MultiPalmSens4

Multi-channel Potentiostat / Galvanostat / Impedance Analyzer

  • 4 to 10 channels available in different configurations
  • FRA / EIS: 10 μHz up to  1 MHz
  • 9 current ranges: 100 pA to 10 mA
  • potential range: ±5 V or  ±10 V

 

The MultiPalmSens4 is a flexible multi-channel potentiostat, galvanostat and impedance analyzer which you can fully tailor to your requirements and budget. The MultiTrace software allows for using each channel individually or simultaneously or running a sequence of automated tasks on each channel. Each channel provides an additional auxiliary port for controlling peripherals or monitoring temperature or other analog signals.

Configure your ideal multi-channel potentiostat

Each channel can be configured with:

  • ±5 V or ±10 V maximum potential range
  • EIS/FRA with maximum frequency of 100 kHz or 1 MHz
  • Bipotentiostat module for second WE
  • iR-Compensation
  • Galvanic isolation

 

Always a backup

Every channel of the MultiPalmSens4 is equipped with 8 GB storage space. This means all your measurements* can automatically be saved on-board as backup.
Measurements can be browsed and transferred to the PC easily using the MultiTrace software for Windows.

 

Synchronizing channels in Synched mode

By enabling synchronization of channels and adjusting the setup of your cables, you can use the MultiPalmSens4 as a polypotentiostat. This means you can use multiple working electrodes, one counter and one reference electrode in the same cell at the same time. Your working electrodes all perform the same measurement.

    Connection options

    The most selected connection option uses two double shielded D-Sub cables ending in 2 mm banana plugs. As alternatives we can provide a PCB with screw terminals, D-Sub cable ending in ferrules or Screen Printed Electrode Adapter. Each of these cables can be connected to 4 channels, if all 8 channels are used, two cables are needed.

  • EmStatMUX8-R2

    USB powered potentiostat with integrated multiplexer

    • potentiostat with integrated 8 channel multiplexer
    • potential range: ± 3V or ± 4V
    • compliance voltage: ± 5V or ± 8V
    • current ranges:  1 nA – 100 mA
    • maximum current: ± 100 mA

     

    With the EmStat3MUX8-R2 you can connect arrays or other setups made of up to eight working electrodes in two or three electrode cell types. If more channels are required, one or more MUX-R2 can be stacked to the EmStatMUX8-R2 for a total of up to 128 channels.

     

    The potentiostat is controlled as well as powered by USB and is used with PSTrace. The MUX8-R2 can sample different cells at a rate of 25 ms/cell. Usually a method needs to be finished to switch the cell but the fast sampling per cell makes it possible to measure time depending techniques, e.g. chronoamperometry, practically simultaneously. Via the script window of PSTrace it is also possible to perform a different experiment on each of the channels sequentially.

    Cell connections

    There are four ways to connect your sensor. These sensor connections are quoted separately. 

    • Option A: Double shielded sensor cables with 2 mm banana connectors. The 2 mm banana connectors are compatible with standard croc clips (they will be included in the quotation as optional).
    • Option B: High-density cable that terminates in ferrules
    • Option C: Connection (Screw) Terminal  to assemble your own wires.
    • Option D: Screen Printed Electrode Connector

    Each of these connection options can be used to connect 4 channels. When you add the EmStatMUX8 in the quotation basket we will make sure to include two units of the selected connection option so you can connect all 8 channels to the electrochemical cells.

  • 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.
