5.2 Shutting Down the ASXPRESS Rapid Sample
Introduction System
To shut down the ASXPRESS Rapid Sample Introduction System, complete the
following steps:
1. Drain the system by removing the rinse solution uptake tubing from the
rinse solution sources (autosampler and ICP/ICP-MS). Operate the
autosampler peristaltic pump and ASXPRESS vacuum pump by operating
the “manual cycle” function or by using the manual function for
operating the autosampler peristaltic pump (both from within the
Xpress Configuration Tool software) and manually running the ICP/ICP-
MS peristaltic pump until all solution drains from the tube attached to
the rinse station outlet, the vacuum pump waste discharge, and from
the ICP/ICP-MS nebulizer drain.
Note:
If using a rinse solution other than deionized water, flush the rinse
system with deionized water before shutting down and/or draining the
ASXPRESS discrete Sampling Accessory. For more information, see the
following section, “Flushing the Rinse Station and Flow Path”.
2. Switch the power switch on the back of the autosampler to “Off.”
