Connecting the nebulization gas to the nebulizer 2-19
Connecting the nebulization gas to the nebulizer
Insert the gas inlet tubing into the quick-disconnect tubing fitting on the
right-hand side of the nebulizer.
Connecting a column or second detector
Tips:
• If your system includes more than one detector, connect the ELS
detector so that it is the final detector in the series because it nebulizes
the column effluent and exhausts it as gas vapor.
• Do not allow solvent flow to continue if no gas flow is present.
Required materials
• Sample inlet tubing assembly
• 5/16-inch open-end wrench
To connect a column or second detector
1. Use the sample inlet tubing assembly supplied in the startup kit.
Caution:
To avoid contaminating the detector, connect the
chromatography system during operation. Gas flow in the nebulizer
creates a slight vacuum that can attract solvent or dust from the
detector's inlet port.
Caution:
In order to avoid particulate contamination, you should flush
any columns you are connecting to the detector before connecting them.
