move the probe (“sipper”) up and down, and move the probe to a sample vial
and back.
Refer to the QuickTrace software online help for more information on how to
control the autosampler.
Step 12: Fill the Rinse Solution Bottle
1 Fill the rinse bottle with trace metal grade 1% HCl / 2% HNO 3 v/v.
NOTE:
When analyzing samples and standards of high concentration such as 20 ppb
or greater use a stronger concentration of acid; such as 5% HCl / 2% HNO 3 or a
similar mix but do not exceed 10% HNO 3 .
2 Insert the rinse solution drain tube (from the autosampler rinse station drain
port, via the peristaltic pump) about ¼ of the height of the rinse bottle.
3 Insert the rinse solution supply tube (to the autosampler rinse station intake
port, via the peristaltic pump) so that it is just above the bottom of the rinse
bottle.
The end of the drain tube must remain above the end of the supply tube.
For help identifying the rinse solution drain and supply tubes, see Figure 3-10
on page 30.
