Pricing Guide
We don't like charging, but we have to. Really.

Always contact us before sending samples! Prices can change without notice. Prices do not include supplies, such as. tin capsules. Samples are run as time permits, turn-around times will vary. No shirt, no shoes, no service! (Disclaimers had to go somewhere...)

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 1020°C, copper reduction column at 650°C, and a magnesium perchlorate column to remove water) connected to the Thermo xxxx (e.g. Delta XP) via their xxxx (Conflo III) peripheral. Gases (He, O₂ and CO₂) were supplied by Airgas, with the CO₂ and N₂ standardized against 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.

Prices listed are for Academic "rack-and-run" style samples. Prices vary for other situations.

Notes:
1. Taxes for commercial work are not included in prices.
2. Estimated final cost per sample: this takes into account the cost of runnign replicates. Of course, this will vary depending on many factors, such as the need for extra standards. The TC/EA usually requires at least triplicate runs (if not more).
3. Prices for methods in development are not final and subject to change.

Disclaimer: Listed prices are estimates only. Actual costs may be higher or lower depending on many factors, including method development required, number of standards needed (for new methods or more exact results), sample preparation, necessity of "clean-up" runs, etc. Contact the lab for more information.
