    Abstract: In one aspect, the disclosure provides methods of distinguishing a glycosaminoglycan from one or more other components in a sample by subjecting the sample to size-exclusion chromatography using a mobile phase having a pH of 6.8 or lower. A mobile phase having a pH of 6.8 or lower is found to improve the separation of glycosaminoglycans from proteins during size exclusion chromatography. In some embodiments, improved separation is due to the low pH of the mobile phase causing elution of less dispersed fractions of the protein and/or glycosaminoglycan. In some embodiments, the overlap between protein and/or glycosaminoglycan fractions is reduced.

  • Patent number: 8778085
    Abstract: A dissolved nitrogen concentration monitoring method is used for monitoring a dissolved nitrogen concentration of a cleaning liquid when an ultrasonic wave is irradiated onto the cleaning liquid in which a substrate is dipped. The method includes measuring an amount of increase of a dissolved oxygen concentration of the cleaning liquid resulting from an oxygen molecule generated from a water molecule as a result of a radical reaction caused by ultrasonic wave irradiation. A dissolved nitrogen concentration of the cleaning liquid is calculated from the measured amount of increase of dissolved oxygen concentration based on a predetermined relationship between a dissolved nitrogen concentration and an amount of increase of dissolved oxygen concentration.

  • Patent number: 8746047
    Abstract: Provided is a method for analyzing a dispersion made by dispersing a liquid or solid dispersoid into a liquid dispersion medium. The method includes the steps of: preparing a sample liquid from the dispersion by forming an agglomerate of the dispersoid in the dispersion medium; redispersing the dispersoid that forms the agglomerate in the sample liquid into the dispersion medium of the sample liquid; and measuring the amount of the dispersoid that has been redispersed from the agglomerate in the sample liquid.

  • Publication number: 20140150535
    Abstract: In a urine component analysis device, a correlation storage section stores data indicating a correlation between a measured concentration in one urine and in total urine in one day for each of a first and second specific component in the urine excreted by a human. A data input section inputs data indicating a concentration of the first specific component and of the second specific component in one urine of a subject. A concentration of the first specific component and of the second specific component in total urine in one day are determined by performing conversion using the correlation stored in the correlation storage section based on the concentration of the first specific component and the second specific component in the one urine. A concentration ratio between the first specific component and the second specific component in total urine in one day is determined based on the results of conversion.

  • Patent number: 8733153
    Abstract: A system for determining a quality and/or depth of a fluid in a tank. The system includes a controller, one or more transducers, and a temperature sensor. A fixed distance transducer transmits a sound wave toward a fixed surface. A depth transducer transmits a sound wave which reflects off a surface of the fluid. The temperature sensor senses a temperature of the fluid in the tank and provides an indication of the temperature to the controller. The controller measures the elapsed time for the sound waves to travel between the fixed distance transducer and a fixed surface and the elapsed time for the sound waves to travel between the depth transducer and the surface of the fluid held within the container. Using the elapsed times and the temperature of the fluid, the controller is able to determine a quality and the depth of the fluid.

  • Patent number: 8726722
    Abstract: Systems and methods for determining concentrations of components of a multiphase fluid. A first flowmeter receives a fluid flow and generates measurements of the fluid flow. After at least partially separating the fluid flow into mixtures of its components, second and third flowmeters generate measurements of the mixtures. A data processing apparatus operatively coupled to the flowmeters receives the measurements and determines concentrations of the components of the fluid flow. In an embodiment, the measurements are mass flow and density readings.
