I need some TCEA help.  Our TCEA is pretty new but very sporadically used and I have yet to develop good practices.  Each time I come back to it I seem to have to start from scratch!  I need some advice on basics such as what backgrounds are acceptable, what precisions are acceptable, what tailing is normal, etc.  I need info on running organics for dD and d18O.  Does someone have lab methods / standard operating procedures that they can share?

I realize that is beyond a normal Isogeochem request so I am willing to pay for advice (maybe hire someone as a consultant?).

Thanks on this Friday afternoon (after a week of trying to figure it out and a pile of samples waiting!).
