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:
Huge frequency range
Spanning 10μHz to 32MHz with 0.015ppm resolution, 1260 provides excellent coverage for virtually all chemical and molecular mechanisms – all in a single instrument.
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
1260 uses Solartron Analytical’s patented single-sine correlation technique, which inherently removes the noise and harmonic distortion which plagues lesser instruments.
When combined with other products from Solartron Analytical’s range, including well-proven application software, 1260 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.
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.
