摘要： A method for preparing an intermediate by a reduced glutathione-indicated amino acid Maillard reaction is provided. The method includes a two-stage reaction at an increased temperature. A reduced glutathione is added after different times of a low-temperature reaction, and a subsequent Maillard reaction is effectively inhibited on a basis wherein a substance is interacted with an intermediate degradation product to reduce a formation of colored substances. Comparing with a browning of Maillard products after a high-temperature stage, a reaction time with a best color inhibition effect is found to be the optimal preparation condition of the intermediate, and the intermediate is prepared in an aqueous medium at a low temperature under this optimal preparation condition. The method uses the water soluble reduced glutathione as a tracer to improve a tracing accuracy comparing to cysteine.

摘要： The invention relates to a method for determining concentrations of absorbing gases by means of a spectroscopic measuring device, wherein wavelength-dependent measurement values for a light intensity are obtained and a wavelength-dependent measurement value function is represented based on these values. A wavelength-dependent theoretical function is defined, which includes as parameters a calibration parameter and the concentrations. The calibration parameter is defined as a function of a device parameter and a correction parameter that depends on the concentrations. A cycle comprising a sequence of steps is performed several times in a row, wherein in a first step a numerical value for the correction factor is calculated from stipulated assumed values of the concentrations, wherein in a second step the theoretical function is determined using the calculated numerical value, wherein in a third step values for the concentrations are obtained by a curve adjustment calculation between the theoretical function determined in the second step and the measurement value functions and are stipulated as new assumed values. The assumed values obtained in the third step of the last cycle are output as new measured values.

摘要： A method for simultaneously measuring the activities of multiple kinds of enzymes in single channel through concimitantly monitoring multiple wavelength absorbances is claimed; based on linear additivity of absorbances and the isoabsorbance wavelengths of chromogenic substrates and their chromogenic products, both the principles for the combination of chromogenic substrates required for simultaneously measuring the activities of multiple kinds of enzymes in single channel through concimitantly monitoring multiple wavelength absorbances and an approach for data processing to eliminate the interference of the overlapped absorbances are developed, kinetic analysis of reaction curves via numerical integration eliminates the interference of all substrates and products and estimates the maximal reaction rates of the enzymes to be measured, giving the linear ranges and the limits of quantification for simultaneously measuring the activities of multiple kinds of enzymes in single channel comparable to those by separate assays; the present invention is applicable for simultaneously measuring the activities of multiple kinds of enzymes in biological samples, simultaneously measuring multiple components by enzyme-labeled immunoassays, screening simultaneously of inhibitors against multiple targets, for the practice in clinical biochemical analyses, clinical immunoassays, health laboratory analyses, the discovery of inhibitors, and the basical researches which need the present invention.

摘要： A new technique which uses a pump-probe methodology to place a molecule into one or more excited rotational and/or vibrational states. By evaluating spectral changes due to at least one discrete frequency of pump photons a multi-dimensional characterization of the molecule's excited state energy level results. This multi-dimensional characterization typically involves evaluating the changes between excited and unexcited state measurements. The differential nature of the evaluation makes the technique self-referencing and solves problems common to many spectroscopic techniques. The multi-dimensionality of the technique provides high specificity and immunity to interferents. The preferred embodiments involve excitation by using photons suited to pumping the rotational states and evaluating the effects by probing the energy levels of one of more vibrational states. The technique is capable of detecting bulk and trace concentrations of a molecule in gas, liquid and solid phases, both in pure form and in the presence of other molecules.

摘要： A diffusion-type NDIR gas analyzer with an improved response time due to convetion flow created by a temperature gradient between gas located within a waveguide and gas located within a diffusion pocket of space created between the waveguide and a semi-permeable membrane which surrounds the waveguide. The temperature gradient may be created by a thermally resistive radiation source that is not thermally isolated from the waveguide. The semi-permeable membrane is made of a hydrophobic material and has a thickness sufficient to provide its own structural integrity. The semi-permeable membrane can have a porosity less than approximately 50 mu m and be comprised of ultra high molecular weight polyethylene or TEFLON.
