UV-Vis & UV-Vis-NIR Spectroscopy

Roy J. Carver Dept. Biochemistry, Biophysics, and Molecular Biology , Iowa State University The biochemistry teaching laboratories at Iowa State University have relied on the outstanding performance and reliability of the Cary 60 scanning spectrophotometers. Since 2000, our twelve Cary spectrophotometers have continued to be the workhorse in our teaching laboratories. A major concern for a teaching laboratory is the reliability of instrumentation, and the continued support and service provided long after purchase. After many years of heavy use in a teaching setting, all our Cary 60 instruments have proven to be of very high-quality with outstanding durability. We design our biochemistry curriculum to prepare students for research-based career paths that demand technologically curre View More

Research scientist, CEA-Leti, France "I recommend the Cary 7000 UMS because there is no alignment, no user intervention, no extra baseline, its fully automated and that allows for a streamlined workflow for material characterization” View More

School of Chemistry and Biotechnology, Swinburne University of Technology Agilent’s Cary 3500 with controlled stirring and wide range of temperature control options has converted me to use UV-vis spectroscopy to monitor processes in situ using this instrument. The stability of the signal allows for long term kinetic processes too, opening up a range of experiments I was unable to do beforehand due to drift. The intuitive software and data management prevents the loss of results and ensure well organized projects and archives. The Cary 3500 is most definitely an exciting advancement from any other UV-vis spectrometer I have used previously, expanding the flexibility to control more parameters while conducting research experiments.

ARC Centre of Excellence in Exciton Science School of Chemistry, University of Melbourne We are impressed with the fast scan, user friendly modular design and high throughput of Agilent Cary 3500 UV-Vis. In particular, the great temperature ramping rate and sensitivity makes our work easier. Our project uses UV-Vis to research how temperature affects the scattering properties of gold nanoparticles coated in PNIPAM polymer. As temperature increased over the 30 – 40 °C range, the polymer collapses and the particles aggregate; we are interested in understanding the dynamics of these processes. Wavelength scans at different temperatures, and thermal gradient scans are used to partially characterize these processes. We also do these measurements over a range of pH, salt concentrat View More
