  8/16-Channel Potentiostat for High Resolution Data Logger

  The device consists of a combination of an multi-channel potentiostat/converter (BVT Technologies) and an external USB Pico ADC high resolution data logger (Pico Technology).

   

  The data logger can be supplied in two versions: ADC-20 (20 bits, 8 channels) or ADC-24 (24 bits, 16 channels). For detailed specifications, see the attachment at the end of the document. The device allows measurements from up to 8 or from up to 16 independent channels. The basic output signal is a voltage in the range of -2.5 to 2.5 V. All channels are programmable (the output can be concentration, temperature, pressure…).

   

  After connecting the device to a PC with Pico Technology’s Picolog 6 measurement program installed, the voltage [V] can be processed using math channels and directly recorded in real time as temperature, current, resistance, frequency, % and pressure, see measurement example at the end of the document.

   

  For temperature measurement, the device is compatible with resistance thermometers (Ni 1000, Ni 5000, Pt 1000. Power is provided via USB-B, the maximum electrical consumption of the device is 500 mA.

   

  Device Usage

  • Temperature measurement with different temperature sensor (resistance thermometers Ni 1000, ni 5000, Pt 1000)
  • Voltage measurement
  • Conductivity and resistance measurement
  • Amperometry measurement

  Activation furnance for electrochemical sensors

  The activation furnance is a device used for curing individual sensors of the AC1 type. At a defined temperature (up to 1000 °C) depending on the electrode and sensor materials. When the sensor is cured, the surface of the electrodes is cleaned from surface oxides and organic impurities, which results in regeneration of the sensor or its activation. In this way, for example, old sensors with immobilized enzyme layers can be cured for reuse – see example at the end ot the document.

  FC.1ISE.1REF Flow cell for single ion selective electrode with integrated stirring

  The flow cell with integrated stirring and reduced hydrodynamic noise is designed for the determination of single analyte using one miniature ion-selective electrode (ISE) and one miniature reference electrode with a diameter of 6 mm and length of 60 mm.

   

  Rotation speed of integrated stirrer: 10-4000 rmp.

   

  Miniature ion-selective electrodes and reference electrode were designed for integration into the flow cell for determination of Cl-, K+, Ca2+ and Na+ ions.

   

  In flow mode, the system can operate automatically. The speed of the integrated stirrer can also be controlled by applying the corresponding voltage to the motor, connected to a stabilized source.

   

  The flow cell with one selected ISE can be used for:

  • Automatic or semi-automatic measurement of concentration of Cl-, K+, Ca2+ and Na+ ions in various solutions (following prior calibration)
  • For continuous measurement of changes in concentration of Cl-, K+, Ca2+ and Na+ ions.

  EmStat4X

  The EmStat4X delivers high performance in a small footprint. The EmStat4X is a small battery and USB-powered Potentiostat, Galvanostat, and optional Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS).

  The EmStat4X Low Range (LR) version is great for applications that require measuring low currents down to picoamps, like (bio)sensor research. The High Range (HR) version is very suitable for applications that need a maximum current of up to 200 mA. The EmStat4X is controlled with PSTrace for Windows, or you can write your own MethodSCRIPT and control it from any platform or operating system.

   

  More information can be found through the link: https://www.palmsens.com/product/emstat4s/

   

  The EmStat4X LR and HR features include:

  • Fast EIS support: for running fixed-frequency EIS measurements at a very low interval of around 1 ms.
  • Auxiliary Port: for connecting to a MUX8-R2 multiplexer, temperature sensor, pH sensor, stirrer control, triggering and more.
  • iR compensation: to compensate for the iR drop between the Reference electrode and the outside of the double layer of the electrochemical cell.
  • Bluetooth: for a wireless connection to a PC, smartphone or tablet
  • 11.1 Wh battery: for more than 8 hours of continuous measurements (typical with the LR).
  • Small borderless display: showing the state of the battery and connectivity.

  Two versions

  The EmStat4X comes in two different versions:

  • Low Range: for lower currents and potentials (±30 mA / ±3 V applied / ±5 V compliance)
  • High Range: for higher currents and potentials (±200 mA / ±6 V applied / ±8 V compliance)

  Both versions can be configured with optional EIS/FRA up to 200 kHz.
  See specifications for a detailed comparison between the LR and HR.

   

  Always a backup

  The EmStat4X is equipped with 500 MB internal storage memory for storing your measurements as a backup. All internally stored measurements can be browsed and transferred back to the PC easily using the PSTrace software for Windows. Your data is always with your instrument wherever you take it.

   

  Standard included

  A standard EmStat4X includes a rugged carrying case with:

  • EmStat4X LR or HR
  • USB-C cable
  • Cell cable: high quality, double-shielded cable with 2 mm banana connectors for Working, Counter, Reference electrode and Ground, 1 meter long
  • 4 or 5 crocodile clips
  • Dummy Cell

  Also included:

  • PSTrace software for Windows (on USB drive)
  • Manual (hardcopy)
  • Quick Start (hardcopy)
  • Calibration report
