6 Installing the
Valve/Pump Module
Once the autosampler is prepared for use, the ASXPRESS PLUS valve/pump
module should be connected to the autosampler and to the nebulizer of your
spectrometer.
All tubing (except the sample loop and probe) is pre-connected to the ASX
PRESS
PLUS valve/pump module to allow convenient inter-connection to the
autosampler and to the nebulizer per Figure 6-1. The 6-Port valve ports are
numbered, color coded, and labeled with a descriptive definition providing
clear identification of port functionality. The only connection required at the
ASX
PRESS PLUS 6-Port Valve is the customer-selected sample loop. All other
ASX
PRESS PLUS plumbing is prepared to be connected to the autosampler and
ICP/ICP-MS as received in the shipping packaging.
NOTE
All fitting connections on the 6-Port Valve are to be finger tightened only to
prevent damage to the valve and tubing. Do not overtighten.
The plumbing connections should be made without using tools. In fact, using
tools such as screwdrivers or pliers to perform installation tasks may result in
a damaged or unusable instrument. Do not tighten fittings with anything other
than your fingers.
