Superior Dry Powder Feeder
Automatic control of sample feed rateLA-950 monitors amount of sample
supplied by the vibratory feeder. Automatic feed back control keeps constant mass flow rate of powder during measurementThis is CRITICAL
– More reproducible, robust– No ghost peaks– No cutting off results– Fewer headaches!
Unique to HORIBA

Calcium Carbonate
Comes in two varietiesGround CaCO3
– Typically broader size distributions– Irregular particle shape
Precipitated CaCO3
– Can be narrow distributions– Can produce any of several morphologies
Size, color, and chemical composition determine applicationRoofing, Stucco, Grout, Masonry blocks
