4.23.1 Removing the UniSpray probe assembly
Required materials
• Chemical-resistant, powder-free gloves
Warning:
To avoid personal contamination with biologically hazardous, toxic, and corrosive
materials, wear chemical-resistant, powder-free gloves when performing this procedure.
To remove the UniSpray probe assembly:
1. To prepare the instrument for working on the source, stop solvent flow, ensure that the
instrument is in Standby mode, and stop desolvation gas flow.
Warning:
