Samples
Far-IR supports any phase of sample - gas, solid, or liquid - with required amounts varying depending on the technique. While most work on Far-IR is gas-phase high-resolution spectroscopy, the versatility of infrared experiments means virtually any sample can be run at Far-IR.

Access
Purchased Access
Purchased access offers quick and accurate solutions to proprietary questions. CLS scientists develop experimental plans based on clients' needs, collect and analyze data, and provide detailed reports with key answers to critical questions.
Peer-Reviewed Access
Academic clients can submit proposals through a peer review process. Beam time is granted based on scientific merit, with the expectation that any results will be published. In special cases, rapid access is also available for instrument or beam time.
