Water Sampling Best Practices

Sampling errors can be larger than the analytical error, so consistent collection is essential.

Practical guidance

Select representative points, flush stagnant lines where required, avoid dirty containers, prevent contamination, analyse unstable parameters promptly and document the sample location and conditions.

Recommended workflow

Define the parameter and purpose of testing.
Select a representative sample point.
Confirm the expected concentration range.
Read the kit instructions before starting.
Use clean apparatus and fresh reagents.
Record the result and compare it with previous readings.
Confirm unexpected or critical results when necessary.
