4.3 Safety and handling
Bear in mind the following safety considerations when performing maintenance procedures:
Warning:
To avoid personal contamination with biologically hazardous, toxic, and corrosive
materials, wear chemical-resistant, powder-free gloves when performing this procedure.
Warning:
Observe Good Laboratory Practice (GLP) at all times, particularly when
working with hazardous materials. Consult the Safety Data Sheets regarding the
solvents you use. Additionally, consult the safety representative for your organization
regarding its protocols for handling such materials.
Warning:
To avoid electric shock, observe these precautions:
• Do not remove the mass spectrometer’s protective panels. The components they
cover are not user-serviceable.
• When the instrument is in Operate mode, avoid touching the areas marked with the
high voltage warning symbol. To touch external areas marked with the symbol, first
put the instrument in Standby mode.
Warning:
To avoid burn injuries, take great care while working with the probe and
source; these components can be hot.
Warning:
To avoid puncture wounds, take great care while working with the source
enclosure open if one or both of these conditions apply:
• An ESI probe is fitted (the probe’s tip is sharp).
• A corona pin is fitted (the pin’s tip is sharp).
Warning:
To avoid injury, ensure that these criteria are met when performing
maintenance operations inside the source enclosure:
• The instrument is in Standby mode.
• LC flow is diverted to waste or set to Off.
• Desolvation gas flow is stopped.
for safety advisory information.
4.4 Preparing the instrument for working on the source
For safety reasons, you must follow this procedure before working on the source (for example,
when changing the probe or operating the source isolation valve), and when maintaining the
source.
