Description

PStouch is an app for Android devices that can be used with all PalmSens and EmStat potentiostats. PStouch communicates with your potentiostat directly via USB or wirelessly using the PalmSens Bluetooth dongle. A Bluetooth dongle is available for your older and your newest PalmSens.

Features

PStouch contains the following features:

  • Setting up and running measurements
  • Loading and saving measured curves
  • Analysing and manipulating peaks
  • Sharing data directly via e-mail, Dropbox, or any other file sharing service
  • Support for PalmSens accessories such as a multiplexer, stirrer or bipot

All method and curve files are fully compatible with our PSTrace software for Windows. The power provided by the USB is sufficient to operate an EmStat. This way it is possible to carry an electrochemical work place with you that weights 300 g (Samsung Galaxy S4, EmStat3, sensor cable, USB cable).

Available techniques

The following techniques are supported by PStouch.

Voltammetric techniques:

  • Linear sweep voltammetry (LSV)
  • Differential pulse voltammetry (DPV)
  • Square wave voltammetry (SWV)
  • Normal pulse voltammetry (NPV)
  • AC voltammetry (ACV)
  • Cyclic voltammetry (CV)
  • Chronopotentiometric stripping (SCP/PSA)

Technique as a function of time:

  • Chronoamperometry (CA)
  • Pulsed amperometric detection (PAD)
  • Multiple pulse amperometry (MPAD)
  • Fast amperometry (FAM)
  • Potentiometry (POT)
  • Open circuit porentiometry (OCP)
  • Multistep amperometry (MA)
  • Multistep potentiometry (MP)

Impedance spectroscopy / EIS

  • Potential scan
  • Time scan
  • Scans can be made at a fixed frequency or with a frequency scan.
  • Fixed potential

 

Sharing measurement results

Perform measurements in the field and share data immediately with colleagues in the lab. Data can be stored locally, of course, but PStouch offers share functions to send your data with your email applications to any place you need it. Also the dropbox app, google drive or any other app supporting sharing functionalities is supported by PStouch. So directly after your measurement, your data is safe and backed up before you are back in the lab.

Data processing

PStouch offers you the basic tools to analyse your data. You can look at single points or have automatic peak detection. Detected peaks are analysed for their potential, peak current, peak height, width and area. A survey of the parameters for all peaks is available with one touch.

PStouch saves the data in same format as our windows software PSTrace does. Accordingly all data recorded with PStouch can be further processed with all the functions of PSTrace. So even more advanced analysis will be handled with ease. Take a measurement, share it, your colleagues import it to PSTrace and send the results back to you.

Connection Options

The PStouch app can be used with the following instruments from PalmSens BV:

Instrument Connection
PalmSens2 USB requires original USB cable from PalmSens BV.
Bluetooth requires small factory modification.
PalmSens3 Bluetooth by means of PalmSens3 Bluetooth extension.
EmStat Blue EmStat Blue has an on-board Bluetooth radio.
EmStat1
EmStat2
EmStat3
EmStat3+

 = Connection is available via Bluetooth dongle
 = Connection is available via USB On-The-Go cable

Tablet / Phone Requirements:

  • Android version 4.0 (Ice Cream Sandwich) or higher
  • USB On-The-Go compatible or Bluetooth

 

 

Connecting via USB

In order to connect via the USB port of an instrument, an On-The-Go cable or OTG cable is required.

OTG cable

This cable can be found in virtually any electronics store and is available via PalmSens BV. As soon as a connection is made with an Android device a message will appear asking to allow the connection. The app will connect automatically if the connection to the EmStat or PalmSens is allowed.

Connecting via Bluetooth

For both PalmSens2 (old model) and PalmSens3 a Bluetooth dongle is available:

Bluetooth dongle for PalmSens3

Each PalmSens3 can be expanded with a Bluetooth dongle, available at PalmSens BV. The PalmSens2 needs a small modification before it is able to work with a Bluetooth dongle.
