Lab water system calibration procedures
Lab water system has no instrument calibration of its own in most labs. Its performance is controlled through qualification (below) and the system suitability or acceptance checks of each test that uses it.
Instrument qualification (DQ · IQ · OQ · PQ)
- 01
DQ — Design qualification
Defines water grade, daily volume, feed water quality, monitoring (resistivity, TOC) and data recording needs.
- 02
IQ — Installation qualification
Confirms installation, feed water and drain connections, consumables, serial numbers and documentation.
- 03
OQ — Operational qualification
Verifies resistivity, TOC, flow rate and alarms meet specification, and checks sensor accuracy.
- 04
PQ — Performance qualification
Monitors water quality (resistivity, TOC, microbial counts where needed) over a defined period of routine use.
Keep every Lab water system in control: usage logs, calibration and maintenance schedules, and automatic blocking of overdue instruments.
