Abstract
An analytical device configured for the introduction of the liquid or solid sample into a sample chamber where it is extracted by a chlorinated hydrocarbon solvent, wherein the extract then passes into a chamber where it undergoes a Friedel-Crafts (FC) reaction.
Claims17
A spectrometric analysis system comprising:
- a sample extraction chamber disposed in a housing for providing a sample extract;
- a reaction chamber disposed in the housing for contacting the sample extract with a catalyst to generate chromophoric signals produced by Friedel-Crafts reactions;
- and
- a spectrometer comprising diffraction grating coupled to a charge-coupled device, wherein the spectrometer is disposed in the housing configured to read the chromophoric signals in the near ultraviolet and visible portions of the electromagnetic spectrum in response to dispersing the chromophoric signals through the diffraction grating of the spectrometer.

A spectrometric analysis system comprising:
- a sample extraction chamber configured to receive a sample of geological fluids, and wherein the sample extraction chamber is in fluid communication with a valve for regulating a flow of a solvent into the sample extraction chamber for producing a sample extract from the sample of geological fluids;
- a catalyst tape including a plurality of separate catalyst packets disposed linearly along the catalyst tape;
- a reaction chamber for contacting the sample extract with at least one of the catalyst packets of the catalyst tape to generate chromophoric signals produced by Friedel-Crafts reactions;
- a motorized catalyst tape drum configured to displace the catalyst tape through the reaction chamber;
- a spectrometer configured to read the chromophoric signals;
- and
- a downhole tool to contain the sample extraction chamber, the valve, the reaction chamber, and the spectrometer, and to receive the sample of geological fluids.
