1. Introduction
1.1 General Information
This standard operating procedure (SOP) defines the procedure for the installation
qualification, operation qualification and performance verification (IQ/OQ/PV) of Agilent 3200
series meters. This procedure provides a guideline to generate the data necessary to validate
or qualify the Agilent 3200 series meters.
This SOP is applicable to all Agilent 3200 series meters that are used in a regulated lab. And
this SOP can be used as a reference for customer to develop their own IQ/OQ/PV documents.
It’s customers’responsibility to develop and maintain the IQ/OQ/PV SOP for their specific
applications.
1.2 Meter Information
Installation qualification and operation qualification are required for all new meters used in a
regulated environment. The meters will not be released for regulated use until the installation
qualification and operation qualification have been performed with passing result.

Page 9 of 13
Thoroughly rinse the DO probe with DI water; Dry it with a soft tissue on the
membrane surface. To calibrate with air, put the probe in a well-ventilated area.
OR calibrate with water saturated with air as below,
Swirl the probe at a speed of 20–80 cm/s or stir the water to produce a similar linear
speed. Keep the flow speed constant during calibration. Ensure there is no air bubble
trapped under the membrane.

probe to remove bubbles on the gas permeation membrane surface; From the initial
state or while measuring, press [Calibrate]; Select Calib Zero; Press [Enter] to
select Zero Point Calibration. When reading becomes stable, press [Enter] to
automatically record the Zero Point value. This ends Zero Oxygen Calibration.

temperature compensation.
Rinse the conductivity probe with distilled or DI water. Soak the conductivity probe in
the standard solution.

sample.
Set the cell constant to the value written on the probe label or recalibrate the probe to
get a new cell constant in 3.7.2.
Press [Calibrate] and select TDS Factor. Press [Enter] to enter Calibration mode.
Rinse the conductivity probe with DI water.
The temperature of the calibration solution should be 25.0 ± 0.1 °C.
Soak the conductivity probe in the standard solution.
Press [Setup].
Enter an STD value (mg/L) given in Table 6 on page 41 of 3200 C User Guide.
When the reading becomes stable, press [Enter].

The meter automatically calculates and sets a new TDS factor. Calibration is done.
4. Performance Verification
For performance verification, evaluation of accuracy, inter-assay RSD and intra-assay RSD
will consist of at least three measurement sets. Each set will measure pH of three test
samples representing low, medium and high pH value. The test buffers were the same as the
standard buffers. To evaluate precision of the inter-assay and the intra-assay, three
measurement sets must be conducted in three different days. The acceptance criterion is
bracketed in the table in appendix document.
The accuracy and the precision of pH meter should be validated. Measure three testing
buffers. Each buffer is measured six times continuously. Repeat the procedure three times;
each repeat should be at least 24 hours apart. Calculate intra-day and inter-day RSD%.
