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.

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
