continuous peaks with waters 2487 detector
Posted: Wed Jan 19, 2011 5:14 am
Hello,
I am using the Waters 2487 detector and 717 sampler to analyse my compound since last 1 month.
I had given the machine to another student to use for 2 days and then restarted it today (using same column).
My problem is that even after equilibrating it for an hour I am seeing continuous peaks in the equlibration chromatogram. The peaks are one after the other. All of same size and same shape. The peaks are about 5-6 minutes broad!!!
I dont know what to do. I never had this problem in the ;last one month.
But another friend of mine used this machine 4 months back and encountered same problem (on a different column though) which means if there is an error its with the machine..
Please help.
