By using Insplorion's instrument, we can offer our customers:
To monitor processes in/on nanoparticles and thin films in situ and in real time
The instrument allows for monitoring of processes in the nanoscale, occurring for example in/on nanoparticles, nanostructures and on thin films. Real-time measurements can be made in-situ (i.e. on a functional nanostructure) with a temporal resolution of ms.READ MORE
To study a large variety of processes
Processes that can be investigated include adsorption/desorption, phase transitions, diffusion in porous films, light trigger, temp change triggers, volume/shape changes, reduction/oxidation, temperature changes (“optical nanocalorimetry”), etc.
Flexible choice of substrate material and surface chemistry
Any non-metallic material that can be deposited as a thin compact or porous film onto our sensor chips can be used as support for the process to be studied.
Practically relevant temperature and pressure
For XNano, temp can be varied from room temp to 80 C, and for the X1 in the gas phase up to 600 C. NPS as such has exceptionally low temp sensitivity allowing for ramping and studies of temp triggered processes.
Complete system includes hardware, software, hands on training and support.
Insplorion’s software provides user-friendly measurement control and programming as well as analysis of up to six measurement variables for each of the two sample positions simultaneously and in real-time.
During an experiment in Insplorion’s instrument, an optical extinction measurement is made through a quartz measurement cell/reactor in which the sensor chip is mounted (see figure below). The extinction measurement involves the detection of transmitted light, from a collimated white light source, through the sensor chip (via an optical fiber and the reactor walls) as a function of wavelength by an optical spectrometer (via a second optical fiber). The optical extinction spectra caused by the sensor chip, are detected with sub-second time resolution.
The optical response of the NPS sensor chips is characterized by a distinct peak at a certain wavelength in the extinction spectrum. The peak is caused by the strong interaction of the nano disk sensors with light at the LSPR, through absorption and scattering. During an NPS experiment, the spectral position of the LSPR peak (i.e. the precise color of the sensor chip) is monitored as a function of time during a process that one wants to study/monitor e.g. where the sample material on the chip is interacting with molecules in the gas phase (see figure below) or is exposed to a temperature change.
The color changes can be measured in real time (ms) with 10-2 nm spectral resolution. It can then be related to the kinetics of a chemical process taking place in/on the sample material (phase transition), changes in the surface coverage of a certain atomic/molecular species on the sample surface or the chemical energy dissipated by a chemical reaction running on a Nano catalyst.
