A SAP evaluation apparatus includes: a main body installed with a lifting bar that is raised or lowered; a container portion installed under the lifting bar in the main body and having an internal containing space for containing an absorber; an operating portion connected to the lifting bar and having a lifting plate that is raised or lowered within the containing space and applies pressure to the absorber and an injection portion for injecting an ink in the direction of the absorber; a dispersion measurement portion for measuring the dispersion of the ink through the absorber; and a controller installed at the main body to measure absorption of the ink into the absorber and measure swelling capacity of the absorber while the ink is injected into the absorber.

The disclosure relates to a manufactured composition, material or device comprising at least two different nonradioactive isotope atoms. Each nonradioactive isotope atom is present in an amount sufficient to increase the total amount of the nonradioactive isotope atom above the total amount found in the manufactured composition, material or device in the absence of adding the nonradioactive isotope atom to increase said total amount. The ratio(s) of the at least two nonradioactive isotopes in the manufactured composition, material or device are measurably different than the ratio(s) found in the manufactured composition, material or device in the absence of adding the nonradioactive isotope atom to increase said total amount.

The present invention relates to a method for determining the migration potential of an at least partially cured energy curing ink and/or varnish printed on a substrate comprising: —providing a substrate, which is printed with the ink and/or varnish, which comprises at least one extractable compound, which absorbs or emits radiation at at least one wavelength between 190 and 3,000 nm, —cutting at least one sample from the printed substrate, placing and incubating the sample in a solvent, in which the extractable compound is soluble, and removing the sample from the solvent to obtain a solvent extract, —quantitatively measuring a spectroscopic characteristic of the solvent extract at at least one wavelength between 190 and 3,000 nm, at which the extractable compound absorbs or emits radiation, so as to obtain a measured numeric value of the spectroscopic characteristic, and —comparing the measured numeric value of the spectroscopic characteristic with a calibration curve.

A method for assessing damage to a composite material covered with a polyurethane-type paint is provided. Two separate criteria are measured on a spectrogram obtained by infrared spectrometry, thereby characterizing thermal ageing of the paint, each separate criteria being a measurement on a curve of a spectrum of the spectrogram of a height of a particular peak, thereby giving two independent assessments of the thermal ageing. Then, the two separate criteria are combined together in order to obtain a result of a level of the damage.

There is described an equipment and method for analysis of a fluid, suspension, solution, dispersion or fluid emulsion that automatically analyzes the characteristic properties of the samples of the fluids, such as paints, enamels, and dyes, among others, so that adjustments can be made to the fluid to meet the optical properties such as color, opacity, hue, saturation (tinting power), covering and luminosity, from the spectrometric measurement technique by transmission analysis of film having radiated fixed thickness.

An apparatus and method for simultaneously measuring water content profiles, surface/interfacial levels, thicknesses and tensions of multiphase dispersions, such as dispersions with water dispersed in produced oils, crude oils, various fuels, distillates, lubricants, paints and polymers, or reversed dispersions with these organic components dispersed in water. The apparatus with 1-16 channels, namely multi-channel scanning water analyzer (MCSWA) and/or tensiometer, comprising a motorized precision vertical stage with multiple capacitive sensors, a heating system with multiple heating cells for keeping the respective sample bottles, and a data acquisition system, where the capacitive sensors can be precisely controlled via a computer to dip into the samples at a preset scanning velocity and the capacitances of the sensors are continuously measured by the data acquisition system.
