Conductivity Testing

Conductivity testing is offered in our Environmental department for dialysis water or drinking water samples. This test is applicable for non-New York potable water samples.

  • Collect water sample in a Water Analysis Tube (50 mL trace-metal free tube).

  • Minimum water sample volume of 20 mL.
  • Secure lid.
  • Use the bar code label to identify the specimen.
  • Place the labeled bottle in a plastic Transport Bag with an absorbent sheet and seal shut.
  • Refrigerate at 2°- 8° C.
  • Estimated Total Dissolved Solids (TDS) can be measured by multiplying conductivity results by 0.55.
