C
Procedure to validate the characterisation data. (en) +
A characterisation experiment is the process by which a material's structure and properties are probed and measured. It is a fundamental process in the field of materials science, without which no scientific understanding of engineering materials could be ascertained. (en) +
Whatever hardware is used during the characterisation process. (en) +
D
Physical device (or the chain of devices) that is used to measure, quantify and store the signal after its interaction with the sample. (en) +
C
The measurement process associates raw data to the sample through a probe and a detector. (en) +
A characterisation protocol is defined whenever it is desirable to standardize a laboratory method to ensure successful replication of results by others in the same laboratory or by other laboratories. (en) +
Set of one or more measuring instruments ('CharacterisationInstruments') and often other components and devices, including any sample holder, reagent and supply, assembled and adapted to give information used to generate measured values ('MeasuredQuantityProperty') within specified intervals for quantities of specified kinds. (en) +
The description of the overall characterisation technique. It can be composed of different steps (e.g. sample preparation, calibration, measurement, post-processing). (en) +
A characterisation procedure that has at least two characterisation tasks as proper parts. (en) +
The sample after having been subjected to a characterization process. (en) +
In chemical analysis, chromatography is a laboratory technique for the separation of a mixture into its components. (en) +
Amperometry in which the current is measured as a function of time after a change in the applied potential. If the potential step is from a potential at which no current flows (i.e., at which the oxidation or reduction of the electrochemically active species does not take place) to one at which the current is limited by diffusion (see diffusion-limited current), the current obeys the Cottrell equation. (en) +
Direct coulometry at controlled potential in which the electric charge passed after the application of a potential step perturbation is measured as a function of time (Q-t curve). Chronocoulometry provides the same information that is provided by chronoamperometry, since it is based on the integration of the I-t curve. Nevertheless, chronocoulometry offers important experimental advantages, such as (i) the measured signal usually increases with time and hence the later parts of the transient can be detected more accurately, (ii) a better signal-to-noise ratio can be achieved, and (iii) other contributions to overall charge passed as a function of time can be discriminated from those due to the diffusion of electroactive substances. (en) +
Potentiometry in which the potential is measured with time following a change in applied current. The change in applied current is usually a step, but cyclic current reversals or linearly increasing currents are also used. (en) +
P
Method of electroanalytical chemistry based on measurement of an electrode potential. Potentiometric methods are used to measure the electrochemical potentials of a metallic structure in a given environment. For measurements using ion-selective electrodes, the measurement is made under equilibrium conditions what means that the macroscopic electric current is zero and the concentrations of all species are uniform throughout the solution. The indicator electrode is in direct contact with the analyte solution, whereas the reference electrode is usually separated from the analyte solution by a salt bridge. The potential difference between the indicator and reference electrodes is normally directly proportional to the logarithm of the activity (concentration) of the analyte in the solution (Nernst equation). See also ion selective electrode. (en) +
C
Compression tests characterize material and product strength and stiffness under applied crushing loads. These tests are typically conducted by applying compressive pressure to a test specimen using platens or specialized fixtures with a testing machine that produces compressive loads. (en) +
Titration in which the electric conductivity of a solution is measured as a function of the amount of titrant added. The equivalence-point is obtained as the intersection of linear parts of the conductance G, versus titrant volume V, curve. The method can be used for deeply coloured or turbid solutions. Acid-base and precipitation reactions are most frequently used. The method is based on replacing an ionic species of the analyte with another species, cor- responding to the titrant or the product with significantly different conductance. (en) +
Confocal microscopy, most frequently confocal laser scanning microscopy (CLSM) or laser scanning confocal microscopy (LSCM), is an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation. (en) +
Measurement principle in which the electric conductivity of a solution is measured. The conductivity of a solution depends on the concentration and nature of ions present. (en) +
Titration in which the titrant is generated electrochemically, either by constant current or at constant potential. The titrant reacts stoichiometrically with the analyte, the amount of which is calculated using Faraday’s laws of electrolysis from the electric charge required to reach the end-point. Coulometric titrations are usually carried out in convective mass transfer mode using a large surface working electrode. The reference and auxiliary electrodes are located in sepa- rate compartments. A basic requirement is a 100 % current efficiency of titrant generation at the working electrode. End-point detection can be accomplished with potentiometry, amperometry, biamperometry, bipotentiometry, photometry, or by using a visual indicator. The main advantages are that titration is possible with less stable titrants, the standardi- zation of titrant is not necessary, the volume of the test solution is not changed, and the method is easily automated.
