The measurement of particle concentration is an important parameter in many applications and we can offer a number of alternative ways to measure true number size distribution depending upon the nature of the samples.
Liquid
ESZ - Coulter Counter Multisizer - the most versatile particle sizing and counting analyser available today, the Multisizer provides actual number and volume (mass) size distributions in one measurement in the overall size range of 0.4 - 1200 microns. The Multisizer measures a real parameter of individual particles, the actual particle volume. This produces an ultra high-resolution analysis which is unaffected by particle shape, colour, density, refractive index or composition. Small changes in particle number and size distribution, such as those obtained during dissolution or aggregation can quickly and easily be detected.
Light Scattering - Spectrex 2200
Suitable for both in-situ and flowing liquids, the Spectrex PC-2200 can be used for counting particles in a wide variety of liquids. Compact and portable the PC-2200 can be used for samples as small as 5ml vials or with a 'flow-thru' cell option for in line use. Software routines for NAS,SAE and ISO classifications are available.
Imaging - Fluid Imaging Technologies - FlowCAM
As well as counting particles in liquids such as river water, parenteral drug formulations, chemicals etc the FlowCAM also images particles allowing identification of contaminating particles to be made using the Visual Spreadsheet software. Particle parameters can be set up by the user to select specific types, sizes or shapes of particle and report data on each group. Particles from approx 1 micron to 1000 microns can be measured successfully. Watch real time imaging at http://www.fluidimaging.com/default.aspx
Airborne/Air Quality
We have available a wide range of instruments for measurement of particulates in air ranging from monitoring of diesel exhaust emmissions to cleanroom particle counters, filter efficiency testing or basic aerosol/atmospheric research. High flow rate Condensation Particle Counters are available with water as a working fluid for critical production environments. Electrical Particle sizers, particle impactors, samplers and a Nano Particle Collector for sampling charged aerosol nanoparticles.
