GC Column Selection

[Jesse Robinson]

I currently use Resteks CLPesticide 1 & 2 for my drinking/waste water methods. Has anybody had any experience using the Phenomenex ZB-CLPesticide column pair? If so, what are your thoughts? Better or worse?

Thanks in advance!

In my experience most manufacturers columns are copies of each other though there are some specialty columns that might be a bit different. Phenomenex has been sending me coupons a lot lately. Otherwise perhaps you could get a demo or ask for a sample chromatogram.
