Main Features of the Calibration Procedures for GFF Version 2.12
The calibration procedure is split into four sections so as to improve the quality control of gas analysis.
Prior to calibrating the GFF gas panel
In this section the chromatograph cycle is checked for presence of C6. The time when C1 window opens and nC5 window closes are checked if they are in working range. The setting up of each gas component windows, auto tracking and base value are updated on the Setting screen of the GFF.
Chromatograph calibration for GFF
In this section the procedure of doing the Chromatograph calibration using the calibration kit is explained in details.
Total Gas multipoint calibration for DRY gas
Here the procedure of using the new multipoint calibration for Total Gas and setting up the Dry gas calibration table are explained. In this dry gas calibration method only Methane gas canister of different concentrations are used with the calibration kit.
Total Gas multipoint calibration for WET gas
In this section the procedure of using the Wet gas multipoint calibration table for Total Gas is explained. In this wet gas calibration method, Mixture gas canisters of different concentration are used with the calibration kit. In this table the physical value for each calibration point is the Methane Equivalent % of that gas canister is entered.
Items required in calibrating the GFF gas panel:
• Calibration kit. (700.BL.780)
• Mixture calibration gas canisters – (700.BV.527) 100ppm Mixture
(700.BV.526) 1000ppm Mixture
(700.BV.525) 1% Mixture
(700.BV.524) 5% Mixture
(700.BV.523) 10% Mixture

• Methane calibration gas canisters – (700.BV.522) 1% Methane
(700.BV.521) 10% Methane
(700.BZ.939) 30% Methane (optional)
(700.BV.520) 100% Methane
Note:
When you power up the GFF, let it run for few hours so as to have proper temperature stability inside the analysis module.
Always do the Chromatograph (CHR) calibration first and then do Total Hydrocarbon Gas (THG) calibration.
Check that the GFF air input is set at 3.5 bar pressure.
Check that the H2 is set to 0.5 bar pressure.
Things to be checked when you setup a GFF or replace the Analysis module and also when the flows are adjusted.
I. Prior to calibrating the GFF gas panel
1. Check for presence of C6 gas peaks (we do not measure C6 but can detect its peaks when flows are wrongly set). On the “Setting” screen change the cycle time from 42 seconds to 72 seconds. Then click OK.
2. Connect 10% gas mixture canister to the gas line port of the GFF analysis module using the calibration kit regulator and regulate the gas pressure to 1 bar.

5. Put back the cycle time to 42 seconds. Check the minimum time of C1 gas (open window); the open window of C1 should be between the range of 19 seconds to 22 seconds. If it is not in range then slowly adjust the Column Pressure regulator (clockwise rotation to increase pressure so as to allow the gases to come early in the cycle, counter clockwise for gases to come late).
For Auto tracking, time in seconds when C1 reach its maximum peak
Close nC5 window before 38 seconds
Minimum (open) C1 window between 19 to22seconds
6. Check the maximum time (close window) of nC5 gas, this maximum time should be before 38 seconds. If not in range than slowly adjust the Column Pressure regulator. Again check the C1 open window and nC5 close windows, they should both be in the working range. Note that the last 4 seconds of the chromatograph cycle time is required for the GFF computer to do internal processing of data.
7. If iC5 and nC5 gas canister concentration are similar but you observe that the respective curves are of different height then increase the Precut Column Flow by small amount. It is important that you should not allow C6 to be detected.
iC5 and nC5 gas peaks are of different height
8. Note down the minimum (open) / maximum (close) for C1, C2, C3, iC4, nC4, iC5 and nC5. Also check the C1 peak time for updating the Auto tracking time. Input all this information on the “Setting” screen table.
Minus two seconds from the Minimum (open) C1 window value to give you the Base value

9. Now flush / purge the GFF gas panel with compressor air, (use the extension tubing to connect compressor air to the calibration kit regulator) regulate this air pressure to 1 bar in Gas line 1 port of the analysis module. Also flush the Manual Injection port with air.
II. Chromatograph calibration for GFF
Since the Calibration port of the GFF analysis module cannot be used for the Chromatograph calibration, we have to use the Manual injection port located in the front of the analysis module. Follow the diagram shown below to line up the gas canister to the analysis module.
Manual injection port
Regulate the pressure regulator to set flow of 40cc/min on the Alltech flowmeter.
Connect the Calibration kit tubing to the Manual injection port along with the Alltech flowmeter in series as shown in the above diagram.
Now connect Air input to the Calibration kit, regulate the pressure regulator so as to have a set flow of 40 cc/min of air (less than 0.5 bar pressure) into the Manual injection port. Since the flow is set do not adjust this pressure regulator while doing the five points chromatograph calibration.
Connect the required gas canister to calibration kit, flush the kit with little gas and then connect it to the Manual injection port as shown in the diagram below.
It is a good practice to flush the calibration kit with calibration gas of the next injection so as to get better gas readings.

Each gas component (C1 – nC5) has a grid with black Theoretical curve and respective colour active curve with five injection points
Click Run
During the ‘Run’ mode, the display on the Gas Composition table starts with 100 ppm C1 as the first predefined gas mixture (injection #1). The gas from the canister flows through the CHR sample loop for @ 10 sec, then the commutation of 6 port valve takes place and analysis process begins for that gas sample. When that cycle completes, the ‘Validate’ box turns from grey colour text to black colour text. Click on ‘Validate’ to accept this calibration point for 100 ppm concentration, see that your calibration points for each of the components are close enough to the black theoretical point.
Note: Compare the gas readings displayed on the RTM* computer, these gas readings are base on the last active calibration and not your present calibration which is still not saved. Do not compare the reading for the first two to three cycles, the gas may be contaminated so ignore these cycles.
*use the latest RTM software version.
5. After validation if you find that this point is not good (as shown in the grid below) then you have to click on ‘Cancel’ before the end of the running cycle to go back to 100 ppm gas composition. Once the point is validated, the gas composition goes to the next predefined 1000 ppm gas mixture.
6. Connect the 1000 ppm gas mixture canister to the Calibration kit and flush the calibration kit tubing with gas. Connect the calibration kit to the calibration port and regulate the gas pressure to 1 bar on the pressure gauge.
7. Click on ‘Validate’ to accept this calibration point for 1000 ppm concentration. Follow the same procedure for 1%, 5%, 10% gas mixtures. The purpose of ‘Skip’ is to ignore a particular injection and go to the next injection point. You can skip if you do not have that particular gas mixture canister.
8. After you have validated all the five gas injections then you can click ‘Save’ then click ‘Yes’ to save your new calibration

3. For Total Gas you have two groups of calibration tables – Dry gas calibration table (using Methane gas canisters only) and Wet gas calibration table (using Mixture gas canisters only). Only one type of calibration table can be kept active. If you need Dry gas then highlight the dry Gas circle and click on ‘Select’ so as to make Dry Gas calibration active.
4. It is important to purge the GFF gas panel through the gas line #1 port of the Analysis module for few minutes. Observe the Raw μV signal (grey box at the bottom), if this signal is more or less steady (stable) then you click the first ‘UPDATE’ point. This will copy the raw signal value from the bottom to point #1 Raw box. For the Calib box type 0 ppm since air is used to get the Zero - no gas value. After updating the first point of Raw and Calib then click on ‘Validate’ to recognize the new point. Observe the Total Gas display window should show 0 ppm value, if Total Gas display is not showing 0 ppm then redo the raw μV signal value once again to have a proper Zero for the first point.

5. Connect 1% Methane gas canister to the Calibration kit. Connect the calibration kit to the Gas line #1 port of the analysis module and regulate the gas pressure to 1 bar on the pressure gauge.
6. Observe the Raw μV signal (grey box at the bottom), if this signal is more or less steady (stable) then you click the second ‘UPDATE’ point. This will copy the raw signal value from the bottom to point #2 Raw box. For the Calib box type 10000 ppm since the calibration gas canister was 1% Methane. Click on ‘Validate’ to recognize the second point. Observe the Total Gas display window should show @ 10000 ppm value, if not then redo the ‘Update’ for the same concentration of gas and again ‘Validate’.
7. Follow the same procedure for 10% and 100% Methane canisters.
IV. Total Gas multipoint calibration for GFF (Wet gas calibration)
1. Flush / purge the GFF gas panel with compressor air, (use the extension tubing to connect compressor air to the calibration kit regulator) regulate this air pressure to 1 bar in Gasoline #1 port of the analysis module.

5. Connect 1000 ppm Mixture gas canister to the Calibration kit. Connect the calibration kit to the Gasoline #1 port of the analysis module and regulate the gas pressure to 1 bar on the pressure gauge.
6. Observe the Raw μV signal (grey box at the bottom), if this signal is more or less steady (stable) then you click the second ‘UPDATE’ point. This will copy the raw signal value from the bottom to point #2 Raw box. Since 1000 ppm mixture gas canister will give 6750 ppm Methane Equivalent % (C1 + 2xC2 + 3xC3 + 4xiC4 + 4xnC4 + 5xiC5 + 5xnC5). In the Calib box you have to input Methane Equivalent value. Click on ‘Validate’ to recognize the second point. Observe the Total Gas display window should show @ 6750 ppm value, if not then redo the ‘Update’ for the same concentration of gas and again ‘Validate’.
Calculate the Methane Equivalent % base on the canister values for each component.
7. Follow the same procedure when calibrating the 1%, 5% and 10% Mixture gas canisters.
Mixture gas canister
Methane Equivalent %
1000 ppm C1 Mixture
6750 ppm
10000 ppm C1 Mixture
67500 ppm
50000 ppm C1 Mixture
200500 ppm
100000 ppm C1 Mixture
330000 ppm
Note: Since the 10% Mixture has the C6 components, it has to be included in the Methane equivalent %.
8. Remove the calibration kit from gasline #1 port of the analysis module and connect back the gasline #1 tubing coming from the pump module. Start both the pumps and flush out all the contaminated gas from the system. Now the GFF calibration is complete.
