Service

Electron and Optical Microscopy

The service provides fundamental tools for the observation and analysis of microorganisms or their microstructures. Advice and permanent technical support by the service staff facilitates the scientific tasks.

The service is open to a wide scientific community, including the ICM and other CSIC centers, public research organizations and private companies.

Calibration of the scanning electron microscope is performed regularly. Calibration standards certified by the National Institute of Standards (NIST) of USA and the National Physical Laboratory (NPL) in the United Kingdom, which meet the ISO-9000, are available. 

An annual review by the Hitachi official technical staff (ISO-9001) is performed to certify proper operation.

Service benefits on request and availability.
