High Throughput CD System
Recent trends in Combinatorial Chemistry and automated synthesis have lead to various new high-throughput measurement techniques. JASCO developed the high-throughput CD measurement system combing autosampler, syringe pump and flow cell unit with the J-1500. This system can accommodate dual 96 well plates (up to 192 samples) while keeping sample temperature constant. Software control allows samples to be recovered after measurement without waste for further analysis. The system shown can repeat a pre-determined measurement sequence such as: Suction - measurement - recover - wash - blank measurement. By using the Macro command program, the system allows automated scanning measurement at pre-determined parameters and/or temperature ramping measurement by using a Peltier thermostatted flow cell. In addition to CD, absorbance, scattering and fluorescence can be simultaneously measured.
