Innovations in Particle Characterization Particle Size Analysis of Pigments and Inks

If you are involved in the formulation of pigments, powder coatings, and inks, you might have questioned the following:

  • How does diluting the pigment or ink emulsion impact particle interactions?
  • Will there be any effects of agglomeration or flocculation?
  • Are the zeta potential values still reliable to determine stability after diluting the solution?
  • How do pH and conductivity values affect the samples?
  • What is the exact amount of titrant required to create a stable formulation?

O techniky aditívne výroby je veľký záujem najmä pri konštrukcii lietadiel. Kovový 3D tlač otvára úplne nové možnosti znižovania hmotnosti a následne znižovanie spotreby petroleja. Diely, ktoré predtým bolo nutné zostaviť z desiatok jednotlivých komponentov, možno teraz vyrábať priamo z jedného kusu. Pokrok vo vývoji aditívne výroby umožňuje vyrábať stále viac dielov vo veľkom množstve pomocou 3D tlače.

Prášky používané pri výrobe prísad musia spĺňať najvyššie štandardy kvality: Distribúcia veľkosti by mala byť úzka a musí byť známa čo najpresnejšie, aby bolo možné riadiť správanie materiálu počas procesu spekanie.

ASTM E3427-24 Standard

Standard Guide for measuring intensity, polydispersity, size, zeta potential, molecular weight, and concentration of nanoparticles in liquid suspension using laser-amplified detection / power spectrum analysis (LAD / PSA) technology.

  • Measure scarce and valuable samples as small as 2 microliters – at full strength
  • Measure at concentrations as high as 40 cubic centimeters per milliliter
  • No interference from dust or large contaminants
  • No need for dilution of inks, paints, or polystyrene standards to avoid changing ionic strength of the sample

Microtrac’s NANOTRAC FLEX and STABINO ZETA utilize unique technologies that can measure your samples undiluted or at higher concentrations.

  • The STABINO ZETA is the preferred choice for accurately determining zeta potential and colloidal stability
  • It can perform fast titrations and replace classical zeta potential measurement
  • Particle surface charge and interface potentials like the zeta potential and streaming potential are commonly used to characterize the stability of suspensions, emulsions, and nanoparticles

The Perfect Solution for Pigments & Inks

For accurate determination of zeta potential and colloidal stability, the STABINO ZETA is the first choice. It replaces the classical zeta potential measurement and has the ability to perform very fast titrations. Combined with Microtrac MRB's NANOTRAC FLEX DLS analyzer, the STABINO ZETA offers the highest flexibility in your laboratory!
  • Simultaneous determination of 5 measurement parameters within a few seconds:
    • Zeta potential, streaming potential, conductivity, pH value, temperature
  • Particle size as an additional parameter when combined with the NANOTRAC FLEX
  • Mix and Measure principal without prior knowledge
  • Innovative probe design enables measurement over a wide concentration range
  • STABINO ZETA software allows for real-time monitoring of your measurement
  • Sample volume: 1 ml, 10 ml
