Tri-Laser Particle Characterization
Tri-Laser Particle Characterization
Since the early 1970's Microtrac has a tradition of delivering innovative solutions in Particle Size Analysis through light scattering technology. The S3500 series is a continuation of that tradition. Utilizing the patented Tri-Laser technology, the S3500 provides accurate, reliable and repeatable particle size information for applications ranging from research and development to production, process and quality control. By increasing the number of light sources incident on the material being measured the S3500 Tri-Laser system makes more effective use of photo-detection devices while maintaining maximum stability and alignment of the optical system.

The Microtrac S3500 complies with or exceeds ISO 13320-1 particle size analysis - light diffraction methods. Main features of the S3500 Particle Size Analyzer are:
Resolution. The patented Tri-laser, multi detector optical system delivers unsurpassed resolution over the entire measuring range of the instrument.
Accuracy. As well as Fraunhofer diffraction, Microtrac S3500 utilizes full Mie compensation for spherical particles. It also applies proprietary Modified Mie calculations for non-spherical materials - the majority of real life materials. This feature is unique to Microtrac!
Stability. Optical bench design incorporating fixed detectors and lasers provides a rugged platform for consistently repeatable measurements. The enclosed optical path ensures protection of the optical components leading to little or no operator intervention.
Alignment. Laser alignment is automatic. The overall optical bench stability ensures that auto-alignment is not routinely required.
Range. Measurement capability is from 0.024 to 2800 microns covering most particle size analytical requirements.
Detector Activity. Non-scanning, simultaneous parallel channel integration provides full constant signal accumulation to maximize signal acquisition.
Wet and Dry Measurements. Using a selection of wet and dry sample delivery systems the S3500 can be converted from wet to dry mode in under 2 minutes.
Flexibility. The modular design allows the user selectable configurations based on application requirements. The S3500 system is easily up-gradable to meet future requirements.
Automation. Microtrac FLEX software allows programming, saving and recalling of Standard Operating Procedures (SOP's). This facilitates increased precision in sample preparation and operation through automated, multi sample accessories.
Calibration. Internal uniform light source utilized for testing and calibrating detector segments.
Validation. Full IQ/OQ/PQ support documentation available. The S3500 system meets or exceeds 21 CFR Part 11 security requirements.
