The A can count particles in large liquid volumes, with room for 1 liter beakers. The newest addition to the Online family, the POU Point-of-Use monitor, is a small inexpensive unit that can be used for applications that require little or no dilution.
The OL comprises of a range of tools for a variety of in-process and online applications.
AccuSizer AD – Analytical Solutions
All AccuSizer systems measure particle size and concentration using accuiszer sensor, counter, and fluidics configuration. These OL systems represent a range of Autodilution fluidics which can be chosen for optimal measurement of your samples. Single Particle Optical Sensing makes the meaurement accurate while Autodilution and innovative electronics make it fast and acusizer.
Nanoparticle systems are often extremely concentrated. The AccuSizer AD provides exponential autodilution to your sample, automating sample preparation while still providing accurate concentration information. Several fluidics configurations are available to deliver the sample to the sensor directly or with autodilution to avoid coincidence errors.
Large amounts of concentrated emulsions TNA, drug delivery, food, soft drinks, paint, coatings, etc. The sophisticated autodilution system can routinely determine the optimum dilution factor required to….
So in addition to having systems that can handle concentrated dispersions like emulsions or inksthe POU adds the monitoring of contamination which will have a big impact on pharmaceutical PAT.
In either case, time and money are lost. This module can easily be incorporated with existing AccuSizer units.
The AccuSizer AD provides exponential autodilution to your sample, automating sample preparation while still providing accurate concentration information. The APS uses a unique two stage fluidics system, providing the ability to measure particle size and count in high concentration suspensions. The AccuSizer can also be linked via a single computer to the Nicomp A series of sensors based on the single particle optical sizing SPOS technique using light extinction, scattering, or in combination are available.
Company Profile Email Us. The AccuSizer is the cornerstone of the modular family of instruments. While there are several established techniques in the field of particle sizing that can be used to measure the particle size distributions of nano-dispersions, few of them…. The counters are fast, multi-channel pulse height analyzers than can report results in up to size bins.
However, it has a much wider size range, a much higher counting rate and is compatible with any liquid or gasand relatively immune to clogging. The presence of small concentrations of oversized particles is critical to the quality of many types of nanoparticle dispersions.
A failed product will have to be returned to the factory floor for further processing or junked. Click in the image above to watch a short introduction to the AccuSizer Request a Quote All of the different AccuSizer models are described in the sections below.
Oversized particles can signal that a dispersion is unstable or that it will clog filters.
AccuSizer 7000 AD
Oversized particles can signal that a dispersion is unstable or that it will clog filters. Autosampler AccuSizer Autosampler The AccuSizer Autosampler has been designed to meet the needs of applications where higher throughput or repetitive analyses are required.
Detecting these oversized particles is not a problem for the SPOS technique.
The dynamic range varies depending on the size of the sensor being used. These alternative techniques require the use of complex mathematical algorithms and can produce only a rough approximation of the true PSD, having limited sensitivity and very poor resolution. This approach is in sharp accusiizer to “ensemble” methods, such as Fraunhofer diffraction and sedimentation, which must process information produced by many particles simultaneously.

These tails of large particles usually greater than 1 micron can have huge consequences for a wide range of industrially important nanoparticle systems like inkjet inks and CMP slurries and emulsions.
Using the Accusizer AD or the APS, the determination of oversized particle concentrations in the quality control lab can be performed. In addition, the A can perform precise…. A more efficient approach would involve in-process monitoring using the OL system. Both of these needs are met with Particle Sizing Systems patented autodilution system.
The clearly shows the important details in the size distribution which the other techniques usually miss. Accurate particle concentrations require accurate dilutions and busy laboratories require fast dilutions. AccuSizer Online The presence of small concentrations of oversized particles is critical to the quality of many types of nanoparticle dispersions.
Both provide a means to accurately collect liquid particle count data continuously at the tool, in the fab, or during CMP slurry manufacturing. AccuSizer Online AccuSizer Online The presence of small concentrations of oversized particles is critical to the quality of many types of nanoparticle dispersions. I agree to the Terms and Privacy Statement. It uses the principle of light obscuration to count and size particles one at a time.
The AccuSizer AD is our most popular system based on the single particle optical sizing SPOS technique used for general particle size analysis applications.
