Abstract: A method for measuring activation energy of a catalyst is disclosed, which includes obtaining a resonant frequency change-time curve using an integrated self-heating resonant cantilever (100), converting the resonant frequency change-time curve into a resonant frequency change-temperature curve, converting the resonant frequency change-temperature curve into a coverage-temperature curve, obtaining a coverage change rate-temperature curve by performing first-order differentiation on the coverage-temperature curve, obtaining relevant parameters corresponding to local minimum values from the coverage change rate-temperature curve, and substituting the relevant parameters into calculation formulas to obtain a desorption rate constant of the catalyst and a desorption activation energy of the catalyst. It can be seen that the present disclosure simply requires programmed heating in terms of operating on the samples, which is fast and convenient. In addition, the method also has other advantages, such as, accurate measurement results, low consumption of samples, and low price.

Abstract: Disclosed is a thermal analysis device including a probe for applying a load to a sample S, a force generator for generating and applying a force to the probe, displacement detectors for detecting the displacement of the probe to measure the mechanical properties of the sample, a force signal generator for generating a force signal to activate the force generator, a load detector for detecting a load applied to the sample, and furnaces for heating the sample. The force signal generator includes a digital signal generator that generates a digital signal of the force signal, multiple D/A converters that convert the digital signals into analog signals, and multiple amplifiers that amplify each of the analog signals output from the respective D/A converters by different amplification factors. The force signal generator outputs the analog signal amplified by at least one of the multiple amplifiers as the force signal.

Abstract: A metal casting is heated using infrared energy by introducing the metal casting into a heating system with infrared emitters directed towards the casting, and activating at least a portion of the emitters. The heating system includes a heating chamber, a plurality of directional infrared emitters in the heating chamber, an optical temperature sensor directed towards a part location in the interior of the heating chamber, and a thermal shield that is movable between a deployed position and a retracted position, the thermal shield comprising an observation duct. The observation duct provides a line-of-sight path between the optical temperature sensor and the part location when the thermal shield is in the deployed position, and the thermal shield is between the plurality of infrared emitters and the part location when the thermal shield is in the deployed position.

Abstract: A device for measuring the total organic carbon content (TOC) of a sample fluid comprises a measuring cell (2) defining a volume (3) for containing a sample fluid and an excimer lamp (20) arranged to cause an oxidation reaction of the sample fluid by emitting radiation onto the sample fluid in the volume (3). A pair of electrodes is arranged to measure the conductivity of the sample fluid during the oxidation reaction and at least one temperature senor (31) is arranged on the measuring cell (2) to measure a temperature that is related to the sample fluid. The total organic carbon content (TOC) of the sample fluid is determined on the basis of the measured conductivity compensated by the temperature related to the sample fluid.
