The document introduces the features and characteristics of Agilent 500 Ion Trap LC/MS Atmospheric Pressure Ionization Interface, including electrospray assembly, liquid capillary, tilted chamber and tilted ion guide.
The document provides a technical overview of the Agilent 500 Ion Trap LC/MS Atmospheric Pressure Ionization (API) interface. It describes how ions formed at atmospheric pressure in the electrospray assembly are directed into the low-pressure region of the mass spectrometer vacuum system via an interface capillary and transported by a hexapole ion guide.
One thousand consecutive injections showed no indication of contamination or changes in system sensitivity.
It is designed to meet the challenge of routine analysis of large numbers of samples in a dirty matrix.
One thousand consecutive injections were made with the results shown in Figure 4.
The %RSD for the area response was 10.0% after 1000 injections.
