Sample requirements

What to provide before work begins

Provide representative, clearly labelled samples and identify the decision, feature or comparison that matters.

Suitable sampleSubmission requirementPlanning note
Solid / componentProvide a clean, stable and clearly labelled specimen with the target face or region identified.Confirm dimensions, cutting permission and whether the original geometry must be preserved.

Objective: state the decision, comparison or acceptance criterion the work must support.

Handling and access: declare hazards, instability, confidentiality, file constraints or special logistics before dispatch or transfer.

Questions and answers

Common planning decisions

Short answers to issues that can change preparation, scope, timing or interpretation.

What should I send for Thermoluminescence / Optically Stimulated Luminescence Spectroscopy?

Provide solid / component as applicable. Exact quantity, dimensions and preparation are confirmed during technical review.

Which analysis option should I choose?

Choose the mode around the decision you need to make. For glow or stimulation curve, start with thermoluminescence; add continuous-wave or pulsed OSL when comparison or quantification is required.

How long will the test take?

Typical turnaround is 6 working days after sample acceptance and method confirmation.

What can limit the result?

Signal history can be reset by light or heat. Dose conversion depends on calibration, fading, sensitivity change, and mineral composition.
