5 Before connecting gas

5.1 Necessary considerations before gas connection

With standard flow-through configuration, the GPR-x500 analyzers are designed for positive pressure
samples and require connections for incoming sample and outgoing vent lines.

Your analyzer is equipped with two gas ports as shown in Figure 7.

Figure 7. Gas ports (right elevation)

Figure 8. Gas ports: sample system (bottom elevation)

The inlet and outlet vent gas lines require 1/4” stainless steel compression type tube fittings.

The sample inlet tubing must be metallic, preferably stainless steel (SS). The sample vent line may be
of SS or hard plastic tubing with low gas permeability.

ProcessSensing.com 15

To ensure the best possible operation, a review of the installation is recommended:

a. Sample gas quality

• Is the sensor suitable for gas?

• Is a gas scrubber required?

• Is the sample gas clean and liquid free?

b. Stainless steel tubing (essential for maintaining the integrity of the gas stream for very low ppm

or % level analysis.

NOTE: If operated in potentially contaminated gases, which can interfere with measurement and

reduce the sensor’s life expectancy. Consult PST-Aii for recommendations concerning the proper

selection and installation of components.

5.2 Connect your gas

To connect your gas:

GPR-x500 Oxygen Analyzer User Manual

1. See Figure 7 on page 15 for port designation and connect your Sample and Vent lines accordingly.

2. Regulate the sample pressure as described in below in "5.3 Calibration gases".

3. Connect a 1/8” or 1/4” vent line to the compression fitting to be used for venting the sample.

4. Connect a 1/8” or 1/4” sample line to the compression fitting to be used to bring sample gas to
the analyzer.

5. Set the Sample gas pressure between 5...30 psi (0.4...2.1 bar).

6. Select sample gas and allow it to flow through the analyzers and set the flow rate to 1...2 SCFH
(0.5...1 LPM).

Zero and span calibration gas ports are offered as part of the optional sample systems.

NOTE: If the analyzer is equipped with an optional H₂S scrubber, sample inlet pressure must not

exceed 30 psi (2.1 bar).

Do not place your finger over the vent (it pressurizes the sensor) to test the flow indicator when
gas is flowing to the sensor. Removing your finger (the restriction) generates a vacuum on the
sensor and may damage the sensor, voiding the sensor warranty.

5.3 Calibration gases

NOTE: It is recommended that you use a certified zero and span gases for calibration to ensure the

best measurement readings.

Cylinders of the appropriate certified zero and span gases should be made available for installation
and commissioning. Calibration gases will need to be set to the same input pressure and flow rate as
the sample gas to ensure calibration integrity.

16 ProcessSensing.com

GPR-x500 Oxygen Analyzer User Manual

5.4 Sample gas requirements

All gas analyzers utilizing electrochemical oxygen sensors respond to partial pressure changes in
oxygen. To ensure accurate measurement of the oxygen sample, gas must be presented to the
analyzer at a stable pressure and flow rate.

5.4.1 Inlet pressure

For the analyzers designed to measure oxygen in a flowing gas stream, the inlet sample pressure must
be regulated in the range 5...30 psi (0.4...2.1 bar).

5.4.2 Outlet pressure

The sample must be vented at a pressure less than the inlet pressure so that the sample gas can flow
through the sensor housing. Ideally, the sample should be vented to the atmosphere or into a flare at
atmospheric pressure.

NOTE: The sensor may be used at a slightly positive pressure (e.g., when sample is vented to a

common exhaust where the pressure might be higher than 1 atmosphere). However, the pressure at

the sensor must remain constant at all times including during the span calibration. This may be

accomplished by using a back-pressure regulator on the vent line of the analyzer.

If assistance is required to configure a measurement at a positive pressure, please contact PST-Aii
with full application details for a review.

A sudden change in pressure at the sensor may result in the sensor electrolyte leakage.

5.5 Prepare your zero/span gas

Avoid contamination of the zero/span gas cylinder when connecting the pressure regulator. Bleed the
air-filled regulator for a couple of minutes before closing the vent valve of the pressure regulator
(faster and more reliable method of purging the regulator than simply allowing the zero/span gas to
flow through the regulator and the span gas line).

The following components/tools are required to set up a zero/span gas cylinder:

a. Certified zero/span gas cylinder with an oxygen concentration, balance nitrogen, of

approximately 80 % of the full scale range above the intended measuring range.

b. A pressure regulator to enable reduction of gas pressure to between 5 and 30 psi (0.4...2.1 bar).

c. A flow meter (for use only if the analyzer is not equipped with one) to set the flow rate between

1 and 2 SCFH (0.5...1 LPM).

d. Suitable fittings and 1/8” diameter metal tubing to connect the regulator to the inlet of the

analyzer.

Ensure your zero/span gas cylinder valve is closed, then:

1. Install the regulator on the cylinder using good practice.

2. Open the regulator’s exit valve and partially open the pressure regulator’s control knob.

ProcessSensing.com 17

GPR-x500 Oxygen Analyzer User Manual

3. Slightly open the cylinder valve.

displayed up to 10% above the maximum range. Beyond this, an OVER RANGE warning will be
displayed.

6.3.3 Analyzer calibration

Figure 14. Default Range display

All electrochemical sensor-based analyzers require periodic calibration. The electrochemical sensor
signal will remain relatively constant throughout its useful life, however, some components in a gas
stream, e.g. sulfides, can adversely affect the sensor causing changes in sensitivity with time. As such,
regular calibration is recommended to ensure accuracy and ascertain the integrity of the sensor (e.g.
weekly intervals to a 3-month maximum).

Always use good calibration practices.

• Calibrate the analyzer at or close to the temperature and pressure of the sample gas.

• Use known reference gases or fresh air.

• Allow suitable stability time especially when making significant changes in measurement value (e.g.

20.9 % to 0.0 %). Use the table below for guidance.

Table 3: Example stability times

Condition example Typical stability time

<1 % to air (20.9 %) <3 minutes

Air (20.9 %) to 0.1% <30 seconds

Air (20.9 %) to 0.01% <2 minutes

Zero and span vs span calibration

Electrochemical oxygen sensors generate an electrical current that is linear or proportional to the
oxygen concentration in a sample gas. In the absence of oxygen the sensor exhibits an absolute zero,
i.e. the sensor does not generate a current output in the absence of oxygen. Given the properties of
linearity and an absolute zero, a single point calibration is possible.

Zero calibration is recommended only when the application demands optimum accuracy of better
than 5 % of the lowest range of the analyzer (e.g. for an analyzer configured for 0…25 % range, we
would recommend a zero calibration if measurements below 1.0 % O

Span calibration is required routinely for accurate measurements of oxygen.

NOTE: Zero calibration should always be carried out before a span calibration.

were required).

24 ProcessSensing.com

GPR-x500 Oxygen Analyzer User Manual

Zero calibration

The zero calibration adjustments are limited to 30 % of the most sensitive range. All analyzers are
QC-tested to confirm the zero calibration. Should you observe a zero calibration error more than 30
% of the lowest range, we recommend first:

• Check the sample system for any possible leaks

• Confirm the integrity of the zero gas

• Ensure the analyzer has been given enough time to stabilize on the zero gas

• Ensure CLIP = OFF, refer to " Clipping" on page 28 for information.

If adequate time is not allowed for the analyzer to establish the true baseline and a ZERO calibration
is performed, the analyzer will likely display a negative reading in the sample mode when exposed to
zero gas. If a negative reading is observed, we recommend repeating the ZERO calibration.

To perform a zero calibration:

1. Enter the Calibration menu and select Zero Calibrate.

The analyzer will switch to Zero Cal mode and display the live readings.

Figure 17. Zero calibration display

2. Once gas readings are stable you can Accept or Abort the calibration.
The calibration will Pass or Fail and the analyzer will return to normal operation at the configured
range.

During calibration ensure stability of readings, secure gas connections and supply of suitable
reference gas.

Span calibration

To perform a Span Calibration, enter the Calibration menu and select Span Calibration.

Figure 18. Span gas display

In the sub-menu, set the Span Gas value. If using certified cylinder gas, this can be found on the
certificate that was supplied with the cylinder:

1. Use to progress to the next digit or to move to the previous digit; use and to
edit the values.

NOTE: When a Span or Zero Cal starts, only "Abort" with is shown until the reading is stable,

then "Accept" with appears.

2. Now select the unit in use (% or ppm).

3. When you press , the analyzer will switch to the appropriate range and display the live

readings.

Once gas readings are stable you can Accept or Abort the calibration. The calibration will Pass or Fail
and the analyzer will return to normal operation at the configured range.

During calibration ensure stability of readings, secure gas connections and supply of suitable
reference gas.

NOTE: If using a ppm sensor we do not recommend exposure of the sensor to ambient air as it will

significantly degrade the sensor life.

7 Maintenance

The GPR-x500 will provide reliable and fault-free service with regular maintenance and calibration.

During periods without use the sensor should be purged with nitrogen or argon gas to preserve the
sensor life.

Do not attempt to make repairs to the analyzer. This will void the

warranty and may result in electrical shock, injury, or damage. All
servicing should be referred to qualified service personnel.

7.1 Sensor replacement

To maintain performance, the sensor in your GPR-x500 analyzer will require replacement. Sensor life
is application dependent.

GPR-x500 Oxygen Analyzer User Manual

When your sensor reaches the end of its serviceable life, calibration can no longer be performed and
the sensor must be replaced.

A regular program of calibration will mitigate against sudden sensor failure. It is advisable to establish
a program of preventative maintenance to ensure process downtime is kept to a minimum or avoided.

The protective plugs on your sensor should only be removed when your GPR-x500 is installed and
ready to begin gas measurement.

Refer to "5 Before connecting gas" on page 15 for the sensor installation procedure.

7.2 Routine cleaning

During sensor replacement, it is recommended that light cleaning of electrical contacts is carried out.

Never use chemical cleaning agents, solvents or high pressure water or steam to clean the

equipment. Do not submerge in water.

To perform routine cleaning:

1. Use a clean cloth that is damp with water to wipe away dust and dirt from the outside of the unit.

2. Dry the analyzer with a clean, dry cloth.

30 ProcessSensing.com

GPR-x500 Oxygen Analyzer User Manual

7.3 Routine inspection of sensor housing

The maximum interval between routine inspections should be determined with consideration of the
application and importance of the measurement.

The interval should be reassessed on a regular basis and can be extended and reduced as the process
control requires.

This can be carried out during sensor replacement. To perform routine inspection:

1. Ensure the gas entry and vent ports on the sensor housing are not obstructed.

2. Inspect the sensor housing seal and replace it if damage is visible.

7.4 Troubleshooting

• Ensure the correct calibration gas is used when performing a validation or calibration of your

analyzer. This will prevent unpredictable operation and incorrect readings.

• The calibration gas should be within range of your GPR-x500, typically 100 ppm for the 0...1 %

range analyzer, and 20.9 % for the 0...25 %. See the PST Factory calibration certificate supplied
with your module for specific calibration gas values.

• A faulty sensor or one that is incorrectly installed will display ‘FLT’ on your analyzer’s display.

• Do not expose the sensor to moisture in an un-powered state. If this happens, allow the sensor to

dry out, and if necessary, apply clean dry inert gas.
