Elzone II 5390 Particle Size Analyzer

Widely accepted as a primary particle characterization technique, the electrical sensing zone method is recognized as a highly effective method of counting and sizing a wide variety of organic and inorganic materials.Unlike other measurement techniques, the electrical sensing zone method can analyze samples that have assorted optical properties, densities, colors, and shapes. Micromeritics’ Elzone particle size analyzer uses this powerful particle characterization technique to determine quickly and accurately the size, number, concentration, and mass of finely divided materials. The instrument determines particle size in a range suitable for a wide variety of  industrial, biological, and geological specimens down to 0.4 μm. The Elzone’s high-level of accuracy and resolution, speed, and ease of use make it equally suitable for industry, quality control,and research and development laboratories.

Superior Particle Sizing/Counting Capability in a Small Package

Elzone II Advantages

  • Counts and sizes organic and inorganic materials
  • Suitable for analyzing samples of mixed optical properties, densities, and shapes
  • Higher resolution than with other particle sizing methods
  • Low quantities of sample are analyzed accurately and easily
  • Compact size conserves laboratory bench-space
  • Plot overlays make comparing analysis results with those of product standards or other analysis results easy
  • Extensive statistical analysis and data presentation features included Liquids can be used without knowing viscosity or optical properties
  • A variety of conductive liquids can be used without knowing viscosity or optical properties
  • Does not require previous knowledge of sample properties (density, refractive index)
  • Plot overlays make comparing analysis results with those of product standards or other analysis results easy
  • Optional Confirm 21 CFR Part 11 software assists with compliance to FDA regulations. IQ and OQ services help assure that the system is validated for proper installation, accuracy, and consistent performance.

Ease of Use

  • Automatic start-up, run, and shut down routines
  • Automatic blockage detection and clearing
  • Automated flushing/rinsing
  • Automatic or manual calibration to accommodate different particle types and shapes

New Improved Design

  • No mercury manometer needed to perform concentration analysis
  • A grease-free connect/disconnect mechanism for the orifice tubes
  • A Faraday shield protects detector electronics from external sources of interference
  • Glassware from older Elzone models and certain Coulter Counter models can be used with the new Elzone II.

A Note About 32- and 64-Bit Windows and Micromeritics' Software
Micromeritics products are designed to operate in most Microsoft Windows  environments. However, more current versions of Microsoft Windows, specifically the 64-bit version of Windows 7, lack some of the services once offered by Microsoft. Because of this, Micromeritics applications will not operate with 64-bit operating systems. Micromeritics software applications are directly compatible with 32-bit version operating systems only. In cases where a 64-bit operating system may be corporate-required or essential for running other software programs, Virtual PC software and a 32-bit operating system should be installed on the host computer (64 bit) as a guest operating system. This will allow proper installation and operation of the Micromeritics application.
