Cary 50 (SPECS)

The Instrumentation Laboratory operates one dual beam, research grade, spectrophotometer.

The instrument is used by researchers and students for a variety of colorimetry based tests including phosphorus, sulphate and chlorophyll and have been used to study colouring in gem stones. Pulp and paper chemists have used the instrument for studies of lignin. The instrument uses the Cary WinUV software.
