A chromatographic testing device which is configured to select an imaging scheme according to the type of fluorescent dye in an immunochromatographic test cartridge and a method for controlling the same are disclosed. The chromatographic testing device can include: a body; a code expression recognition unit provided in the body and recognizing a code expression in which a type of fluorescent dye of an immune strip provided on an immunochromatographic test cartridge mounted on the body is recorded; an excitation light source emission unit for emitting light from an excitation light source to the immunochromatographic test cartridge; an image sensor unit for recognizing excitation light generated by the excitation light source; and a control unit for controlling the image sensor unit in a single imaging scheme or a cumulative light imaging scheme according to the type of fluorescent dye of an immune strip, recognized by the code expression recognition unit.

The present invention relates to a method for simultaneously qualitatively and quantitatively analyzing compounds of aldehydes and/or ketones in a short time by using an optimal TLC plate, a proportion of a developing solvent, a sample amount, etc., and can provide an analysis result equivalent to a conventional analysis result in a shorter time by providing the most optimal conditions when using the TLC method.

The present disclosure relates to imaging agent formulations, methods for preparing imaging agent formulations and methods for using the same. The present disclosure also relates to kits for imaging agent formulations.

This present application relates generally to a testing device for selecting a surfactant during oilfield subterranean operation technologies. More specifically, the application relates to providing a testing device for selecting a surfactant depending on the interaction of the surfactant with a combination of variables, including the formation hydrocarbon, source water and formation mineralogy.

Provided in the present disclosure are a traditional Chinese medicine composition for treating novel coronavirus pneumonia, a preparation method, a detection method, and the use thereof. The traditional Chinese medicine composition is mainly prepared from the following raw materials in parts by weight: 250-400 parts of Citri reticulatae pericarpium, 100-200 parts of Atractylodis rhizoma, 100-200 parts of Magnoliae officinalis cortex, 200-300 parts of Glycyrrhizae radix et rhizoma, 200-300 parts of Agastache rugosus, 200-300 parts of Acori tatarinowii rhizoma, 250-330 parts of Jujubae fructus, and 100-200 parts of Zingiberis rhizoma recens. Further provided in the present disclosure are a preparation method and a detection method for the traditional Chinese medicine composition.

The present disclosure provides a new series of compounds exhibiting high fluorescence quantum yields in the solid state. In one embodiment, the compounds include a series of 2,3,4,5-tetraphenylgermoles with the same or different 1,1-substituents. In another embodiment, substituted germafluorenes, germa-fluoresceins/rhodamines, and germapins are described. These germanium heterocycles possess ideal photophysical and thermostability properties, which makes them excellent candidates for chemical or biological sensors, host materials for electroluminescent devices and solar cells, and emissive and/or electron-transport layer components in organic light emitting diode devices.

The present invention provides methods in the context of Kawasaki disease including measuring the level of at least one of lipopolysaccharide binding protein, leucine-rich alpha-2-glycoprotein, angiotensinogen and retinol binding protein 4 in a sample derived from a subject.

A method for of validating the identity of one of more component(s) in a substance including: obtaining a substance; placing the substance in a plenum with a sealed bottom; exposing the substance to a perturbation; digitally recoding the time-dependent changes in the substance after exposing the substance to the perturbation; producing a chronological fingerprint of the changes, where the chronological fingerprint is a digital multi-dimensional image of the changes as a function of time; and comparing the chronological fingerprint to chronological fingerprints for known substances to validate the one or more component(s) in the substance being measured. Also described are associated systems and computer program products for implementing the method.
