Specific Conductance
–Conductance by Conductivity Meter (EPA 120.1)
Scope:
This method determines conductance of drinking, surface, and saline water, domestic and industrial wastes and acid rain (atmospheric deposition).
The specific conductance of a sample is measured by use of a self-contained conductivity meter, Wheatstone bridge-type, or equivalent. Samples are preferable analyzed at 25oC. If not, temperature corrections are made and results reported at 25oC.

Method Data
| Method 120.1 | |
|---|---|
| Hold Time | 24 hours, unpreserved, 28 days preserved |
| Preservation | Analyses can be performed either in the field or laboratory. If analysis is not completed within 24 hours of sample collection, sample should be filtered through a 0.45 micron filter and stored at 4oC. Filter and apparatus must be washed with high quality distilled water and pre-rinsed with sample before use. |
