Title: Eichrom's
Users' Group Workshop at BAER 2000, A Discussion of Matrix and Speed
Chairperson: Lawrence
E. Jassin, Eichrom Technologies, Inc.
Time and Date: 3:30-5:00 P.M., November 13, 2000
Eichrom Technologies is
a manufacturer of a wide variety of separation technologies, including
extraction chromatographic materials.
These materials are widely used for the separation of actinides, rare
earth elements, radium, technetium, strontium, nickel, iron and tritium from
environmental, bioassay, process and waste samples. This year’s workshop will showcase analytical methods involving
urine, air filters and very large soil samples. Two of the talks will also emphasize the benefits of vacuum
assisted flow to reduce the separation time required for analysis. Eichrom is now supplying 24 station vacuum
box systems along with prepackaged resin cartridges.
Gerald Levi of
Westinghouse Savannah River will present details of his Bioassay lab's use of
the new Sr Resin cartridge for Sr analysis in urine. Recent improvements in Sr yield and timesaving using vacuum
assisted flow will be discussed.
Mitch Abbate of
Barringer Laboratories will present recent work analyzing Tc-99 in air filters
using TEVA Resin. He will discuss how
he investigated a high bias to the Tc-99 activity determined via LSC and how he
now eliminates the cause through a modification to the Eichrom Tc-99 method.
Bill Burnett of Florida
State University (predicting a number one ranking for his Seminoles football
team by the time of his talk) will update us on his group's research into
efficient preconcentration and separation of actinide elements from soil and
sediment samples. This research
utilizes Eichrom's DiphonixÒ Resin to pre-concentrate actinides in soil
samples (up to 50 grams) prior to use of Eichrom's TRU, UTEVA and TEVA Resins
to isolate the individual actinides.
Mike Schultz of Perkin
Elmer Instruments will present recent work on a sequential actinide method in
urine.
At the time of the
writing of this abstract we are still putting our final agenda together. The above is a glimpse of the real-world
radiochemistry discussion planned for our workshop. As always, attendees to our workshop will receive a binder
containing the overheads used during the presentations for future
reference. We also will upload these
presentations to our web site, http://www.eichrom.com/.
