*Subsampling is an incidental fee. Samples exceeding our maximum acceptable concentration of 50,000 ppm CO2 will require subsampling. We ask that you send your samples in appropriate vials (i.e. 12 mL Exetainers). The submission of samples in alternative containers must be discussed and approved ahead of sample collection/shipment, otherwise your order may be declined and returned plus shipping cost.

Turnaround time estimates are valid for projects of 200 samples or fewer. 


Contact us for estimates regarding larger projects or to discuss your gas vials.
