Zero air refers to air that has been purified to an extremely high degree. To be classified as zero air, it must contain less than 0.1 parts per million (PPM) of total hydrocarbons. Hydrocarbons are compounds composed solely of hydrogen and carbon atoms. They are the primary components of natural gas and petroleum. For example, methane (CH₄) is a hydrocarbon with one carbon atom and four hydrogen atoms, while propane (C₃H₈) and ethane (C₂H₆) are also hydrocarbons.
High-quality zero air generators can produce a continuous flow of dry, clean air with extremely low hydrocarbon content (less than 0.05 ppm). These generators can extract ultra-clean air from an existing compressed air supply. They are commonly used to supply zero air for gas chromatography (GC-FID, FPD, NPD), liquid chromatography-mass spectrometry (LC/MS), and gas sensing applications.
Zero air is commonly used as a carrier gas in gas chromatography. GC is an analytical technique that separates and analyzes volatile compounds in a sample. The purity of the carrier gas (such as zero air) is crucial for accurate results.
In GC-FID, zero air serves as the makeup gas for the FID. The FID detects hydrocarbons by measuring the ionization of carbon atoms in the sample. Using zero air ensures minimal interference from background hydrocarbons.
Similar to FID, NPD is another type of detector in gas chromatography. It specifically detects nitrogen- and phosphorus-containing compounds. Zero air is essential for maintaining a clean background signal.
In LC/MS, zero air is used to create a clean environment for ionization and mass analysis. Impurities can affect the sensitivity and accuracy of mass spectrometry results.
Zero air is employed in air quality monitoring stations to calibrate instruments and measure pollutant levels. It ensures accurate readings by minimizing interference from hydrocarbons.
Many analytical instruments, such as spectrophotometers and atomic absorption spectrometers, require zero air for calibration. Precise calibration ensures reliable measurements.
