Microtrac Milestones


The VERDER Group entered into an agreement to acquire the American Microtrac, Inc. and the Japanese MicrotracBEL Corporation from Nikkiso Co. Ltd.


The Microtrac Sync is introduced to will provide customers with more information about their particles than ever before. The system integrates the world’s leading laser diffraction technology with the leading dynamic image analysis on the same bench with the same GUI. Microtrac’s Sync is synchronizing size and shape measurement – one sample, one bench, one sample flow path, one sample cell, one analysis.


The Nanotrac Wave is introduced to provide particle size, zeta potential, and molecular weight analysis in one instrument through its modular product platform design. For the first time, DLS users have the ability to reconfigure their instrument to satisfy a wide variety of application demands.


Image or shape analysis capability for liquid suspensions is added to the Microtrac S3500 family of particle size analyzers. The SI analysis module has a measurement range of 10 to 800 microns for shape analysis and can be combined with any S3500 or Bluewave analyzer that is configured for wet circulation.


Zetrator auto-titration system is introduced to add and automate charge titration control for the Nanotrac and Zetatrac products. The system is the first to offer a five titrant dosing pump option to maximize control for the most demanding applications.


Zetatrac extension of the Nanotrac family is introduced to measure particle size and zeta potential without changing samples.
Microtrac introduces advanced power spectrum modulation analysis.


Bluewave diffraction instrument introduced that uses blue lasers (not simply blue light sources) to produce the highest resolution and sensitivity available in diffraction instruments.


Microtrac releases the S3500 analyzer and Sample Delivery Controller (SDC) which provides advanced sample mixing and maximum organic solvent capability.

Nanotrac line gets another boost with the newly designed NAS automated sampler for nano suspensions.


The UPA electronics are overhauled to extend measurements down to the sub-nanometer range, giving birth to the Nanotrac family of analyzers.

FLEX software introduced to satisfy advancing computer features and to provide users with unparalleled flexibility.

Security software controls to meet the demand of FDA 21 CFR Part 11 are added to the Microtrac for Windows software.


The Nikkiso Company LTD procures the Microtrac product line from Honeywell and restructures the team of experienced employees as an independent USA corporation. Microtrac Inc. is born.


A Tri-laser system for diffraction particle size measurement is introduced. This technological leap essentially replaced the differential polarization method employed in the SPA models. Three-laser technology allows for better analysis and application of Mie scattering concepts.


Microtrac ventured into the field of dynamic light scattering with the release of the Ultra Fine Particle Analyzer (UPA) measuring 0.005 to 3 microns incorporating a fiber optic probe design to measure high concentration slurries. UPA becomes a worthy replacement for photon correlation spectroscopy (PCS).


The first solid-state detector instrument (model 7997) was shown at Pittcon. The model 7997 employed a solid-state, non-linear (logarithmic) detector array, effectively eliminating all moving parts. This was also the first use of laser diodes as replacement to helium gas lasers.


The first commercial laser diffraction analyzer, Microtrac (Model 7991) was sold in the U.S. It had a measuring range of 2 to 176 microns and measured particles only as an aqueous slurry. An on-line particle size monitor (7981) was introduced that same year.
