Festive New Orleans, Louisiana, was the site of the 61st annual Biophysical Society Meeting, held February 11-15, 2017. Quantum Northwest’s booth featured a variety of products of interest to biophysicists using optical spectroscopy. Kelcey Boss, Enoch Small and Jeanne Small represented Quantum Northwest at the Biophysical Society Meeting’s exhibit. Quantum Northwest’s chief scientists are all biophysicists by training, and the annual Biophysical Society Meeting is the company’s annual homecoming celebration.
The Turret 6
Featured at the booth was the Turret 6, with rotation and magnetic stirring controlled with the TC 1 Temperature controller. The program T-App was used to run a pre-programmed script, directing the TC 1 to move the Turret 6 at precise intervals, rotating the Turret 6 through its six cuvette positions.
Other products on display at the Biophysical Society Meeting included products for UV/Vis absorption spectrophotometry (the t2 Sport and t2x2 Sport Dual cuvette holders), laser spectroscopy (the Flash 300), fluorescence (the Luma 40), and circular dichroism (the CD 250). Additionally, a qpod 2e was on display, offering temperature control and magnetic stirring for fiber optic spectroscopy (absorbance, fluorescence, scatter, and Raman).
Partner companies at the Biophysical Society Meeting
Quantum Northwest offers Peltier-based cuvette holders that fit into a variety of “destination spectrometers.” The partnerships with the companies that make the destination spectrometers are important to Quantum Northwest. Many of these companies were also exhibiting at the Biophysical Society Meeting, including Horiba Scientific, Applied Photophysics, Edinburgh Instruments, ISS, PicoQuant and Olis.
This year’s Molecule
Quantum Northwest serves a variety of forms of spectroscopy, including pulsed-laser photoacoustic spectroscopy (PAS). In PAS, the energy of a laser pulse is absorbed by a molecule in solution. Part or all of the absorbed energy is released as heat, generating a rapid expansion of the solution around the molecule. This expansion causes an ultrasonic acoustic wave to be generated… hence, “We torture molecules with light and listen to them scream.” The screams may be detected using an ultrasonic transducer clamped to the side of the cuvette.

Next year’s Biophysical Society Meeting will be held February 17-21, 2018, in San Francisco, California.
