cost of analysis

 combined carbon & nitrogen

$15.00/sample. Includes;

  • 𝛿13C and 𝛿15N

  • %C and %N

  • Relative Abundance of Carbon to Nitrogen (C:N)


$20.00/sample. Solid samples only. Includes;

  • 𝛿D and 𝛿18O

  • %H


glass fiber filters


  • It is recommended that an electric pump be used to filter water in order to ensure an adequate amount of material is collected. 

  • Please send several blank filters (2 for every 30).

  • There is no guarantee for data generated from glass fiber filter papers.

weighing samples

  • $6.00/sample for homogeneous dry ground tissue.

  • $8.00/sample for any samples that require sub-sampling (e.g. feathers, fur, fins, and scales).

  • Please add an additional $5.00/sample if grinding is needed.

    • NOTE: samples need to be ground into a homogeneous sample in order for us to run them.

drying samples

  • $1.00/sample

  • NOTE: It is the responsibility of the client to ensure that 'fresh' samples submitted for drying are contained in oven-safe vials. Furthermore, if fresh samples are sent in vials taller than 8cm, the sample will be transferred into glass scintillation vials at the client's expense.


  • $50.00/hour

    • This includes any treatment of samples prior to oven-drying (e.g. decanting ethanol and rinsing samples with distilled water, moving frozen samples into glass scintillation vials, dissections, etc.)

  • $10.00/sample for lipid extractions and/or acid treatment

Additional charges may be applied to samples not meeting required submission standards.

Discount pricing may be applied to bulk orders (5% for 200+ samples, 10% for 500+ samples and 15% for 2000+samples). 

Carbon and nitrogen isotopic ratios are simultaneously derived during sample analysis. Hence, the price per sample includes both isotopes (unless the C:N dictates separate analysis).


All stable isotope analyses requiring a legal contract will be subject to a 15% overhead charge.  This overhead will cover the additional administrative costs as per the partnership agreement between the University of New Brunswick (UNB) and the Stable Isotope in Nature Laboratory (SINLAB).
