The present invention discloses an apparatus and a method for measuring components in fluidic samples in a non-invasive fashion using Infrared (IR) transmission spectroscopy. Fluidic samples are sealed in flexible IR-transparent bags that are then fixed on a supporting bed. The supporting bed is then mounted between the front and back plates of the apparatus so that the bag is squeezed by two IR transparent windows from opposite directions until the windows contact the spacer sheet mounted on the back plate. The thickness of the spacer sets the gap distance between the two windows and thereby sets the optical path for the measurement in the transmissive mode.

Biosensor systems for detecting levels of nitrogen-containing molecules are provided. Further provided are biosensor system components and various detection platforms, methods, and kits.

A system for monitoring at least one parameter of a fluid contained in a container includes a measuring device based on near-infrared spectroscopy designed to be submerged in the cited fluid to be monitored and to take measurements of the fluid. The measuring device includes a measuring area. The monitoring system includes a flotation system joined to the measuring device. The flotation system is arranged, during the use of the monitoring system, floating on the fluid to be monitored such that the measuring area of the measuring device is submerged in the fluid at a constant depth with respect to the level of fluid in the container, such that all the measurements taken by the measuring device are taken at the same depth with respect to the level of the fluid.

A measuring apparatus for measuring a property of a medium includes: a density instrument for measuring a density of the medium; a speed of sound instrument for measuring a speed of sound in the medium; a temperature device for measuring a temperature of the medium; and an electronic circuit, wherein the foregoing components are arranged in a housing wherein the speed of sound instrument includes a pressure measuring cell, wherein the electronic circuit is configured to determine a compressibility from pressure measurements for at least two different pressure measuring cell volumes and to determine a speed of sound in the medium from the compressibility, wherein side surfaces of the pressure measuring cell each have a surface area of at most 0.5 square centimeter, and wherein the pressure measuring cell has a maximum volume of less than 5 cubic centimeters.

The present invention pertains to the measurement of the refractive index of a medium, such as a fluid, through the wall of its container. The essential characteristic of the invention is that, by using at least two separate light paths that are of unequal length and that reflect from the wall/medium interface, it is possible to perform the measurement of the refractive index of the medium so that the result is insensitive to the color and thickness of the wall.

The invention relates to a method for detecting, quantifying and differentiating by flow cytometry Brettanomyces spp yeast cells contained in an organic liquid substrate which contains fermentable sugars, whereby a sample of said substrate is taken, optionally diluted, at least a first fluorochrome capable of binding to the DNA of dead and/or live cells is added to said optionally diluted substrate, said sample is irradiated so as to obtain the fluorescence emission of said first fluorochrome and said sample is also irradiated so as to obtain a fluorescence emission of said sample at 670 nm, a biparametric histogram is plotted giving for each point the fluorescence intensity due to the first fluorochrome coupled with the fluorescence intensity emitted at 670 nm, at least a first point cloud is thus obtained corresponding to a greater fluorescence intensity emitted and detected at 670 nm than that detected for the other points, it is inferred therefrom that the points of said first cloud correspond to the Brettanomyces spp cells.
