Dynamic light scattering particle size analyzer PA-1197LW

laserstatic light scatteringfor the food industry

Product overview
PA-1197LW wide-range laser particle size analyzer integrates PA series technical features and introduces a dual-mode measurement capability. It measures both nanometer and micron particles by switching between Photon Correlation Spectroscopy (DLS) for the nano range and full-range Mie scattering for the micron range with a one-touch switch in seconds.

Application area
Suitable for scientific research institutes and industrial quality control in electronic materials, inks and pigments, polymer latex, coatings, papermaking, chemicals, ceramics, pesticides, pharmaceuticals, coal-water slurry, cosmetics, abrasives, food, calcium carbonate, talc, kaolin, alumina, rare earths, magnesium powder, catalysts, refractory materials, cement, graphite, marine sediment analysis and other powder, emulsion and slurry particle size distribution tests.

The report shows
Software supports Chinese and English interfaces. Multiple report formats available (cumulative distribution, normal distribution, RR distribution, etc.). Reports include cumulative and interval particle size distribution data and curves, histograms, characteristic particle size values (D3, D10, D25, D50, D75, D84, D90, D97), volume and area mean diameters, specific surface area and related data.

Instrument advantages

• Inverted Fourier optical system with large single-beam and combined lenses reduces stray light from sample cell reflections; large-angle scattered light is not limited by lens aperture, improving resolution.
• 128-level multi-element detector and high-gain, low-noise photomultiplier enable forward, side and backscattered signal acquisition via dual-source channel detection.
• Proprietary polydispersity analysis algorithm rapidly analyzes mono- and polydisperse systems; supports mass concentration and relative concentration measurements for nano samples and real-time sample temperature monitoring to avoid temperature-gradient errors.
• High-quality optical glass and a customized 2.5 mL thin-slit detection cell preserve precious samples; two automatic sampling systems (non-circulating, non-recycling) enable recovery of trace samples after testing.
