Field Testing vs Laboratory Analysis

Field kits provide fast operating information, while laboratories provide broader capability, traceability and confirmatory analysis.

Practical guidance

Use field testing for routine control, immediate decisions and trend monitoring. Use approved laboratory methods for compliance, validation, disputes, very low detection limits and critical confirmation.

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.
