System Overview
14 Document Number: D1000092204 B
Interlocks (pressure switches) monitored by the firmware detect if the Curtain Gas
supply and the roughing pump are switched on. If the interlocks are not satisfied,
the turbo pumps are not initiated.
CAUTION! If the ion source is removed, the system electronics will be disabled,
interrupting any data acquisition tasks. The turbo pump and the vacuum system will not
be affected.
1. Turn on the roughing pump, if it was turned off. The power switch is
located beside the power supply input attachment on the roughing
pump.
2. Make sure that all gas supplies are flowing correctly to the instrument.
3. Plug the mains power cord into the bulkhead.
4. Turn on the main power switch.
5. Make sure that the GPIB (general purpose interface bus) cable is
connected to both the instrument and the computer.
6. Turn on the computer, if it was turned off, and then start the Analyst
®
software.
Instrument Safe Fluids
The following fluids can safely be used with the instrument:
• Methanol (0 to 100%)
• Acetonitrile (0 to 100%)
• Water
• Formic acid (0 to 1%)
• Ammonium acetate (0 to 1%)
Source/Gas Parameters
The parameters in Table 1-1 are optimized for different LC conditions involving
flow rate. For more information about the parameters, see the Analyst
®
software
Help system.
Note: The roughing pump has its own power toggle switch and must be turned
on manually. The roughing pump is not controlled remotely by the system
controller.
Note: This list is not complete. If you are uncertain about a specific fluid, do not use the
fluid until confirmation is received from AB SCIEX that it will not present a hazard.
Note: We recommend that you run the instrument with the Curtain Gas™ flow set to at
least 20 to maintain good instrument performance.
