Abstract: In a first step, a sample liquid is fabricated by mixing a sample formed of a polyester or decomposition products of a polyester into a solvent. The solvent used here contains chloroform and 2,2,2-trifluoroethanol and has an organic base added thereto. The organic base is at least one of a primary amine, a secondary amine, a tertiary amine and a heterocyclic amine. Next, in a second step, each of the amount of the terephthalic acid terminal and the amount of the hydroxy group terminal in the sample liquid is measured through a nuclear magnetic resonance spectroscopy aiming at hydrogen atoms. Subsequently, in a third step, the number average molecular weight of the sample is calculated from the amount of the terephthalic acid terminal and the amount of the hydroxy group terminal measured in the second step.

Abstract: A specimen tube comprises a tubular body having a first end that is open, a second end that is closed and at least one side extending axially between the first end and the second end. The side and the closed end define an interior of the tube. In sonic implementations, the specimen tube comprises a plurality of foot members protruding from the second end of the tube, wherein at least a first foot member and a second foot member have different shapes from each other. In some implementations, at least one internal wall positioned within the interior of the tube defines a sample carrier holding space between at least one surface of the internal wall and an adjacent surface of the side of the tube, the sample carrier holding space being sized to store a swab inserted from the open end of the tube.

The present invention relates to a method for measuring an analyte concentration in a specimen, including (1) preparing the specimen, (2) mixing a coloring reagent, an oxidoreductase, and a light-scattering adjustment reagent with the specimen to obtain an analysis sample having substantially the same scattered light as the specimen, and (3) measuring the analyte concentration by using the analysis sample.

Abstract: Described herein are methods for quickly measuring properties of grain kernels. The methods allow for a quick, qualitative assessment of high amylose content in the grain kernel. The methods described herein allow for the assessment of high amylose content in wheat in either a laboratory setting or in the field with a minimum of equipment required. The results of these methods may be used to determine if high amylose kernels have been contaminated with normal or low amylose kernels.
