Concentration Range: 105-1012 particles/mL

Sample Size: 40 μL

Fluid composition: requires samples in an electrolyte solution. Some organic solvents may not be suitable.

     
 

 NanoBrookOmni (DLS)

The NanoBrook Omni particle size and zeta potential analyzer allows for fast, routine, submicron measurements of size and zeta potential. Based on the principles of Dynamic Light Scattering (DLS) for particle sizing and distribution, and on Doppler velocimetry (electrophoretic light scattering, ELS) for zeta potential, most measurements only take a minute or two. The instrument also includes Phase Analysis Light Scattering (PALS) measurements for samples with low mobilities (in saline and PBS).

Specifications:

Range: < 0.3 nm to 10 μm, depending on refractive index and concentration

Zeta potential: 1 nm to 100 μm, sample dependent

Three measurement angles: 15°, 90°, 173°

     
 

 Nano DS (DLS-SLS)

Dual Scattering Particle Size Analyzer which utilizes Static & Dynamic Multi angle Laser Light Scattering (SLS & DLS) for measurement of size and size distribution of particles in the range of 0.3 nm to 10 μm. Measurements can be carried out at scattering angle from 10° (front scattering) to 150° (back scattering) with angle resolution 0.01°.

     
 

NanoSight NS500 (NTA)

The NanoSight utilizes Nanoparticle Tracking Analysis (NTA), a technique which combines laser light scattering microscopy and a video imaging system for sizing of particles between approximately 50 nm and 1000 nm. After recording a video of the sample illuminated by a laser, the NTA software identifies and tracks the individual particles in the field of view (appearing as point-scatterers) which are moving by Brownian motion. The rate of diffusion (speed) of each individual particle captured on film is related to its size according to a modified Stokes–Einstein relationship. Using the total number of measured particles in a given size range, the concentration of particles per size bin can be calculated by extrapolation using an approximate measuring volume estimated by the manufacturer. Detection limits (smallest size) depend on the refractive index of the nanoparticles analysed.

 

     
 

 Pycnometer

The pycnometers are used for the true volume and density analysis of powders, foams and bulk solids. The gas pycnometer measures the true volume of solid materials by employing Archimedes’ principle of fluid displacement and gas expansion (Boyle's Law).

 A wide range of sample cell sizes are easily interchanged to accommodate many different samples. For measurements of extremely small amounts of material, the Micro-Ultrapyc 1200e provides three interchangeable cell sizes of 4.5 cm3, 1.75 cm3 and 0.25 cm3 capacity.

 Calibration, sample conditioning, operation of valves and calculation of results are completely automatic. Samples are quickly and automatically analysed as many times as necessary to achieve the user desired % deviation from mean at the specified number of runs.
