A high-throughput (high throughput is the ability to process large numbers of samples) and companion informatics system has been developed and implemented. High throughput is defined as the ability to autonomously evaluate large numbers of samples, while an informatics system provides the software control of the physical devices, in addition to the organization and storage of the generated electronic data. This high throughput system includes both an ultra-violet and visible light spectrometer (UV-Vis) and a Fourier transform infrared spectrometer (FTIR) integrated with a multi sample positioning table. This method is designed to quantify changes in polymeric materials occurring from controlled temperature, humidity and high flux UV exposures. The integration of the software control of these analytical instruments within a single computer system is presented. Challenges in enhancing the system to include additional analytical devices are discussed.
Simultaneous high-resolution energy and picosecond timing measurements have been established with an 8-channel, 14-bit, 500 MS/s digitizer coupled to semiconductor and scintillation radiation detectors, resulting in performance equivalent to that obtained with analog electronics. By interpolating between the 2 nanosecond time stamps associated with the sampling frequency, timing up to few tens of picoseconds is achieved. Energy resolution and linearity are determined to be excellent. Coincidence and precise lifetime measurements performed indicate the utility in complex gamma-ray spectroscopic studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
