O
Optical microscopy is a technique used to closely view a sample through the magnification of a lens with visible light. (en) +
Outlier removal refers to the process of identifying and eliminating anomalous data points that deviate significantly from the overall pattern of a dataset. These outliers are generally considered to be observations that are unusually distant from other values and can potentially distort the results of analyses. (en) +
P
Photoluminescence spectroscopy is a widely used technique for characterisation of the optical and electronic properties of semiconductors and molecules. (en) +
Polishing is a machining process to achieve a smooth surface of the Sample, which uses abrasive compounds with smal particles that are embedded in a pad or wheel. (en) +
Mathematical model used to process data. (en) +
Two-step electrochemical measurement in which 1) material is accumulated at an electrode and 2) the material is removed by chemical reaction or electrochemically at constant current with measurement of electrode potential. Historically for the analysis of metal ions, mercury ions were added to the test solution to form a mercury amalgam when reduced. Alternatively, an HMDE or MFE was used and the oxidizing agent added after amalgam formation. However, the toxicity of mercury and its compounds have all but precluded the present-day use of mercury. The accumulation is similar to that used in stripping voltammetry. The stripping potentiogram shows staircase curves of potential as a function of time. Frequently, the first derivative is displayed (dE/dt=f(t)), as this produces peak-shaped signals. The time between transitions (peaks) is proportional to the concentration of analyte in the test solution. The time between changes in potential in step 2 is related to the concentration of analyte in the solution. (en) +
The sample after a preparation process. (en) +
Data resulting of a pre-processing of raw data, applying corrections to normalize/harmonize, in order to prepare them for the post-processing. (en) +
Process representing the interaction between the Probe and the Sample (with a certain Interaction Volume) which generates a Signal. (en) +
S
Result (effect) of the interaction between the sample and the probe, which usually is a measurable and quantifiable quantity. (en) +
P
Profilometry is a technique used to extract topographical data from a surface. This can be a single point, a line scan or even a full three dimensional scan. The purpose of profilometry is to get surface morphology, step heights and surface roughness. (en) +
A technique used to measure the voltage of a cell under a low applied current as an estimate for the open-circuit voltage. (en) +
The pulsed electroacoustic (PEA) method is an established method for space charge measurements in polymeric dielectrics. (en) +
R
Raman spectroscopy (/ˈrɑːmən/) (named after physicist C. V. Raman) is a spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. Raman spectroscopy is commonly used in chemistry to provide a structural fingerprint by which molecules can be identified. Raman spectroscopy relies upon inelastic scattering of photons, known as Raman scattering. A source of monochromatic light, usually from a laser in the visible, near infrared, or near ultraviolet range is used, although X-rays can also be used. The laser light interacts with molecular vibrations, phonons or other excitations in the system, resulting in the energy of the laser photons being shifted up or down. The shift in energy gives information about the vibrational modes in the system. Infrared spectroscopy typically yields similar yet complementary information. Typically, a sample is illuminated with a laser beam. Electromagnetic radiation from the illuminated spot is collected with a lens and sent through a monochromator. Elastic scattered radiation at the wavelength corresponding to the laser line (Rayleigh scattering) is filtered out by either a notch filter, edge pass filter, or a band pass filter, while the rest of the collected light is dispersed onto a detector.

Direct output of the equipment with the manufacturer’s software including automatic pre-processing that is not modified by the user once the acquisition method is defined and the equipment calibrated. The raw data is a set of (unprocessed) data that is given directly as output from the detector, usually expressed as a function of time or position, or photon energy. (en) +
S
Act of extracting a portion (amount) of material from a larger quantity of material. This operation results in obtaining a sample representative of the batch with respect to the property or properties being investigated. (en) +
Analysis of the sample in order to determine information that are relevant for the characterisation method. (en) +
Parameter used for the sample preparation process. (en) +
DC polarography with current sampling at the end of each drop life mechanically enforced by a knocker at a preset drop time value. The current sampling and mechanical drop dislodge are synchronized. In this way, the ratio of faradaic current to double layer charging current is enhanced and the negative influence of charging current is partially eliminated. Due to the improved signal (faradaic current) to noise (charging current) ratio, the limit of detection is lowered. (en) +
