Particle Size Distributions
The NANO-flex® II 180° DLS system measures size distributions in the range of 0.3 nm to 10 µm.
The unique 180° back scattering principle of the Nanotrac® allows measurement of highly concentrated samples, without interference from the effect of multiple scattering. The heterodyne design of the NANO-flex probe means that some reference light from the laser is reflected straight to the detector to act as a reference and significantly improves the signal-to-noise ratio of the NANO-flex compared to other DLS instruments.
The NANO-flex® is designed as a flexible measuring probe with 8mm diameter. It can therefore be used for a whole range of in-situ particle sizing scenarios, whatever the vessel – be it 96 well plates, beakers, vials or even in the Stabino zeta potential titration beaker for simultaneous size and charge experiments.
- 180° heterodyne dynamic light scattering (very short light path in the sample avoiding multiple light scattering).
- Measurement in a variable concentration range (0.01 up to 40% w/v) from 0.3nm to 10um particle size.
- Dip in probe offering online in-situ size measurements
- Solvent resistance
- Usable in combination with Stabino® for simultaneous size, zeta potential and titration/stability measurements
The NANO-flex can also be used for in-line applications, such as during a milling process. The IPAS accessory allows the NANO-flex to take accurate size measurements either during a process flow or in a stirred beaker, by isolating a small sub-volume of sample for measurement, before releasing it back into line, in a completely automated solution.
DLS applications with the NANO-flex® nanoparticle measurement system module are almost unlimited, provided the viscosity of the sample is in the Newtonian range, a condition for the free Brownian movement in the fluid and for the accurate calculation of size. The liquid medium of the particles can be of organic or aqueous nature. The critical coagulation point of a dispersion can be determined by measurement of size and potential with the Stabino®.
