I would like to make the purchase of a new GPC software.
I currently use software "Cirrus" of Polymer Laboratories .
does anyone have an opinion on GPC software used by agilent and also by EZchrom Elite?

I would say that for peak positioning calibration, the software is okay. Especially if you work in a lab where also HPLC is used, than just one software platform would be needed.

Cirrus is dedicated to GPC and has more options for calculations
.

thanks,
I suppose that the Agilent soft cannot make multi detection , isn't it?

No, like I told before it’s not very sophisticated. I personally would stick to Cirrus.

I am familiar with the GPC Addon for the ChemStation. It does perform all the necessary calculations, including multi-peak evaluation. It has full capability for calibration.

However, like most software programs, it is not easy to learn.

If you are interested in light scattering and viscometry then I would look at Viscotek and Wyatt as well.

Brookhaven Instruments (my employer) offers ParSEC. ParSEC supports light scattering and viscometry in addition to standard GPC.

It is also easy to learn.

I know Wyatt and Viscotek but I think that their possibilities exceed current needs and staff
but I don't know ParSEC and I'll find out
thank you everyone

I am familiar with the GPC Addon for the ChemStation. It does perform all the necessary calculations, including multi-peak evaluation. It has full capability for calibration.

How does one learn to use the Cirrus GPC Add-on for Chemstation? I thoroughly read the online "Help," but it does not make sense. I am very familiar with the Perkin Elmer GPC software and am new to the Agilent Cirrus GPC Add-on.

I know this is quite an old topic, but: Is there any "cheap" software to analyze GPC data?

I have an old system waters 600 + RI 410 + PDA996, and the millenium 32 computer we had with GPC add on died. Now I'm measuring in a Empower without GPC add on, exporting RI and PDA traces as .arw (ascii files) and manually calibrating and processing in origin + excel.
Just need a software that just does this for "relatively" cheap, and hopefully not suscription based unless really cheap.

Are there softwares like that available? Which would be the cost for a single user/single computer? (most vendors have "quote/inquiry" and the GPC function is an add on on a quite feature rich (aka expensive) base software)

Are there any options out there or am i better off trying to revive the old millenium 32 computer / keep processing by hand?

The use is academic only.

millenium is a Antique.where are u，may i can resolve the problem.
