An advanced, comprehensive solution for the electrical characterization of materials

A modern materials science lab faces challenging measurements every day, and impedance spectroscopy is a primary tool in materials research enabling the characterization of the electrical properties of materials.

With a wide frequency range (10 µHz – 35 MHz) and high-levels of accuracy (0.1% amplitude, 0.05% phase) the BioLogic MTZ-35 impedance analyzer has been designed to tackle even the most difficult measurements required by materials science.

The MTZ-35 is the key instrument in integrated solutions for the electrical characterization of materials. These solutions, dedicated to wide-ranging applications and temperature ranges, consist of the MTZ-35 impedance analyzer, a temperature control unit, a sample holder and MT-lab software. The MT-Lab interface allows the control of many temperature control systems (HTF-1100 furnace, ITS, etc.) over a wide temperature range (from -40 to 1100°C).  It also allows impedance measurement and the modeling of EIS data with equivalent circuits. Many sample holders (CESH, HTSH-1100, HTCC) covering various materials types (polymers, ceramics, composites, ionic liquids, gels, etc) are compatible with the MTZ-35.

 

An intuitive and comprehensive software

MT-Lab® is an intuitive and user-friendly software dedicated to the control of Bio-Logic’s impedance analyzer, the acquisition of the impedance data and the temperature. It also allows the control of many temperature control units:

  • High-temperature furnace (HTF-1100)
  • Intermediate Temperature System (ITS)
  • Temperature control systems using Eurotherm 22xx and 35xx series controllers…

Specifications

  • Generator

    • Frequency Range: 10 μHz to 35 MHz
      Voltage range DC: ±100 μV to ±10 V
      Voltage range AC: 100 μV to 10 V

    Measurement Ranges

    • Inductance 10 nH to 10 kH
    • Capacitance 1 pF to 1000 μF
    • Resistance 1 mΩ to 500 MΩ
    • Basic Accuracy 0.1%

I receive many cell cables with MTZ-35 which one should I use?

The MTZ-35 is provided with two sets of cables:

  • A set of four cables (x1 m) for four-point measurement dedicated for impedance measurements on low impedance samples (lower than 1 Ω)
  • A set of three cables with a Tee connector for two-point measurement for impedance measurements on intermediate and high impedance samples. More details can be found in the TN#05

My MTZ-35 does not beep when I turn it on? How can I proceed?

If the power led is off when you switch on the MTZ-35, check the fuses located on the rear panel of the instrument. If a fuse is blown replace it with a new one rated at 3.15A. You can use the two 2A rapid fuses provided at the purchase of the MTZ-35.

How do I check the accuracy of results given by the MTZ-35?

Any instrument is prone to a drift in its accuracy with time and use. In order to check the accuracy of the MTZ-35, use a high accuracy resistor or capacitor and check the measured resistance/capacitance with their corresponding nominal resistance/capacitance.

Which communication port should I connect the MTZ-35 to?

When you install MT-Lab® software the driver of the MTZ-35 is also installed and two virtual communication ports are generated. To access to these communication ports go to “Control Panel”>”External Devices”> “Ports(COM & LPT)”. You can see two virtual communication ports “USB serial port (COM N)” and “USB serial port (COM N+1)”. Select the one with the high order (COM N+1).

I performed a measurement on a capacitor with a nominal capacitance 100 pF I got 320 pF capacitance value. Do I need to calibrate my MTZ-35?

The measured capacitance should coincide with the nominal capacitance. your measurement seems to be performed without compensation. Perform open-circuit and short circuit compensation and then perform impedance measurement on the capacitor. More details can be found in the TN#01 and AN#04
