High Speed and High Efficiency Dynamic Light Scattering

Looking for Nanoparticle size analysis

Having trouble with submicron particle sizing?

New England Sales specializes in submicron and nano particle measurement and analysis systems.  We represent Microtrac, Inc. who has been a pioneer in light scattering particle size technology for 30 years, and introduced the Ultrafine Particle Analyzer in 1990. The newly enhanced and designed Nanotrac, features faster measurements (up to 20 times faster), smaller particle size capability (to 0.8 nm), higher precision, higher accuracy and advanced software capabilities all in one small, robust dynamic light scattering instrument having no moving components.

Features of the Nanotract Dynamic Light Scattering System:

• Rapid analysis – as fast as 15-30 seconds in most cases
• Design – No moving parts and simple design means that that there are no parts to wear nor be replaced
• Chemical compatibility — Compatible with all organic solvents
• ISO 13321 — Complies with this ISO standard on particle size measurements for Dynamic Light Scattering
• Brownian motion analysis — Advanced power spectrum analysis of Doppler shifts by the Controlled Reference Method, patented by Microtrac, Inc.
• Temperature control – Precise temperature monitoring and compensation eliminates need for temperature control baths or devices
• High concentrations — This capability can eliminate concern of dilution, a cause of agglomeration or dissolution
• Low concentrations – As low as 0.1 ppm @200nm polystyrene
• Operation simplicity – No advance knowledge of particle distribution required — just add sample and measure
• Security — Software compatible with FDA 21 CFR Part 11 for computer and software security
• Colored materials — Avoids multiple wavelength absorption issues
• Physical size — Smallest dynamic light scattering footprint available in particle size industry. Also available in a remote probe model for external (“Dip ‘N’ Run”) measurement or for in line measurement
• Accuracy – Mie scattering calculations for spherical particles and proprietary modified Mie calculations for nonspherical particles. Only Microtrac offers this enhanced accuracy for non-spherical particles — the majority of real world materials
• Range – Measurement capability from 0.0008 to 6.5 microns satisfies most nanotechnology applications
• Calibration – First principle optical physics avoids the need for calibration – verification test kits are available. Alignment is never needed
• FDA Validation – Full documentation and personal customer support
• Small sample size – Less than 3 ml per sample standard cell, or as small as 0.1 ml with small cell option
• Traceability — Particle size measurement traceable to NIST standards
• Cost effective long term operation – The probe design avoids cost of expendable cuvettes and pre-cleaning requirements; A background measurement avoids need for ultra clean diluents
• Applications — Organic polymers (latex polymers and others), nanometals and other nanoinorganics, proteins, lipoproteins, DNA, and RNA
• Data presentation — Accurately report narrow, monomodal, multimodal, and broad range distributions in a variety of statistical formats without the need to select special calculation algorithms
• Resolution – Measures monomodal, multimodal, broad and narrow distributions automatically without pre-selecting special programs
• Consistency – Features afixed detector and laser design, which delivers repeatability and linearity. High concentration capability avoids agglomeration or dissolution of particles during dilution
• Flexibility — The modular design allows selectable configurations based on your application and can be expanded to meet future needs at any time
• Electronics — Advanced, high efficiency electronics for accurate particle size measurements
• Upgrades — Prior UPA models can be upgraded depending upon present hardware and software
• Power demand and safety — Low power laser provides electric and laser irradiation safety
• Versatility – Versions for the lab bench, on-line or even in-line for process control applications
• Reliability — Robust, rugged design assures reliable use for many years into the future.
