Dynamic Light Scattering


Microtrac has been a global leader in laser diffraction instrumentation for over 40 years - by continuously improving the instrument technology, we offer customers a robust portfolio of laser diffraction instruments which is ideal for particle sizing and characterization.

The NANOTRAC FLEX In-Situ Particle Size Analyzer Delivers Fast and Accurate Analysis Capability

Powered by Microtrac MRB’s enhanced dynamic light scattering technology, the NANOTRAC FLEX is ideal for measuring particles across wide concentration ranges, using minimal sample volume. Named appropriately, the external probe grants the flexibility to measure suspensions from sub-nanometer to several microns, in-situ or on a lab bench.

FEATURES

  • External probe with 180° backscatter
  • Turn any vessel into a sample cell – the external probe allows you to dip and measure
  • Small sample volume required, as low as 5 µl
  • Amplified optical signal for unparalleled accuracy and sensitivity via Reference Beating
  • Measures particles ranging in size from 0.8 to 6,500 nm
  • No “a priori” knowledge of the particle size distribution is required
  • Ability to measure size and concentration simultaneously
  • Compliant to ISO 22412 & CFR21 Part 11
  • Numerous probe lengths available from 1.0 meter to 3.5 meters
  • Universal solvent compatibility
  • Molecular weight determination

The NANOTRAC WAVE II provides users with superior particle analysis capability by taking advantage of an enhanced optical signal, innovative probe technology, and advanced algorithms. Whether your material is ppm or near finished product, the WAVE II obtains fast, sensitive, and precise measurements of materials ranging from sub-nanometer to several microns.

The NANOTRAC WAVE II is a measurement system for direct automatic measurement of the electrophoretic movability and the Brownian motion as well as the thereof resulting Zeta potential and particle size.

FEATURES

  • Enhanced optical signal for superior accuracy compliments of Reference Beating
  • Unique probe design, fixed optics, and 180° backscatter collection enables fast and precise measurement across the widest concentration range – from ppm to near solids (40 % w/v)
  • No “A priori” or advance knowledge of the particle size distribution is required
  • Able to measure Zeta potential closer to iso-electric point by eliminating errors caused by electro-osmotic flow. ZP measurement ranges from -200 to +200mV
  • User-selectable data presentation modes:

Nanotrac Wave II Particle Size Analyser

The Nanotrac Wave II Q by Microtrac MRB combines the best of both worlds for nanoparticle size analysis; Microtrac MRB’s proprietary probe technology, adapted for a cuvette interface, facilitating fast measurements and the ability to dispose of the sample cell after use.

Using Reference Beating, an enhancement to traditional DLS, the Nanotrac Wave II Q delivers an amplified optical signal back to the photodetector, resulting in superior measurement accuracy for measuring size and molecular weight of nanoparticle suspensions.

FEATURES

  • Measures particle size from 0.8 to 6,500 nm
  • Simultaneously measure size and concentration
  • Cuvette error detection alerts
  • No blank measurement or prior knowledge of size distribution required – simply load cuvette and measure
  • Widest concentration range on the market from ppm to 40% w/v
  • Peltier temperature control device
  • Compliant with FDA 21 CFR Part 11
  • Compatible with 5 cuvette volumes:
