<strong>Glacier</strong> <strong>Transportable</strong> <strong>Sampler</strong><br />
Section 5 Maintenance<br />
PTFE Suction Line<br />
1. Rinse twice with spectro-grade acetone.<br />
2. Rinse thoroughly with hot tap water using a brush, if possible,<br />
to remove particulate matter and surface film.<br />
3. Rinse thoroughly three times with tap water.<br />
4. Acid wash with at least 20 percent hydrochloric acid.<br />
5. Rinse thoroughly three times with tap water.<br />
6. Rinse thoroughly three times with distilled water.<br />
7. Rinse thoroughly with petroleum ether and dry by pulling<br />
air through the line.<br />
8. Dry overnight in a warm oven (use an oven temperature of<br />
lower than 150 degrees F), if possible.<br />
9. Cap ends with aluminum foil.<br />
<strong>Isco</strong> Pump and Discharge Tubes<br />
1. Rinse by pumping hot tap water through the tube for at<br />
least 2 minutes.<br />
2. Acid wash the tube by pumping at least a 20 percent solution<br />
of hydrochloric acid through the tube for at least 2<br />
minutes.<br />
3. Rinse by pumping hot tap water through the tube for at<br />
least 2 minutes.<br />
4. Rinse by pumping distilled water through the tube for at<br />
least 2 minutes.<br />
Note<br />
For critical sampling applications, consider replacing the suction<br />
line, pump tube, and discharge tube. Replacement eliminates<br />
the possibility of any cross contamination from previous<br />
sampling sites.<br />
5.3 Defrosting the <strong>Glacier</strong><br />
Refrigerated<br />
Compartment<br />
Defrosting the refrigerator compartment may be necessary,<br />
depending on the humidity of its operating environment. If ice<br />
forms on the walls of the interior compartment, never use sharp<br />
objects to remove it. Instead, simply remove power and allow the<br />
ice to melt. Mop up the ice-melt with a towel, or drain it by<br />
briefly tipping the <strong>Glacier</strong> over.<br />
CAUTION<br />
Positions other than the <strong>Glacier</strong>’s normal upright position will<br />
drain the lubricant away from the refrigerator compressor.<br />
Operation without adequate lubrication may permanently damage<br />
the refrigeration system. If the <strong>Glacier</strong> is turned over for<br />
more than a few seconds, the <strong>Glacier</strong>’s refrigeration system<br />
must not be operated for at least one hour after returning the<br />
<strong>Glacier</strong> to its upright position.<br />
