Frequently Asked Questions
Answers to common questions about stable isotope analysis, sample preparation, turnaround time, and reporting.
General Questions
What types of samples can you analyse?
We analyse water, soils, sediments, plants, animal tissues, food products, geological materials, and many other organic and inorganic samples.
Which isotopes do you measure?
We routinely measure δ13C, δ15N, δ34S.
Samples & Preparation
Do you provide sample preparation?
Yes. Clients can submit pre-weighed samples or utilise our complete sample preparation service.
How should I prepare samples for IRMS analysis?
If you choose to pre-prepare samples, they should be accurately weighed into high-purity tin capsules (available from Elemtex) using a microbalance with a precision of at least six decimal places.
Do you provide sample preparation?
Yes — we offer grinding, drying, weighing, encapsulation, and water extraction depending on sample type.
Turnaround, Pricing & Reporting
What is your turnaround time?
Turnaround times depend on sample type and workload. Express service may be available depending on workload.
How do I request a quote?
You can email us directly or use the contact form. Provide sample type, quantity, and required isotopes.
What does the report include?
Results include δ‑values, raw data, QA/QC metrics, standards used, and method notes.
