We have a new CE EA 1110 CHN and would like to incorporate a certified sediment standard into our calibrations.  I have been unable to get a hold of NIST 2704 Buffalo River Sediment as it is back ordered at NIST until at least May.  Does anyone know of any other certified sediment standard for measuring % carbon and nitrogen or have enough of NIST 2704 to be able to spare me some until I can replace it when my backorder arrives?
 Thanks, Margaret
