Changing the Loop on a G4226x and G1367E Autosampler

Great video! Thanks for your work! Two small inputs if I may, better to use two wrenches when tightening the loop fitting to the needle, and it's good practice to rotate the loop cap together with the loop by one turn counterclockwise before feeding the loop into the cartridge.

I'm a consumables sales person, this is great to see someone performing these routine maintenance procedures.  Thank you!

I like the Sparks on the fingernails, is that standard for Field Service Engineers?
