    Abstract: An integrated apparatus includes a miniaturized flattened support having a planar surface whereon are formed wells and a microchannel, elements for projecting exciting light locally on an excitation zone of the microchannel along a direction forming an angle (α) greater than 60° with a longitudinal direction of the microchannel, optical collector elements coupled with one free end of the microchannel, optical measurement elements and processing elements, the microchannel having a portion forming a reservoir with internal cross-section flaring from its free end up to the excitation zone, the portion being extended by a conical, ellipsoidal or paraboloidal internal wall, and emerging onto a second microchannel portion with reduced internal cross-section, the latter communication with the wells.

    Abstract: The pneumatic element which causes partial opening of the choke valve is connected to the intake pipe by a duct having a calibrated restriction. The duct opens into the pipe at a point which is located downstream of the throttle valve under all operating conditions and at another point which is downstream of the throttle when the latter is in the "cold" minimum opening position.

    Abstract: A laser-induced fluorescence detector comprises a laser beam emitting device, a dichroic mirror to deviate the laser light orthogonally, a lens with a small numerical aperture, a ball lens, a unique cell within a capillary, the cell receiving a solute containing at least one unknown fluorescent substance at the laser wavelength, the same device collecting the fluorescence emitted by the fluorescent substance, with optical filters, a photomultiplier tube, and a computer for displaying results of the analysis. The ball lens converts the laser beam into a very small divergent beam, which allows a high irradiated volume in the capillary cell. The cell employs controlled geometric contours to prevent laminar mixing and turbulence during liquid flow, and the collecting device is a high numerical aperture device, for example, a ball lens.
