We tried this in our lab very briefly and did not get any improvement in

In our lab we routinely do quantitation using ECL and Hyperfilm.  One
should be aware of the limitations of the film and use an internal
standard for each run.

Yes, you can get from Amersham, but I don't think it is wroth your money. 

The above reply leaves out much detail that I care not to type. If you
wish to discus this any more E-mail me directly.
