The Microfluidic Resistive Pulse Sensing (MRPS) instrument used at PTL to measure nanoparticles in suspension is based on the Coulter Principle also known as the Electric Sensing Zone technique. Si...

Laser Diffraction (also known as Static Light Scattering) is one of the most widely used particle sizing distribution techniques.  Samples, which can be analyzed either as a liquid suspension or a...

Electric Sensing Zone, also referred to as the Coulter Technique or Coulter Counter, is a true high-resolution, high-speed particle counter and particle size distribution analyzer. It covers a nomi...

Light Obscuration, also referred to as Single Particle Optical Sensing (SPOS), is an analytical technique of high resolution capable of detecting a small percentage of outliers. It can also be used...

Dynamic Light Scattering (DLS) is a commonly used term to describe a technique which measures the particle size and estimated distribution of submicron particulate systems.  In addition, the terms...

Nanoparticle Tracking Analysis (NTA) technology, which is one of the first commercially available technologies allowing high-resolution particle size distribution on a number-weighted basis and con...

Image Analysis is a powerful analytical technique which can provide additional information on a sample compared to just “particle size” and distribution. The majority of particle sizing techniq...

Sieving has been around since the time of the ancient Egyptians and can be considered the backbone of particle size technology.  Sieving’s continuing popularity is due to the technique’s funda...

This classical analytical technique determines the average particle size by measuring the pressure drop across a packed powder bed using a water manometer.  The pressure drop is a function of the ...
