Chromatography Forum

I am thinking of buying a Corona Charged Aerosol Detector (Corona CAD) for ours HPLC system. It is possible to work with gradient elution with a Waters system or agilent system connect to a corona. Thanks

If you're asking about connection in terms of using a data system with the CAD, then yes, it should be possible as pretty much all data systems can accomodate a detector that, if nothing digital fits available drivers, will take a 1V analog output via A/D converter.
CADs include a 1V analog output (as do nearly all detectors). The A/D will be specified by your chromatography system vendor...

Yes-CAD can be run using Waters and Agilent. Waters uses an eSatin module.

Yes the Empower driver can be bought from Thermo. Let see the next dokument:http://www.dionex.com/en-us/webdocs/88847-Man-Instrument-Integration-Empower-ver1-10b-Install-Mar2011.pdf

Hi Dalia,

Quickly following on from some of the comments above... What CDS are your using?

We are using Empower2 FR5 build 2154 in a Citrix enterprise environment. Cannot install the Corona CAD ICS on any LAC/e or Dev Citrix server. any thoughts. No response from Thermo

Absent the driver & license, you can always use an eSAT/IN.

Citrix won't be a problem as you are connecting the CAD with an acquisition client or LAC/e.
If there aren't drivers available for Emp 2 FR 5, then you will have to switch to an eSAT/IN connection with the CAD.

The Empower 2 Integration driver is available, which includes drivers for the CAD:

Contact your local sales or service representative and they will be able to advise how to get hold it.

Thanks

Thanks Anthony,
Thermo Fisher has been incredibly non-helpful (Northeast). We have moved forward with e-SATIN connection only. Once we were responded to, we were informed, "This driver has been replaced by our product “DII” (Dionex Instrument Integration). You should install this. This probably means that you need to contact your Thermo Fisher Services representative again to get the DII installed"

The driver they were referring to was the one that the service tech said had to be installed is, "Dionex/ESA CAD Detector and the associated support ICS (Version 2.1) that supports module control by Empower 2."

Anyways, no one has sent us DII.

My guess is that the DII is not free.
Either Thermo/Fisher(/Diones) has to pay a royalty to Waters to cover license fees, or you would need a separate license from Waters installed to get the DII to run.

Either way, you would owe someone some $ that would (eventually) go to Waters for the privilege of having instrument control of a non-Waters instrument on a Waters CDS.

The only downsides to using an eSATIN are 1) you have to manually shut it off at the end of a run - unless you rig a switch and event to do that for you and 2) the eSATIN A/D conversion may not be quite as clean and quiet as sending a digital signal out from the detector might be.

Hello,

As DR pointed out, DII is not free- there is a nominal charge (although in most places, it's less than the price of dinner for two ). The installation guide is quite detailed and you could probably install it without a service visit. Order part number 5960.0189.

Best regards,
John

If you consider dinner for two being at MacDonalds, it's probably not far off!

Note that version 1.12 of DII has just been released this week. This is based on Chromeleon 6.8 SR13 and offers extended support for existing instruments as well as new drivers.

Thanks
