Microtrac’s staff commits to the relentless pursuit of perfection and to achieving 100% customer satisfaction globally through our product and service offerings.
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 analysers. 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 analyser 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 maximise 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.
ULTRA model of Nanotrac is launched providing superior sensitivity to miniscule amounts of the smallest particles.
Turbotrac Dry Powder dispersion system is developed to provide auto-sequence operation and unattended sequencing.
Microtrac releases the S3500 Analyser 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 analysers.
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 UPA product family was upgraded with a universal solvent probe tip design to address applications where immersion into organic solvents and caustics is required.
Within the new platform, a Linear Dry Feeder (LDF) option is introduced as an alternative to the Vibratory Dry Feeder (VDF) option that was carried forward from the Series 9300 family. Both feeders are controlled through the Dry Powder Controller (DPC) which is designed to sit atop either the ASVR or VSR fluid circulation units.
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.
Automated x-y sampler introduced for Ultrafine Particle analyser.
The UPA line is expanded to include the world’s 1st Fiber Optic External Probe Particle Size Analyser – UPA250.
The Series 9300 line is expanded to include Dry Powder Sampling capability. The new feature is made available for models SRA150 and X100 as well as the newly introduced Large Particle Analyser model SRA200 which offers a size measurement range of 2.75 to 2000 microns.
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.

Full Range Analyser (FRA) with range 0.1 to 704 microns is introduced, the first optical bench to use auto-alignment.
Microtrac ventured into the field of dynamic light scattering with the release of the Ultra Fine Particle Analyser (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).
Advanced light scattering calculation for non-spherical particles and iterative deconvolution is added to Microtrac’s analysis software.
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.
Driven by a desire to save space and produce a smaller, lighter instrument, Microtrac developed a bent optics bench (Model 7995) to begin the modular approach to particle size instrument design.
A solvent pumping system (Small Volume Recirculator – SVR) was introduced to satisfy the needs of those customers wanting to measure particles suspended in organic solvents. The SVR remained in production until 2007.
The Small Particle Analyser (SPA) with a range of 0.1 to 21 microns was developed. The SPA employed a patented method of differential polarisation of several light wavelengths to measure particles.
A large particle analyser was introduced with a measurement range of 22 to 1200 microns using a linear electronic array.
Dry powder measurement capability was developed and introduced into the Microtrac line.
The Suspended Solids Monitor is introduced to determine the solids content of slurries in process wastewater at water treatment and paper manufacturing plants.
The first commercial laser diffraction analyser, 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.
