    The cobbles are going to be very slippery tomorrow with all those riders crapping themselves

    Let's hope this one goes somewhere.

    Its about time :D

    'That leaves only the big protein-like substances such as growth hormones and EPO which cannot be detected by this method.'

    Nothing important then...

    But there are already tests for HGH and EPO and most scientists agree that doping has moved on to newer methods and undetectable substances.

    Interested in the commitment to retesting samples from 8 years ago onwards - haven't seen anything from ASO about that

    Really weird article - TOF-MS and GC-TOF is at least two decades old. I had my own research samples analysed this way a good 15 years ago.

    Apparently it was developed to test Dutch cows
  • Stagehopper, it's not the technique that's new, it's the way that they have implemented the chromatography prior to the mass spec. It's a modified protocol to ensure they catch as many metabolites as possible. The samples could then be rerun a different way to look for bigger things (HGH, epo etc.). You're right though that the techniques are old.

    Yeah, c'mon stagehopper, that's bleedin' obvious :wink:

    Be interested to see the paper itself. Think I was just assuming they (WADA) already had a wide-ranging GCMS or LCMS protocol to test for multiple metabolites like this. Think part of the problem is the article itself in physorg.com is dumbed down.

    I think they probably do but its not as fast or can only detect fewer metabolites in an equivalent run time.

    thanks for the link s_p. I assumed they were doing this already hence my confusion! Good to see it's now validated.

    Interesting read, I wonder what it will do to professional cycling.
