Principle of Operation
The LA-930 uses Mie Scattering Theory (laser diffraction) to measure particle size over the range of 0.02-2000μm. The LA-930's optical design is optimized for light-scattering measurements, with an 87-element logarithmic detector system and automatic alignment, together with the shortest wavelength light sources available to provide full range measurements and the ultimate in sub-micron accuracy and resolution. The advanced design avoids the long optical bench previously required to measure larger particles, without combining multiple analysis methods in one measurement or giving up capablilities in the sub-micron range.
Accessories
Dry Analysis - For powdered materials, the PowderJet Dry Feeder
system provides a simple, yet effective, method for analyzing both free-flowing and cohesive dry powders.
Automation - Adding automation accessories provides all the advantages of continuous, non-stop, unattended operation, including reduced labor costs, elimination of human error, and exceptionally reliable, repeatable measurements.
Fraction Cell / Holder - The curvette-type Fraction Cell allows liquid suspensions as small as 5 ml to be measured, making it perfect for measuring very valuable, extremely small, or hazardous samples.
Pharmaceutical Regulation Compliance - A 21CFR Part 11 compliant software package is available, as well as a full instrument validation package.
