Subject: The GeoFastFID (version 2.12) calibration procedure is somewhat similar to the |
Reserval II procedure. The Calibration port of the GFF gas panel cannot be used to |
calibrate the chromatograph five points calibration instead the manual injection port is |
used. A new quick look procedure to do the Chromatograph and Total Gas |
calibrations is documented here. |
|
Operating System: The GFF version 2.12 can operate under Windows 2000 (611.AA.760) or Windows |
XP (700.BV.519) operating system environment. |
|
Port Setting: The communication ports and speed settings are very important both on the GFF |
computer and also on the RTM computer. |

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. |
|
妈 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. |
妈 Chromatograph calibration for GFF |
In this section the procedure of doing the Chromatograph calibration using the calibration kit is |
explained in details. |
妈 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. |
妈 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.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. |

Display the GFF screen on Chromatograph cycle on log scal3. e and check if C6 present. Do this process |
for 3 complete cycles to confirm there is no presence of C6. |
|
|
|
|
If C6 gas peaks are not present (as above), put back the cycle time to 42 seconds and go to step #5. |
|
|
|
If the C6 gas peaks are present (as above) than redo the CHR Column Precut Flow again (in this case |
the Precut flow has to be reduced |
4. |
). After setting the precut flow, again check the chromatograph cycle |
for presence of C6 gas peaks. |

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). |

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 |

|
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. |

|
ꓸ Connect the Calibration kit tubing to the Manual injection port along with the Alltech flowmeter in series as |
shown in the above diagram. |
ꓸ 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. |
ꓸ 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 |

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. |
