The AccuSizer FX and FXnano are high concentration single particle optical size sensors (SPOS) that have the sensitivity to detect small differences in particle size distributions. They were designed to allow particle size monitoring to go from the R&D laboratory to the process line with a minimum to system reconfiguration.
The AccuSizer FX utilizes a focused beam technology that allows the sensor to focus on a specific area of the flow channel to count and size individual particles starting at 0.15 microns and at concentration levels exceeding 10 million particles per mL. These are concentration levels that are millions of times higher than traditional sensors. Although this type of approach has been tried by other techniques to monitor high concentration process streams it has been plagued by low resolution ad accuracy. The FX utilizes a patented electro-optical configuration that maintains the same levels of resolution and accuracy found in our traditional SPOS sensors.
The FXnano provides a summation signal that extends the lower size limit of the sensor below the standard FX sensor. Classically one of the limiting factors in the lower size limit of single particle optical sizers was the need to find diluents that are clean enough so that they do not add or make up most of the background counts of the sample being analyzed. The tremendous increase in particle levels with the FX sensors makes it easier to reach lower sizes where background count levels are no longer a concern. In the past a few thousand counts in the background would cause great concern but now with concentrations exceeding 10 million a few thousand background counts do not affect the overall distribution. This becomes critical when looking at nano particles below 0.5 microns.
