ATMOSPHERIC PRESSURE IONIZATION MASS SPECTROMETER (APIMS)
Atmospheric pressure ionization mass spectrometry (APIMS) can be used for air quality monitoring by measuring the concentration of organic compounds in the air, such as volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs). These compounds can be emitted from various sources, including industrial activities, transportation, and natural sources, and can contribute to air pollution and impact human health. APIMS can be used for air quality monitoring by first collecting air samples using a sampling device such as a sorbent tube or a filter. The sample is then introduced into an APIMS instrument, where it is ionized and analyzed using mass spectrometry techniques. The resulting ion spectrum can be used to identify and quantify the organic compounds present in the air sample.
APIMS is a powerful technique for air quality monitoring because it can detect a wide range of organic compounds, including those that are present in trace amounts. It is also relatively fast, sensitive, and specific, which makes it an effective tool for identifying sources of air pollution and assessing the impact of air pollution on public health. Our EXTREL™ VeraSpec™ Atmospheric Pressure Ionization Mass Spectrometer (APIMS) is designed for reliable and repeatable low parts-per-trillion detection limits for contamination control in Ultra-High Purity (UHP) gases used in semiconductor and other high-tech industrial applications.
Our VeraSpec Atmospheric Pressure Ionization Mass Spectrometer (APIMS) is a powerful tool used for monitoring airborne molecular contaminants (AMCs) in semiconductor manufacturing environments. Here’s how it works:
-
Sample Collection: Equipped with an inlet that draws in air from the semiconductor manufacturing environment. The air sample is then passed through a filter to remove any particulate matter and is directed to the APIMS system for analysis.
-
Atmospheric Pressure Ionization: Uses an atmospheric pressure ionization source to ionize the gas-phase molecules in the air sample. The ionization process generates both positive and negative ions, depending on the ionization conditions.
