Confirming Accurate Particle Counting and Sizing on MFI Systems

Polystyrene beads are ideal for particle sizing and sensitivity testing because they easily trigger the MFI imaging detector, yielding consistent and precise sizing and concentration results over a large size range. To ensure correct usage, this application note discusses recommended guidelines on how to use bead calibration for sizing and concentration verification on the MFI 5000 series with or without the Bot1 autosampler.
