  • 系統概要:
    • 分析低導電率、低損耗材料,超出了即使是最佳阻抗分析儀的性能範疇,單獨使用時,它們缺少精準測量所需要的靈敏度,尤其是在低頻率時。Solartron 1296A介電質介面測試系統,克服了這些限制,在頻率範圍10μHz~10MHz,提供您快速精準及可重複的阻抗測量,從而獲得對於廣泛材料特性的深刻理解,包括聚合物、陶瓷、離子導體、介電質、壓電/鐵電材料、顯示材料…等。
    • 結合操作簡單的軟體,以1296A為基礎的系統,可以負責執行實驗方法,讓您專注於測試結果的解讀。
    • 1296A搭配Solartron知名的1260A或1255A頻率響應分析儀,可增強其性能、解決測試介電材料遇到的超小電流及電容位準問題,而能執行以下測量:
      • 阻抗測量:超過100TΩ (1014Ω)。
      • 精準的Tan δ測量:降至<10-4
      • 頻率範圍:10 μHz~10 MHz。
      • AC信號及DC偏壓電壓達到10,000V(搭配外部電源供應器或放大器),適於介電崩潰和線性研究。
    • 1296A內建高度精準的參考電容器,以用於樣本/參考測試,或者,也可選擇採用一個外部參考,提供了無比的靈活性,能滿足幾乎每一種測量需求。
    • 測量軟體支援溫度及DC控制器,可進一步擴大了材料分析的範圍。
  • 介電質的定義:
    • 許多材料都具有低電導(高阻抗)和低損耗的特性,它們通常稱為介電質,儘管有許多通常不被視為介電質的材料也表現出這些性質。
    • 有一種常用於分析此種材料的方法是阻抗頻譜 - 測量某個頻率範圍上的電阻抗。阻抗與材料的導電率及電容有關,而這些參數,反過來,又可能與材料的分子活性相關。
    • 當施加交流電壓到介電質樣本上時,有些能量由電容儲存,有些因電阻效應而逸散。
    • 在樣本內因此導致的電流,將表現出一種相位滯後δ。在材料研究中,電容效應被稱為介電常數ε’,電阻效應被稱為介電損耗ε”,Tan δ,逸散因數等於ε”/ε’。
    • 在ε”極小而ε’極大的材料中,假如要執行一個精準的測量,Tan δ的解析度,就變得很關鍵。1296A藉由對自動取代樣本的精密電容器進行的一次參考測量,克服了此點問題,並進行第二次針對樣本本身的測量,再利用這2次測量結果,導出材料的一個精準的介電常數測量值 – 實際上,第一次測量是用於排除外來電容的影響。

  • System Overview:
    • Analyzing low conductivity, low loss materials stretches the capabilities of even the best impedance analyzers. Used alone, they lack the sensitivity required for accurate measurements, especially at low frequencies.
    • The 1296A Dielectric Interface overcomes these limitations to give you fast, accurate and repeatable impedance measurements over 12 decades of frequency, yielding valuable insights into the characteristics of a wide range of materials, including polymers, ceramics, ion conductors, dielectrics, piezo/ferroelectrics, display materials etc.
    • Coupled with easy-to-use software, a 1296A-based system takes care of experimental technique and lets you concentrate on interpreting the results.
    • The 1296A enhances the capabilities of Solartron Analytical’s renowned 1260A and 1255A FRAs to cope with ultra-low current and capacitance levels experienced in testing dielectric materials, enabling:
      • Impedance measurements to exceed 100 TΩ (1014Ω)
      • Accurate tan delta measurements down to <10-4
      • Frequency range from 10 μHz up to 10 MHz
      • AC signal and DC bias voltages up to 10,000 V (with external psu or amplifier) for dielectric breakdown and linearity studies
    • Highly accurate reference capacitors are built in to 1296A for sample/reference testing, or you can choose to use an external reference, offering unrivaled flexibility to meet almost every measurement need. Support for temperature and DC controllers is integral to the measurement software, further increasing the scope for materials analysis.
  • Defining Dielectrics:
    • Many materials have the properties of low conductance (high impedance) and low loss. They are often referred to as dielectrics, although many materials not normally considered as dielectrics exhibit these properties.
    • One popular technique for analyzing such materials is Impedance Spectroscopy - measuring the electrical impedance over a range of frequencies. The impedance is related to the conductivity and capacitance of the material, and these parameters can in turn be related to the molecular activity of the material.
    • When an alternating voltage is applied to a dielectric sample, some energy is stored by the capacitance, and some is dissipated by the resistance effects.
    • The resulting current in the sample will exhibit a phase lag, δ. In materials research, the capacitance effect is known as the permittivity (or dielectric constant) ε’, and the resistive effect as dielectric loss, ε”. Tan δ, the dissipation factor equals ε”/ε’.
    • In materials where ε” is very small and ε’ large, the resolution of tan δ becomes critical if an accurate measurement is to be made. The 1296A overcomes this by taking a reference measurement on precision capacitors which are automatically substituted for the sample; a second measurement is made, this time on the sample itself. The two results are used to derive an accurate measurement of the permittivity of the material - in effect, the first measurement is used to eliminate the effects of extraneous capacitance.
