Agilent HPLC System Corona Needle APCl

The Agilent G1947-20029 Corona Needle is a specialized component for Agilent Liquid Chromatography (LC) or Mass Spectrometry (MS) systems that utilize Atmospheric Pressure Chemical Ionization (APCI). In APCI, this needle generates a corona discharge, creating ionized gas molecules. As your liquid sample exits the LC column, it interacts with these ionized gas molecules, causing the sample itself to become ionized. This ionization process is critical for APCI-based LC/MS experiments, as it allows your mass spectrometer to detect and analyze the molecules in your sample.
