Our Agilent 6890N GC is getting a lot more use these days, so I'd like to have the instrument print out the barcodes for each ASV in a sequence. The instrument does have a working barcode reader, but I can only get the barcode to appear if it is "read" and input into the sequence by the user before the run. How can I make it read and print out the barcode automatically in the header as part of a run? Our current header macro prints out a space for "barcode" but it is blank. I"m not very versed in macro-speak, but I do have someone who can help me out if you can point me in the right direction. This instrument is running MSD Chemstation E.01.00.237.
