THE NEW INSTRUMENT FOR FISH-SCALE RISK ASSESSMENT 

THE NEW INSTRUMENT FOR ELECTROCHEMICAL HYDROGEN PERMEATION

HELIOS 2 PERMEATION is an innovative laboratory instrument that can measure both permeability and hydrogen diffusion coefficient through metallic steel sheets. HELIOS 2 PERMEATION is suitable for evaluating the effectiveness of barrier coatings for hydrogen flux, which is essential for identifying materials in the new hydrogen economy.

The test is carried out referring to ASTM G148 and ISO 17081 Standards.

The traditional equipment used for this type of experiments is the so-called Devanathan-Stachurski double cell, HELIOS 2 PERMEATION replaces the anodic cell with a probe which contains the hydrogen gas sensor.

HELIOS 2 PERMEATION does not require the passivation preparation of the anodic side of the sample and it can assess also diffusivity and hydrogen flux through the coated samples.

Once acquired, the signal that depends on the hydrogen flux through the examined test sample, is processed by proper mathematical codes (by means of a dedicated panel PC) and hydrogen diffusion parameters are evaluated.

HELIOS 2 PERMEATION is a completely automated instrument!

Letomec offers customized instruments and consultancy to define optimal hydrogen charging conditions (current density, electrochemical solution, re-circulation of the test solution, air circulation, etc.), set-up, which depends on the hydrogen charging side that can be electrochemical or gaseous.

The HELIOS Platform including HELIOS 2 PERMEATION is coverd by the Patent N. EP 2912452 B1.

The instrument can be customized according to the user's need.

THE NEW INSTRUMENT FOR HYDROGEN ACTIVITY EVALUATION DURING GALVANIC DEPOSITION

HELIOS 2 GALVANIC is an innovative laboratory instrument that can be used to evaluate the hydrogen adsorption during the galvanic processes.

HELIOS 2 GALVANIC can also be used as a laboratory equipment to compare the hydrogen activity of different galvanic baths. The test method is based on the elaboration of the permeation curve obtained for ARMCO Pure Iron sheets using the process conditions applied in galvanic industry (current density, test solution, temperature, liquid circulation, air insufflation, etc.).

Moreover the Instrument can be also used to optimize inhibitors concentration, pickling temperature, help galvanic bath formulators…

Once acquired the signal that depends on the hydrogen flux through the examined test sample, is processed by proper mathematical codes (by means of a dedicated panel PC) and hydrogen bath activity is evaluated.

HELIOS 2 GALV is a completely automated instrument!

Letomec offers customized instruments and consultancy to define optimal hydrogen charging conditions (current density, electrochemical solution, re-circulation of the test solution, air circulation, etc.).

The HELIOS Platform including HELIOS 2 GALVANIC is coverd by the Patent N. EP 2912452 B1.
