If
you use
our facility, please acknowledge us. For example, Stable
isotope
measurements were done at the Earth System Center for Stable Isotopic
Studies (ESCSIS), a Yale Institute for Biospheric Studies (YIBS)
research center. For descriptions of work: We used xxxx
(e.g. Costech ESC4010 with a standard N/C/H reactor at 1020oC,
copper
reduction column at 650oC,
and a magnesium perchlorate
column to
remove water) connected to the ThermoFinnigan xxxx (e.g. DeltaXP) via
their xxxx (Conflo III)
peripheral. Gases, He, O2
and
CO2
were
supplied by Airgas, with the CO2
and N2
standardized against a
reference CO2
and N2
tanks respectively from
Oztech Trading
Corporation. Stable isotope values were checked
against our
lab reference material, xxxx.
Percent yields were determined
from
the mass spec by comparing peak areas of the main isotopic signal
against xxxx (e.g.
acetanilide supplied by Costech). This
information is also found in ESCSIS-equip.doc,
along with a brief description of equipment.
Discounts are
available for running your own
samples, or if
you are a member of the Yale community, in a participating department
or member
of the facility. Please contact me for your price
list. For
commercial work, add approximately $15/run. This pricing
guide is
for outside academic users and can also be found in ESCSIS-pacad.doc.
Remember,
collaborations are done with members of the ESCSIS board, not with the
facility itself. Also, we reserve the right not to take on
any
given project.

Est.
cost per sample: takes into account
cost for
running replicates. This will vary depending on a
number of
items,
e.g. extra standards or running all samples extra times will increase
the per
sample cost. TC/EA usually requires at least triplicate,
maybe
quadruplicate, runs.
For
natural abundance samples, heavily enriched samples may require "clean
up" runs.
N.B. If you are doing
something
new in your lab, you will be running more standards as well as each
sample
multiple times. The same will be true if you are looking for
very
exacting numbers. That will increase the cost per
sample.
