Abstract: A device for collecting light emitted by a laser source, including an optical wave guide arranged so as to collect a light signal emitted by the laser source, by coupling. The wave guide includes a loop coupled to a laser source in two coupling zones making it possible to recover optical modes circulating along the direction opposite to the required direction for the signal output from the device.

Abstract: A method for analyzing molecular pollutants of a fluid. From a calibrated flow of fluid, a combination of a measurement of a total amount of molecular pollutants and a determination of chemical compositions and relative amounts of the molecular pollutants by adsorption on materials is carried out. The determination of the chemical compositions and relative amounts advantageously occur after a threshold value for the total measured amount is exceeded.

Abstract: A model of evolution of a signal of a chromatographic column is formed, then inversed as a function of the measured signals, to calculate solute concentrations by using the entire signal. The model is based on equations that govern the transport of solutes in the column as a function of various physical parameters, which can be re-evaluated. The method can be used for searching and measuring rare components, such as proteins, in liquid biological samples.

Abstract: A process for measuring the gradient or an n-th order derivative, in which n is greater than 1, in a direction z, of a component Hx of a magnetic field, the component being invariant, at least locally, in a direction y. The method includes: a) positioning of N (N>n+1) elementary field sensors, each sensor being offset, relative to the neighboring sensors, along y by a distance Ty and along the z axis by a distance ?z, b) measurement of the field by each of the N sensors, and c) calculation of the desired gradient, or the desired nth-order derivative, as a function of the measurements of the field obtained during b).
