Agilent Cary 630 Fourier Transform Infrared Spectrometer

Fourier Transform Infrared (FTIR) spectroscopy involves the interaction of infrared radiation with materials to obtain a spectrum showing absorption or emission at specific wavelengths. Through the use of either the Diamond attenuated total reflectance (ATR) or transmission sampling accessory, both unknown solid and liquid materials can be identified. CMDR primarily uses FTIR to identify the chemical composition of a wide range of marine debris polymers ingested by marine organisms and found in the environment.

 
TA Instruments DSC25 Discovery Series Differential Scanning Calorimeter

Differential scanning calorimetry (DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. DSC is widely used for examining polymeric materials to determine their thermal transitions. CMDR uses this instrument, coupled with FTIR, to determine polymer composition of marine debris. This method can also be utilized to detect copolymers, polymer degradation, and additives. This instrument comes with a 54-position autosampler, providing real-time heat flow data.
