Compound Specific ¹³C & ¹⁵N analysis of Amino Acids by GC-IRMS Pricing

Price is inclusive of duplicate analysis; triplicate measurements will be made, at no extra charge, if duplicate measurements fall outside typical measurement error. Researchers may request all measurements to be made in triplicate at additional cost. Samples with matrices that require additional preparation requirements (e.g. cation-exchange chromatography) will incur additional costs. Please contact us for details.

All projects are accepted on a case-by-case basis and must be scheduled with the SIF prior to sample submission.  Samples arriving at the SIF without prior approval will be returned at the shipper's expense.

As of December 1, 2022, the SIF no longer accepts individual CSIA of amino acids projects totaling greater than 100 samples. By nature, this is not a high-throughput analysis and this restriction has been put in place to allow for equitable service to all SIF clients. If you are planning a project > 100 samples, please contact us to discuss how those projects might be accommodated. We appreciate your understanding.

Shipping
Dry, homogenized samples should be shipped dry in 0.5-1 dram glass vials.  

First, complete and submit the online Analysis Order Form and Sample List for your samples. Shipment may proceed once you receive email confirmation from SIF staff.   Be sure to also include a printed copy with your samples. The SIF uses this form to track your samples and to contact you regarding receipt of samples, data, and invoicing. For mixed analysis requests, we require the completion of a separate form for each type of analysis.
