Chromeleon data systhem

[danielbor]

Hello forum members


Can somebody recommend which option is the preferred architecture for Chromelone software?

1.To use local PC`s and to first assess the raw data to produce final reports and to transfer them to server?

2.To transfer the raw data directely to the server and than to perform chromatographic reports.


Is there is a possibility that working with about 20 instruments could overloud the network capabilities while transferring directly the raw data to the server (option 2)?

Thank you in advance

in option 1 do you mean that everything would be done in a stand alone station and then the results would be transferd as PDF forms to a location on your server?

[danielbor]

Thnk you unmgvar

Yes, in order not to overload the data trasfer that might cased a difficalties regarding the net.

it seems that your organisation has not yet trully decided if to make the switch to a C/S. why are you consedering to do it?

have you looked at the differences between staying at the stand alone level in contrast to having a C/S control over the instrumentation and data?
trust me once you go C/S your analitical users will hate working with any left over stand alone system in your lab.

as for the fear of network capabilities, there are far bigger installations out there using far more then 20 instruments. if you run into network overload it will only due to the fact that you have a very incompetant IT team that takes care of things in your business and that the infrastructure that the C/S will use was badly set up by that team to beging with.
if you are already know that you are having overload problems with your existing structure then fix them otherwise you are right you will only be adding a new factor that will increase the chances that things will go wrong, but it won't be the softwares fault.

what does your local Rep says?
does he knows of your questions?
do the Dionex people know?

ultimately on all counts, option 2 is by far the better one

Thank you unmgvar

We are now in a process of purchasing C/S system and all these questions are come up. As a pharmaceutical company we should work in GMP environment that comply CFR 21, 11. C/S seems to us an suitable solution.


Do you have an experience me how many HPLC for computer is recommended for pharmaceutical QC and R&D company?
Thanks

Dear Danielbor,

with Chromeleon you have more than thse options available.

1. You can store the raw data locally and transfer them to the Central Server manually or by an automatic process, free selectable conditions.
2. Or you store the raw data directly at the central server, with enhanced security features, like Network Failure Protection, in case of NEtwork errors, the data are kept locally in a secure environment and stored at the central server, whenever the network is back
3. From our exeprience there's no overload with even more than 20 instruments. There are installations with more than 500 instruments on the same server.
For more than 50 systems, it would be a good idea to dedicate an own network but not really necessary

option 2 suggested by TakeControl is the "formal way" that Chromeloen works for transfering the data to the server. as he mentionned this proccedure is protected from corruption via the NFP module. also the software can be prompted to be aware of scheduled network disconnection for maintenance purposes. for example updates of the operating system or of anti-virus software, things like that.

as for the amount of HPLC that can be connected to one IPC at a time, this as i said to you the first time you posted, very dependant upon the type of HPLC being connected.

for example Agilent's lan connection is generally bad so you can't safely connect more then 2 on the same PC and Dionex won't be responsible if you decide to connect more instruements then what they recommend.

anyway you will save on the amount of PC that you use. also this is not the correct way to look at the benefit given by a C/S

the major benefit for me is the data accessibility and flow. this will save your user about 50-70% time, just by saving them the need to walk to the instrument. this time saved is a huge increament in productivity.

also the level of automation provided by chromeleon regarding reporting is so high that again your user can save more then 50% of the time that they use to waste.

have you contacted other customers.
i know that novartis has several site using chromeleon over europe.
also a site of sanofi aventis in frankfurt is a good choice.

Tanks for all for your detailed replies

I believe that the next generations of software will be based on web.

Does anybody know about this approach?


Thank
