Product Description

The VASCOTM nanoparticle size analyzer is a unique instrument for nanoparticle suspension and colloidal characterization, based on the Dynamic Light Scattering (DLS) .




Key benefits:

  • High detection efficiency in opaque/dark media, as well as in diluted solution thanks to a DTC patented system
  • Extended sample concentration range (up to 40%*)
  • Reduce sample preparation (no filtration or dilution)
  • Polymodal and complex sample analysis
  • No consumable
  • Solvent-proof sample cell

* Depends on sample and VASCO model


Technologies & innovations

VASCO combines :


  • Unique embedded sample cell made of a silica prism and backscattered light detection
  • Dual Thickness Controller (DTC) : patented system allowing measurement of diluted sample as well as dark / concentrated ones, without dilution
  • Flusher to remove dust and bubbles
  • Advanced Padé Laplace algorithm


Main characteristics

  • Based on Dynamic Light Scattering (DLS)
  • Particle size (diameter) : 0,5 nm – 10 μm
  • Sample concentration : 0.1ppm – 40%w/v *
  • Optical filter option to improve measurements on fluorescent samples
  • On-line sample cell option → size kinetics study
  • NanoQ proprietary software
  • Compliant with ISO 13 321 – Particle size analysis – Photon correlation Spectroscopy & ISO 22 412 – Particle size analysis – Dynamic Light Scattering

NanoQ

A software fully-dedicated to nanoparticle size measurements for the VASCO series featuring :


  • User-friendly and intuitive GUI
  • User-defined Standard Operation Procedures (SOPs)
  • Measurement replay mode for post-data treatment
  • Exhaustive solvent database
  • Standard Cumulant and unique Padé Laplace algorithms for complex colloids analysis
  • Unique indebted simulator for measurement interpretation and pedagogic purpose
  • Report editor for results presentation and saving
  • User management database

NanoQ is designed to guide the user in a very simple and intuitive way, through the different steps of a measurement. Its access menu allows to select in one click an operating mode :

  • Measurement
  • Simulation
  • Import data/replay
  • User Management


NanoQ control interface

  • All information (Sample, Device, SOP, Measurements, etc.) accessible on the same panel
  • No tedious cascaded menus or scrolling bars
  • Measurements started and analyzed with a few clicks


Two analysis algorithms

  • Standard Cumulants algorithm monodisperse sample measurement (average size and PDI)
  • Advanced Padé Laplace algorithm complex / polymodal samples analysis


Two acquisition modes

Continuous mode, which allows to :


  • Integrate correlated signal for an undefined time period
  • Stop measurement and make analysis at your convenience
  • Grab correlogram at any time and make preliminary analysis without stopping the measurement


Statistical mode:


  • User settable multi-acquisition measurements
  • Use of Padé Laplace algorithm
  • Dedicated to size kinetics monitoring or to complex sample size distribution analysis


The Analysis page

A complete view on the results :


  • Size distribution and histograms from the Cumulants and Padé Laplace algorithm analysis
  • Display of measured correlograms with their fit and residues
  • Step-by-step results display and sorting
  • High accuracy analysis

Statistical mode :


  • User settable multi-acquisition measurements
  • Use of Padé Laplace algorithm
  • Dedicated to size kinetics monitoring or to complex sample size distribution analysis


A unique indebted simulator

  • Create virtual measurement sequences with user defined size distribution
  • Visualize easily impact of samples characteristics (viscosity, RI, temperature,) device settings and noise level on results analysis
  • Interpret measurement results for complex sample analysis


Solvent Database

More than 200 referenced solvents

Refractive index and viscosity data vs. temperature

It allows you to :


  • Import your selected solvent properties in just one click
  • Create and add your own solvent to the data base
  • Define its characteristics vs. temperature with various predefined interpolation models
  • NanoQ integrates many other advanced functionalities (customizable report edition, measurement replay mode, advanced analysis high accuracy mode, ) that we invite you to discover on our video. For more information, please contact us.
