we've been using the Biacore Q system for some years now to determine the concentration of certain vitamins in our products. But unfortunately GE healthcare, the firm that produces the Biacore Q system, has decided to stop with the Biacore systems. That means that they wont ship anymore new vitamin assay kits in a few years and no more support for our Biacore Q systems.
Can anyone tell me if there are other suppliers, with SPR techniques, that can deliver both the equipment and the kits to do the concentration analysis?
SPR instrumentation from SensiQ company could help.
I have got Pioneer series instrument which I primarily use for studying interactions of small molecules to proteins, but I am sure there assays could be extended to other applications.
or I can pass your details to them if you prefer...
