What your nano lab actually checks
Size, zeta and MW in one
Particle size, zeta potential (±200 mV), molecular weight and concentration on the same stable 180° backscatter optics — with automated titration for isoelectric point and temperature control. No second instrument, and calculations conform to ISO 22412 and 21 CFR Part 11.
An applications engineer on the line
Size, zeta, titration and compliance method development from engineers who run characterization in-house at ATO Lab. Sub-4h reply, NDA standard.
The Microtrac NANOTRAC WAVE II is an all-in-one dynamic light scattering (DLS) analyzer that measures nanoparticle size, zeta potential, molecular weight and concentration in a single compact benchtop instrument — 0.3 nm to 10 µm. It uses the same 180° backscatter Laser Amplified Detection and Frequency Power Spectrum model as the NANOTRAC series (up to 10⁶× the signal-to-noise of standard DLS), with temperature control, automated titration, and calculations conforming to ISO 22412 and 21 CFR Part 11.
Why nanoparticle labs choose the NANOTRAC WAVE II
Size, charge and molecular weight from one compliant instrument — no separate zeta analyzer.
Size + zeta + MW in one
Particle size (0.3 nm–10 µm), zeta potential (±200 mV), molecular weight and concentration on the same stable optics — no second instrument, no re-plumbing between measurements.
Robust zeta by field reversal
Rapid electric-field sequencing prevents electro-osmosis, and mobility is derived from the power-spectrum ratio — reliable charge even on high-concentration samples.
ISO 22412 & 21 CFR Part 11
DIMENSIONS LS calculates to ISO 22412 and supports 21 CFR Part 11 workflows — the data-integrity features regulated pharma and QC labs require.
Titration & temperature control
Automated titration maps zeta vs pH for isoelectric point, with active temperature control (+4 to +90 °C, ±0.1 °C) for stability and aggregation studies.
How Additive Plus supports it
A configured, installed analyzer with a size-and-zeta method dialed in on your material.
Configure to your sample
We match the size and zeta cells, titration and solvent setup to your material and concentration before it ships.
Install & train
Factory-trained engineers install and train your team on DIMENSIONS LS — size, zeta, MW and titration workflows.
Method & QC support
We build the SOP — reproducible size and zeta reporting, isoelectric-point titrations and a 21 CFR Part 11 setup where needed.
