Materials Test

Electrical tests on materials investigate their ability to store charge (capacitance) and transfer charge (conductance). Analyzing these parameters can provide valuable information in terms of a material's physical and chemical properties including: Impedance, porosity, tan delta, molecular relaxation, grain boundaries, phase changes, permittivity and modulus, along with many other parameters.

Dielectric analysis is a powerful non-destructive tool for characterising materials; it can provide accurate, repeatable results unavailable by other electrical means. The electrical properties of a material are unique and can be discovered by utilizing the frequency dependence of its constituent components. In addition the study of frequency related phenomena as a function of applied bias or temperature is often essential in the performance testing of materials.

Instrument requirements for useful analysis demand extremely accurate measurement of magnitude and phase, along with reference components and normalization routines to minimize the effects of stray cell and lead capacitances. The Solartron 1260A Frequency Response Analyzer is renowned for its accurate measurement of phase and its wide impedance range, but the development of modern high impedance, low loss materials has meant that further advances in measurement technology have been required. Solartron has specifically designed the 1296A Dielectric Interface to extend the measurement capabilities of impedance analyzers for the materials test market. The introduction of this dielectric test system now allows the user to investigate the frequency response of a material over an extended impedance range (up to 10^14 ohms), and under varying experimental conditions of AC amplitude control, DC bias to 1kV AC or DC, and temperature.

Dielectric Interfaces

1296A Dielectric Interface
Analyzing low conductivity, low loss materials stretches the capabilities of even the best frequency response analyzers (FRAs). Used alone, they lack the sensitivity required for accurate measurements, especially at low frequencies. When used in conjunction with one of our FRAs, the 1296A Dielectric Interface overcomes these issues allowing fast, accurate impedance measurements from 100ohm to 100Tohm with 1 in 65,000,000 resolution.

12962A Sample Holder
The Standard Dielectric Sample Holder (12962A) with 2cm diameter electrode fitted comes complete with presentation case, micrometer and specification sheet for micrometer operating instructions.

Impedance Interfaces

1294A Impedance Interface
Impedance analysis of live samples is now possible with the 1294A Impedance Interface. When coupled with a Solartron frequency response analyzer (FRA), the 1294A Impedance Interface allows measurements that were previously forbidden under strict safety guidelines.

1294A Biological Impedance Interface
Electrical bio-impedance is a well-proven, powerful technique for analysing a wide range of ionic and charge transfer processes in bio-materials. The 1294A Biological Impedance Interface has been designed to meet the present and future needs of bio-material researchers everywhere.

Frequency Response Analyzers/Impedance Analyzers

1260A Impedance/Gain-Phase Analyzer
The 1260A Impedance/Gain-phase Analyzer is without doubt the most powerful, accurate and flexible frequency response analyzer (FRA) available today. Two or four electrode impedance measurements can be performed in stand-alone mode making the 1260A the ideal choice for general materials characterization.

1252A Frequency Response Analyzer
Using the single sine correlation technique (SSC), the 1252A provides precise measurement of gain and phase between any two points in a system. This fully digital technique is used to assess performance of both simple and complex systems - mechanical, electronic and electrochemical.

1255A Frequency Response Analyzer
The 1255A Frequency Response Analyzer is ideally suited to a wide variety of applications in the fields of electronics and the analysis of electrochemical/biological phenomena.

1255B Frequency Response Analyzer
The 1255B Frequency Response Analyzer is one of a range of instruments that will meet your needs today and in the future. This frequency response analyzer is capable of operating in stand-alone mode, suitable for testing amplifiers, filters and switch mode power supplies (SMPS).

1250 Frequency Response Analyzer
The 1250 series of frequency response analyzers (FRAs) provide a range of accurate solutions for the measurement of gain, phase and AC impedance (when coupled with a suitable AC impedance interface).
