The XO in-process particle sizer for dry powder processes has the unique CellClean feature that minimises maintenance downtime. A rapid air pulse to clean the sample windows ensures sampling is continuous and uninterrupted by cleaning or changes in the process line.

With sampling of in-process particles between 0.1 to 3000 microns, the widely acclaimed XO particle sizer has a unique feature, not seen on any other sizer on the market. The flow path within the sample cell, where laser diffraction is used to measure particle size, is encased by a curtain of air to contain the flow of particles through the analyser. This curtain of air called the purge and sheath air, keeps the cell windows free from contamination so that particles can be accurately measured by light scattering by the laser onto the fourier lens.

If there is a sudden change in the process line, for example a sudden pulse in pressure, valve failure or even a stickier powder is being sampled, the windows within the sample cell may in some circumstances be obscured, resulting in downtime in sampling. Manual cleaning of other particle sizers on the market, is arduous as components need to be stripped down and cleaned, after disconnecting the instrument from the process line. The CellClean function, which is standard on all XO particle sizers, can provide a quick pulse of air directly across the cell windows to blast off any contamination and rapidly clear the windows, restoring effective sampling in seconds.

Stuart Barton, Managing Director says “This function can add real practical value to a process. If you can continually monitor particle size, without the interruption of offline cleaning, this saves time and money on your process.” Stuart adds “The great part is that the CellClean function can be automated at regular intervals as part of a routine sequence, meaning no operative intervention is necessary. The CellClean feature helps optimise powder processing by ensuring in-process particle sizing is continuous and always in real-time”.
