Stable Isotope Facility

University of Wyoming

All water samples submitted for analysis must be free of particulates. If particulates are found in water they will be filtered and charged a $2.50 filter charge per sample.
Samples must be shipped and submitted in air tight vials with no head space. To avoid leakage during transport you should wrap parafilm around the lid of the vial.
For small sample amounts use appropriate small sized conical bottom vials.
If you ship extracted water samples in glass tubes and need part of your samples to be saved please provide us with appropriate vials.
If water has a salinity above 500mg/L the water will need to be run with code 023 on IRMS.

Required sample size:
100 to 500 microlitres

The SIF tray loading template MUST be used to submit samples. Templates were updated as of August 1 2019.
Fill out only the sample Id column in the tray loading template.
The sample IDs should be unique. Do not repeat sample ID names. The names should be less than 20 characters long and cannot include special characters (e.g. ! @ # $ % ^ & * ( ) . / \ +.";') on the sample list. Only hyphens ( - ) are acceptable.
If there are any modifications to the template or the template is not used, the samples will be returned to you and will not be placed in the queue.
Once template is filled out properly and saved follow the link below to be taken to the order form.
