Janet,

Isotech Laboratories can provide all of the analyses that you requested and
has had a substantial amount of experience with the solid waste industry.
We do stable carbon, hydrogen, and oxygen isotope analyses as well as
carbon-14 and tritium analysis of both gases and waters.  We just recently
went on line with an electrolytic enrichment system for doing low-level
tritium analysis of groundwaters.  I believe we are the only commercial
(non-government or university) laboratory in  North America offering this
service. We can also provide carbon-14 analysis of gases and DIC by either
beta counting or, when sample size is limiting, by accelerator mass
spectrometry (AMS).

We offer reliable turn-around times and rush service when necessary.  We
maintain a supply of all different types of sampling containers ranging from
gas cylinders to water containers and can make these available on short
notice, along with instruction sheets for collection and shipment of samples.

I will mail you complete information on our services, and information on our
QA/QC program. .  I would also be happy to provide you with names of
references you could contact concerning the reliability of our data and the
quality of our service.
