ASTM Noise Test
Posted: Tue Mar 13, 2012 11:21 pm
I just changed out my deuterium lamp on an Agilent 1100 series HPLC. Right before I changed this lamp, I did the DAD self-test, and discovered failing results from the 20 minutes ASTM noise test. Now, I went to do the DAD self-test again, but now once it runs through the self-test (which are all passing), it just says the self test is finished without running the very last test, the 20 min. ASTM noise test. What am I missing? I do have it checked in the dialog box as well, so I don't understand why it is doing this.
