The 1260A Impedance/Gain-Phase Analyzer is - without doubt - the most powerful, accurate and flexible Impedance Analyzer available today. In daily use by leading researchers wherever measurement integrity and experimental reliability are of paramount importance, the 1260A’s solid reputation is frequently endorsed in published research papers in fields such as:
Battery research and fuel cells
Ceramics / composites
Electronic component development
Huge frequency range:
Spanning 10 μHz to 32 MHz with 0.015 ppm resolution, 1260A provides excellent coverage for virtually all chemical and molecular mechanisms - all in a single instrument.
With an accuracy of 0.1%, 0.1°, measurements can be made with complete confidence, and even the most subtle changes in sample behavior detected and quantized.
Noise free analysis:
1260A uses Solartron Analytical’s patented single-sine correlation technique, which inherently removes the noise and harmonic distortion which plagues lesser instruments.
Frequency resolution: 1 in 65 million (0.015 ppm)
0.1%, 0.1° accuracy – unsurpassed by any similar instrument
Resolution to 0.001 dB, 0.01° - capturing every detail
Measures impedances >100 MΩ
2-, 3- and 4-terminal measurement configurations
Polarization voltage up to ±40.95 V
Renowned ZPlot software package simplifies experiments and optimizes throughput
For even higher impedance measurements to 100 TΩ, add 1296A
When combined with other products from Solartron Analytical’s range, including well-proven application software, 1260A can form the heart of an advanced electrochemical and materials measurement system, to provide superb accuracy, flexibility and reliability - even for the most complex research problems.
All liquids and solids are able to pass current when a voltage is applied. If a variable (AC) voltage is applied to the material, the ratio of voltage to current is known as the impedance. The measured impedance varies with the frequency of the applied voltage in a way that is related to the properties of the liquid or solid. This may be due to the physical structure of the material, to chemical processes within it or a combination of both.
The advantages of impedance measurement over other techniques include:
Rapid acquisition of data
Accurate, repeatable measurements
Highly adaptable to a wide variety of different applications.
Ability to differentiate effects due to electrodes, diffusion, mass/charge transfer by analysis over different frequency ranges
