Suspended Solids

Samples containing suspended solids may cause a problem with the conventional fixed cross-flow or concentric nebulizers depending upon particle size. Solids that will pass through a 0.3 µm filter will not plug these nebulizers and will behave as if they are in solution with respect to the entire sample introduction process. Particles > 10 µm will not aspirate normally and are not likely to cause plugging. Many sample types have particulate that is easily visible to the naked eye and will cause difficulty with the cross-flow and concentric nebulizers. The Babington V-Groove, GMK Babington , Hildebrand dual grid, Ebdon slurry, Cone Spray, and Noordermer V-groove nebulizers are all popular choices. Other options include filtration to remove the solids and chemical treatments such as fusion, ashing, or acid digestion to dissolve the solids.
