NanoParticle Counter (NP Counter)
Nanoparticle Concentration Meter for Liquid Media

NP Counter

NP Counter Russian device for measuring number concentration of nanoparticles in liquid media

About the Device

NP CounterNP Counter (NP VISION LLC, Russia) measures the number concentration of nanoparticles in liquid media using a direct method. Its operation is based on the principle of ultramicroscopy, which allows visualizing nanoparticles dispersed in liquid. The measurement process takes several minutes, requires no expensive consumables, and offers high accuracy and reproducibility of results.

Operating Principle

The ultramicroscopy method allows measuring the number concentration of nanoparticles in liquid media. This experimental method was developed by Richard Zsigmondy, who received the Nobel Prize in Chemistry for this work in 1925. This method is a type of optical microscopy with a special way of illuminating the sample using a laser.

Software The "NP Vision"

Software The “NP Vision” software, specially developed for this method, allows finding images corresponding to scattering from nanoparticles in each video frame according to user-specified parameters and counting them.

Measurement Characteristics

  • Only 1 ml of sample is required for measurements.
  • Minimum particle size depends on the material (from 5-10 nm for metallic particles).
  • The method is applicable to spherical particles and nanoparticles of other shapes.
  • Samples with particle concentrations of 10^7–10^9 pcs/ml can be studied without dilution.

Application Areas

  • Nanoparticle synthesis
  • Colloidal gold and silver 
  • Liquid contamination control (water, fuels, oils)
  • Filter efficiency
  • Degradation of porous materials
  • Quantum dots
  • Magnetic nanoparticles
  • Exosomes (extracellular vesicles)
  • Nanodiamonds
  • Air pollution control
  • Human biological fluids
  • Microplastics
  • Carbon nanotubes
