Note<br />
For critical sampling applications,<br />
consider replacing the<br />
suction line, pump tube, and<br />
discharge tube. Replacement<br />
eliminates the possibility of any<br />
cross contamination from previous<br />
sampling sites.<br />

CLEANING PROTOCOLS FOR PRIORITY<br />
POLLUTANTS<br />
Clean sampling equipment is essential for valid laboratory analysis.<br />
<strong>Isco</strong> recommends that you develop cleaning protocols in consultation<br />
with a laboratory analyst when designing the<br />
monitoring program. For example, to clean sample bottles, suction<br />
line, and pump tubes, Lair (1974) suggests these protocols used by<br />
USEPA Region IV Surveillance and Analysis field personnel<br />
engaged in NPDES compliance monitoring. The protocols are<br />
based on U.S. Environmental Protection Agency Publications<br />
EPA-600/4-77-039 (Sampling of Water and Wastewater by Dr.<br />
Phillip E. Shelley).<br />
<strong>Isco</strong> Glass Sample Bottles<br />
1. One spectro-grade acetone rinse.<br />
2. Dishwasher cycle (wash and tap water rinse, no detergent).<br />
3. Acid wash with at least 20 percent hydrochloric acid.<br />
4. Dishwasher cycle (wash and tap water rinse, no detergent).<br />
5. Replace in covered <strong>Isco</strong> tubs.<br />
Vinyl Suction Line<br />
1. Use new suction line for each new sampling setup, therefore,<br />
no cleaning is required.<br />
2. Use Teflon suction line when sampling for organic compounds.<br />
Teflon 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 air<br />
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 Tube<br />
1. Rinse by pumping hot tap water through the tube for at least 2<br />
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 minutes.<br />
3. Rinse by pumping hot tap water through the tube for at least 2<br />
minutes.<br />
4. Rinse by pumping distilled water through the tube for at least<br />
2minutes.<br />
