column selector

[mardexis]

I am looking for anyone with experience running column selectors with Agilent 1100's. The product from Chiralizer looks good but I want to get feedback from anyone that might have used it or others.

Also...the sales guy told me that EVERYBODY has one but would not give me a specific person to ask. I would like to find someone in the Bay that has one setup that I might be able to take a look at.

Many Thanks,
Marc

We run two 1100s with column selectors. Both work well in our QC dept, although I am not sure if they were worth the money. Our QC dept is manned 24/7 so there is no real need for programmed column switching. You are welcolm to come and see them....We are in the bay area, unfortunately it is in the bay area of the River Forth in Scotland!! (lol)

mardexis,

I distribute column selectors in the Bay Area and have never run into a Chiralizer selector. Please feel free to contact me directly and I can get you in touch with some individuals that have used 6 port column selectors.

We provide valve solutions for multidimensional HPLC and on-line sample preparation. They are easy to install and to use.

I am in a method development lab and we have about 10 different column selectors (from Alltech, Rheodyne, Supeco, Chiralizer, etc.). I like the Spiderling from Chiralizer the best. it has column temperature control, and can do up to 9 columns at a time. WE have mostly Agilent HPLCs, this works well with Agilent instruments (comes with pre-programmed ChemStation methods). We just ordered one more Spiderling Deluxe last week. It is the most expensive one among those we have.

I am not in the bay area.

Dear Mardexis,

My experience with column selectors started long ago (1982). I put together a few from Rheodyne valves and I even added solvent selector valves. The idea was that QC labs will have fewer problems with columns and methods since they will not have so much column and solvent manipulations.

The truth was that after a few months all the selector I built where discarded or disassembled, people just did not liked them. The perceived advantages were not worth the money or the change to a slightly different routine.

I remember also, that PErkin Elmer designed a whole instrument around this principle, and it was a failure, they never sold enough of them and the idea was dumped after a few years.

My recomendation is to think carefuly about getting into these systems, do you really want it, is it useful to you. I can not tell for sure, but I have the impression they are not widely used.
