Maxum II Initial Startup Procedures, Continued

 At the end of the cycle, import the chromatogram:

File > Data > Import.

Compare the chromatogram to the factory chromatogram provided with the documentation. Pay

particular attention to the peak retention times, valve timing and separation. Adjust valve times

as necessary. If the retention times do not closely match factory documentation, first make sure

the column oven has been equilibrated at operating temperature for at least two hours. If not,

allow the oven time to equilibrate.

 If the oven has been equilibrated for two hours and the peak retention times are significantly

slower than shown in the factory data, cool down the oven and leak check. After finding and

eliminating the leak, repeat the previous two steps until there is reasonable agreement with the

factory retention times.

 If the peak retention times are significantly faster than the factory data, measure the flows and

adjust the EPC setpoints as necessary.

 Repeat the previous four steps until the chromatograms obtained are reasonably close to the

factory chromatograms.

Calibrate the Maxum II

 Save the last acquired chromatogram for calibration. Save the method.

Calibrate from the menu:

Analysis > Single Level Calibration,

check the Calibrate box at the top of the dialog box

and check the box for Clear All calibration.

Press the Start button to complete the calibration.

 Save the method, then export it to the Maxum II; do not change the method name when

exporting.

 Continue to run the analyzer. At the end of the cycle, import the chromatogram and verify that the

analyzer is properly calibrated.

 From the System Manager, through the menu, back up the Maxum II database:

System > Unit Backup/Restore,

select the Maxum II by it’s IP address in the dialog box,

type the desired name of the backup file to be created

or browse to select an existing file (press the arrow in the dialog box to browse), browse to

select the desired folder and subfolder,

and press the Backup The Analyzer button in the lower left of the dialog box.

Note: The Advanced button will allow selection or de-selection of the Save to Flash function

prior to the backup. It is recommended to always use the default Save to Flash option. For

details, see Workstation, Advance System Manager help file.

Run the Maxum II on Process Fluid

 From the MMI, select the desired process stream and leave the Maxum II in Run.
