3 • Operation and Maintenance
This chapter describes routine operating and maintenance procedures for the
Dionex AS-DV.
3.1 Preparing the Sample Vials
Thermo Fisher Scientific recommends thoroughly rinsing all PolyVials and caps
with deionized water before filling to remove any traces of dust. Thermo Fisher
Scientific DOES NOT recommend reusing vials or caps and does not guarantee
their cleanness or proper operation if reused.
When performing trace-level analyses, use the procedure in Section 3.1.1 to clean
the vials. To clean the caps, use either the procedure in Section 3.1.2 (for caps
without filters) or Section 3.1.3 (for caps with filters).
NOTE Before cleaning, inspect each vial and cap for
damage (nicks, scratches, etc.).
3.1.1 Cleaning the Vials
1. Rinse the vials 10 times with a jet of deionized water.
2. Place the rinsed vials in a vial tray (for 0.5 mL vials, P/N 068948; for
5.0 mL vials, P/N 068947) and fill them to the top with deionized
water. Do not touch the tops or interiors of the vials with your fingers.
3. Allow the vials to soak for a minimum of 24 hours (48 hours, if
possible).
4. When you are ready to use a vial, empty it, and then rinse it 10 times
with a jet of deionized water. Shake out any excess water and then
rinse the vial twice with aliquots of sample.
To prevent the introduction of contaminants onto the vials and filter
caps, extreme care must be used in cleaning. Use only ASTM Type I
(18 megohm-cm) filtered and deionized water that meets the
specifications listed in
Table 1-1 for the following cleaning
procedures.
