The invention concerns a fluid distribution device () comprising:

Fluid distribution device

A method and apparatus for capturing a chemical compound, typically an impurity, and for accumulating said chemical compound on a capture mass CAPT included in at least one removable adsorbent cartridge MC over a period exceeding 2 days, with a view to the external chemical analysis thereof. The apparatus ST suitable for capturing at least one chemical compound in a fluid flow for its detection and/or quantification comprise, downstream of said cartridge or cartridges, at least one device for measuring the cumulative flow which has traversed the cartridge or cartridges over a set time period. In a preferred variation of the invention, the capture mass CAPT is fragmented into a plurality of elementary masses CAPTi which allows for the spread of an irreversible adsorption front or the displacement of a chromatographic zone.

Method and apparatus for detecting and quantifying a chemical compound in a fluid flow

For testing performance levels and/ or changes over time of at least one catalyst (CAT) for a fixed-bed reactor: a device (CT) for a test, comprising at least one hollow metal cartridge (MC) containing the catalyst (CAT) is connected at a point A of an industrial chemical installation containing a reaction feedstock suitable for testing the catalyst (CAT); a liquid stream containing a fraction that is less than or equal to 1% of preheated reagents circulating in the industrial chemical installation is circulated in the cartridge (MC) through the catalyst (CAT) and sampled at a reaction temperature for a period (T), and returned to the industrial chemical installation at point B downstream of the device.
