very adaptable. They are therefore perfect for analyzing complicated combinations like those in medications, biological fluids, and environmental materials. Additionally, because they are less prone to contamination and require less upkeep, capillary columns are frequently more resilient and long-lasting than conventional packed columns.

Principle of LC/MS Nitrogen Generators

The use of membrane technology in LC/MS nitrogen generators produces high-purity nitrogen gas for use in LC/MS (liquid chromatography-mass spectrometry) applications. The procedure can be divided into the following steps:

  • Through a compressor, the air is sucked into the generator and filtered to eliminate moisture and pollutants.
  • The nitrogen molecules are separated from other gases like oxygen and water vapor as the compressed air is passed through a selectively permeable membrane.

The following are some of the main ideas guiding the utilization of nitrogen generators in LC/MS:

  • Purity

Nitrogen produced by quality LC/MS nitrogen generators has a high purity, often 99.5% or higher. As gas contaminants can interfere with the ionization process and result in inaccurate data, doing this is crucial for assuring accurate and reliable mass spectrometry results.

  • Efficiency

Nitrogen generators are made to be extremely efficient, using little energy and producing little waste. They are therefore a more affordable and environmentally responsible option than conventional nitrogen gas cylinders.

  • Convenience

Nitrogen generators are an easy and dependable supply of nitrogen gas for LC/MS applications since they may be placed on-site and require no maintenance.
