* when submitted in bulk (n > 500), costs are reduced to $7.50 per sample. 

† actual cost depends on sample preparation. For example, $3 is added to the sample cost for each of the following procedures carried out by CPSIL prior to isotope analysis: (a) grinding, (b) weighing, (c) acid-washing. Other procedures are more expensive (e.g., lipid extractions, inorganic nitrogen diffusions, etc.).

Analyses are usually invoiced for payment following completion of the work.  If necessary, payment can be made in advance for credit.  Our Tax Identification Number is 86-6004791.
