Our laboratory is equipped with 5 modern continuous flow - isotope ratio mass spectrometers.
The above services are routinely undertaken and available immediately.
Use our quote form to obtain a price for isotope analysis of your standards.
Please contact us if the analyses you require are not listed.

The calibration of the stable isotopes in any sample supplied to us involves the following steps:

(1) Booking in and inspection of the sample upon receipt.
(2) Preparation of the sample for analysis.
(3) Five replicate measurements of your sample against traceable standards.
(4) Repeat step (3) on two further days.
(5) Collation and interpretation of all sample and QC data into a laboratory report.
(6) Advice on how best to store your sample for use as a working standard.
(7) Issue of a certificate of analysis to you and return of any unused sample material.
