Model 1260A Impedance / Gain-Phase Analyzer
The model 1260A Impedance/Gain-Phase Analyzer is - without doubt
- the most powerful, accurate and flexible Frequency Response
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:
- Corrosion studies
- Battery research and fuel cells
- Solar cells
- LCD's
- Bio-materials
- Ceramics / composites
- Electronic component development
- Civil engineering
One of Solartron Analytical’s extensive range of precision
products designed to provide cost effective solutions for DC and AC
analysis in electrochemical and materials research, the 1260A offers
an outstanding measurement specification for impedance spectroscopy.
Wide frequency range
Spanning 10µHz to 32MHz with 0.015ppm resolution, the 1260A
provides excellent coverage for virtually all chemical and molecular
mechanisms - all in a single instrument.
Unbeatable accuracy
With an accuracy of 0.1%, 0.1º, measurements can be made with
complete confidence, and even the most subtle changes in sample
behavior detected and quantized
Noise free analysis
The 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 (0.015ppm)
- 0.1%, 0.1º accuracy - unsurpassed by any similar instrument
- Resolution to 0.001dB, 0.01º - capturing every detail
- Measures impedances >100MΩ
- 2-, 3- and 4-terminal measurement configurations
- Polarization voltage up to ±40.95V
- Compatible with the renowned ZPlot software package to
simplify experiments and optimize throughput.
Systems
When combined with other products from Solartron Analytical’s
range, including well-proven application software (ZPlot
or SMaRT), the 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.
Impedance measurement
Virtually every liquid and solid is able to pass current when a
voltage is applied to it. 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
- Non-destructive
- 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
- Equivalent circuit/modeling
