New equipment at NanoQAM

Three new instruments

In the past two months, three new scientific facilities have been added to the fleet of instruments managed by our research center. Like other equipment, these are accessible to academic and industrial players.

Micropipette drawing machine

The first piece of equipment, which belongs to Pr. Janine Mauzeroll, is a Laser micropipette drawing machine (LBMP). This P-2000 micropipette drawing machine incorporates a heat source based on a CO2 laser which is suitable for working with most conventional glasses (quartz, borosilicate and aluminosilicate). The P-2000 can stretch electrodes with a diameter as small as 0.03μm. Glass tubes with outside diameters of 1.5 mm (quartz) or 1.8 mm (conventional glasses) can be used with the P-2000, but the best performance is obtained with glass tubes of 1.2 mm in diameter or less. Finally, the P-2000 is ideal for applications such as spray-nano or near-field optical microscopy.

Solar simulator

The second equipment, which belongs to Pr. Benoit Marsan, is a solar simulator. This is in addition to the UV simulator already managed by our research center. This solar simulator, 500W (ozone lamp), based on a total reflection design, allows to create a uniform projection of sunlight, without chromatic aberration.

GPC triple detection

Finally, the last piece of equipment, which belongs to Prof. Jérôme Claverie, is a set of 3 detectors: a dynamic light scattering detector (QELS), an interferometric refractometer (RI) and a multi-angle light scattering detector ( MALS). The latter are coupled to a gel permeation chromatography instrument (at room temperature) and henceforth allow the separation and the simultaneous determination of the radius and the molar mass of molecules and polymers.

Future uses

Anyone interested in using these three instruments or interested in being trained on them for autonomous use, must imperatively contact Dr. Gwenaël Chamoulaud beforehand.
