What this service offers

The Spectroscopic Techniques Laboratory provides FT-IR, UV–Vis–NIR and EPR measurements to internal and external users for chemical, optical and spin-sensitive characterization.

Companies can access established measurements with technical support, data processing and, when requested, interpretation or technical reporting.

From measurement to a usable result

Technical consultation

Before measurement

Align the sample, technique and information need.

Measurement data

Core output

Receive data generated with the agreed service route.

Data processing

Result preparation

Process and organise the data for technical assessment.

Interpretation or report

When requested

Add interpretation or technical reporting where included in the scope.

An established technical service

This page describes access to existing techniques and infrastructure within the ICMAB Scientific and Technical Services.

Need a custom experimental programme?

New methods, customised programmes, in-situ or operando measurements, device development and advanced scientific interpretation beyond the standard service should be discussed as contract research or collaboration with an ICMAB research group.

Discuss your spectroscopic characterization request

Describe your material, sample format, the information you need and any relevant measurement constraints so the technical team can assess the request.
