Honeywell Burdick & Jackson® Sample Cleanup Products
By Honeywell Burdick & JacksonCleanup of an extracted sample is done through the dispersive-solid phase extraction process, and requires a formulation of pre-measured salts and sorbents packaged in a centrifuge tube. If the dispersive SPE cleanup is not sufficient for total sample cleanup, alternative columns containing a top layer of graphitized carbon black (GCB) and a bottom layer of primary secondary amine (PSA), separated by a PTFE frit, may be used.
