Portable Potentiostat – Galvanostat

Feb 03, 2018 

The potentiostat Model 2559, newest instrument of the potentiostats Amel series, can operate both as potentiostat that galvanostat with 9 current range, from 1 nA to 100 mA fs, and is particularly suited for ultra sensitive measurements, where currents are very low in the pico Ampere order or for field measurements due to its portability.

  1. It can be powered either by the powerline, with an appropriate power supply, or by a 12 V battery
  2. Built in an aluminum container which makes it particularly rugged.
  3. Given its small footprint is easily transportable so it can also be used for measurements in the field.
  4. It can be easily closed in the Faraday cage for very sensitive measures to interference of the power line.
  5. It can be connected to the PC via USB cable and thanks to the new VApeak software, has the ability to make different types of measures for both the electrochemical (batteries, electrode materials, corrosion) that electroanalysis (quantitative analysis for standard additions or with external standard).
  6. Possibility of performing impedance measurements using appropriate external interface specification

Frequency Response Analysis

Feb 03, 2018 

2700Why do we have developed 2700 Z-Pulse for electrochemical studies ?

Because the synergic combination, in a single instrument, of impedance spectroscopy (“Z”) with programmable, high-speed pulse and waveform generation (“pulse”) will open new and exciting possibility in electrochemistry.

Everything can be done with 2700/Z-Pulse and few mouse clicks: from battery characterization under real environmental conditions to complex pulse sequences for thin-film formation, from impedance spectra under potentiostatic or galvanostatic regime to fast voltammetry.

The new 2700 module with Z-Pulse software from AMEL connects  with the 255X series of AMEL Potentiostats as well as with most manual instruments.

Z-Pulse software is a very simple and friendly approach to modern electrochemistry. In fact, the 5-MHz sampling frequency will allow μs time resolution in pulse sequences and sinewave FRA up to 1 MHz.

All data can be saved in CVS format for further use.

ThinCorr

Feb 03, 2018 

thincorrThinCorr: think local, be versatile

In many metal corruption analysis scenarios, extracting small samples of material from large components and bringing to the laboratory is simply impossible. In such situations measurements on site become the only option. Since the advent of very precise miniaturized electrochemical cells, Amel has developed his own on-site system, called ThinCorr, designed to get the same performance of a complete laboratory set, wherever you need.

A unique bundle for a double convenience

ThinCorr includes a miniaturized cell – EC Minicell – designed to perform localized electrochemical investigations on surface areas of the order of mm2. thincorrThe test component is the 2556 Amel Portable Potentiostat, designed on purpose to pair the EC MiniCell features.

Nice ’n easy to work with

The miniaturized cell has been designed in a way that the electrolyte can flow in proximity of the working electrode, avoiding concentration gradients and the corresponding polarizations. Within the body of the EC Minicell there are channels that allow the flow of the electrolyte and that contain a counter electrode and a reference electrode. At the nozzle of the cell there is a gasket that delimits the area of the working electrode, when the EC Minicell is pressed against a metallic surface. ThinCorr system is driven by a proprietary software via personal laptop.

Performance you’ll simply adore

  • EC Minicell is a miniaturized, resistant, handy, and complete electrochemical cell suitable for localized electrochemical measurements.
  • Measurements are carried out with the electrolytic solution flowing from the reservoir to the WE and then back to the reservoir in a closed circuit loop. Fluid flow favors the removal of reaction products from the WE region.
  • There are not specific constraints on the types of electrochemical tests that can be performed, e.g. cyclic voltammetry, coulometry, and localized electrodeposition, thanks to the 2556 dedicated Potentiostat.
  • ThinCorr is a handy, trustable and versatile instrument for a variety of electrochemical measurements.

Galvanostat for electrolysis

Jul 23, 2012 

Better quality, improved performance

2547 photoThe introduction of the AMEL Model 2547 Galvanostat completes the new line of AMEL 2000 series in struments.  The Model 2547 Galvanostat was designed to perform electrogravimetric analysis for the determination of metal content in solution. The instrument is equipped with two displays to monitor the power and potential of the cell.

A third display is used to measure the time of polarization of the cell. The counter electrode at the center can run up to a maximum of 100 revolutions per minute to provide the required stirring to maintain a highly uniform metal deposition on the platinum gauze cathode. Thanks to the specific electronic circuitry, the current set remains constant, even with changes of the conductivity of the solution. The circuits are designed to work continuously and are well-protected against short circuits. The cabinet is ruggedly constructed of epoxy-painted steel and a polycarbonate film panel.

Temperature – pH Meters

Jan 26, 2012 

The HD2105.1 and HD2105.2

are portable instruments with a large LCD display. They measure the pH and the redox potential (ORP) in mV. They measure the temperature using Pt100 or Pt1000 immersion, penetration or contact probes. The electrode calibration can be carried out on one, two or three points and the calibration sequence can be chosen from a list of 13 buffers. The temperature probes are equipped with an automatic recognition module and factory calibration data are stored inside.

The HD2105.2 is a datalogger. It stored up to 34,000 pH and temperature samples which can be transferred to a PC from the instrument connected via the multi-standard RS232C serial port and USB 2.0. The storing interval, printing, and baud rate can be configured using the menu.

The HD2105.1 and HD2105.2 models are fitted with an RS232C serial port and can transfer the acquired measurements in real time to a PC or to a portable printer. The Max, Min and Avg function calculate the maximum, minimum or average values.
Other functions include: the relative measurement REL, the Auto-HOLD function, and the automatic turning off that can also be excluded.

The instruments have IP67 protection degree.

Polarisation Cell for Disks or Flat Specimens

Oct 17, 2011 

599Suited for measurements on coated specimens in flowing or stirred solutions.

The design of this cell allows the solution to be vigorously stirred under the sample with the purpose to remove diffusion layer in research concerned with coated or painted samples.

Main body is a large glass container on which a cap with 4 ground joints is situated.

The sample holder is a large cylinder of acrylic resin with a screwable cap retaining the specimen through a calibrated O-RING which determines the exposed area.

Two Model 805/SPG/12J platinum electrodes grant enough field symmetry.

A Luggin capillary couples the reference electrode at the shortest distance. Replacement of specimen does not require exhausting of the cell. The Model 291/MAST stirrer is placed at middle bottom of the container thus granting reproducible stirring.

597The upper cap is fitted with 4 ground joints for electrodes or accessories.

Disks or flat specimens are locked between main body and a “matching section” the purpose of which is to determine the area of specimen under attack.

Tight-ness is granted by calibrated O-RINGS.

Counter electrode is introduced into central neck to face the specimen, while a Luggin capillary couples the reference electrode at the shortest distance from the specimen.

Gas bubbling or electrolyte circulation is available through inlet-outlet.
