This manual describes the steps involved in using the Agilent G3510-60820 Multi Mode Inlet Cleaning Kit to clean the Multi Mode Inlet (MMI) using solvent cotton swabs and dry abrasive swabs.
This guide provides a step-by-step procedure for cleaning the Multi Mode Inlet (MMI) on an Agilent gas chromatograph. The kit includes abrasive swabs, cotton swabs, and instructions on required external materials like acetone or isopropanol.
The process involves cooling the instrument, removing the liner and column, wiping the inlet bottom seal with a solvent-moistened cotton swab, and scrubbing the bottom of the inlet with an abrasive swab. Finally, the inlet is rinsed with clean solvent to remove residue before drying and reassembly.
You will need at least 25 mL of acetone, isopropanol, or hexane depending on the sample matrix.
Cleaning frequency ranges from weekly to monthly depending on sample cleanliness; an initial schedule of every two weeks for dirty samples and every two months for clean samples is appropriate.
Yes, light brown coloration due to oxidation is normal and will not affect inlet performance.
