STANDARD OPERATING PROCEDURE (SOP) FOR OPERATION OF FLASH CHROMATOGRAPH

Standard Operating Procedure (SOP) for Operation of Flash Chromatograph

1. Objective: 

To establish a detailed and efficient procedure for the operation of the Flash chromatograph.

2. Responsibility:

 The operation and maintenance of the Flash chromatograph are the responsibilities of the Technical Assistant, Technical Manager, Quality Manager, and all individuals using the instrument.

3. Instrument Details Make: Buchi
Model: X2

4. Procedure:

4.1. Logging EntryRecord the in and out time in the instrument logbook.

4.2. Switch On

4.3 Electrical Check: Verify the electrical plug points and turn on the switch.

4.4 Solvent Level: Check the solvent level to ensure it is sufficient for the entire run.

4.5 Priming: Start the auto prime to clean the lines.
Perform a manual prime if using a different solvent than the previous user.
Ensure the lines are placed in the same solvent reservoir as programmed (preferably ethyl acetate and hexane).

4.6 Preparation: Place all racks in the fraction collector.
Download existing methods or prepare a new method according to your TLC.
Set the detection wavelength based on the UV profile of your compounds (up to two wavelengths).
Specify the amount of solvent to be collected in tubes.
Check for any solvent leakage.
Select the column based on your sample quantity (e.g., a 4 g column for a maximum of 400 mg of sample).
Specify the type of sample loading (solid or liquid).
For solid loading, adsorb your sample on the stationary phase.
Ensure the surrounding area is clutter-free.

4.7. Switch Off Post-Run: Allow the automated flush and purge to complete after the run.
Save your run or transfer its PDF version to a USB drive.
Remove the cartridges and columns.
Turn off the instrument and the main switch.
Sign off in the instrument logbook.

5. Unattended Operations 

The instrument can be run unattended for short periods (~30 minutes).
Overnight operations are not permitted.

6. CleaningClean the sample preparation area and the vicinity of the instrument before logging off.

7. Precautions for Use Ensure the column is free from contamination by washing with the suitable solvents.
Keep the solvent reservoirs covered with proper lids.
Ensure racks are emptied after the run is complete.
