–Conductance by Conductivity Meter (EPA 120.1)
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.
– Methods for the Chemical Analysis of Water and Wastes (MCAWW) (EPA/600/4-79/020)
|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.|
|Sample Volume||250mL HDPE bottle|
|Method Refernce||EPA 120.1|
