Formation tester comprising reactive filter material sensors
First Claim
1. A sensor comprising:
- at least one reactive filter material arranged in a flow line, wherein the at least one reactive filter material sorbs an analyte in a wellbore fluid in the flow line; and
a first detector that detects a first sorption signal specific to the analyte at a first location upstream of the at least one reactive filter material and a second detector that detects a second sorption signal specific to the analyte at a second location downstream of the at least one reactive filter material, wherein the sensor either calculates a balanced measurement corresponding to the presence of the analyte in the wellbore or relays the first sorption signal and the second sorption signal to a signal processing unit configured to calculate the balanced measurement corresponding to the presence of the analyte in the wellbore;
wherein the calculation of the balanced measurement is based on the first sorption signal and the second sorption signal.

Abstract
The embodiments herein relate to sensors having reactive filter materials for detecting analytes in wellbores. The sensor includes at least one reactive filter material arranged in a flow line, wherein the reactive filter material sorbs an analyte in a wellbore fluid in the flow line; and at least one detector that detects a sorption signal specific to the analyte at at least a first location and a second location of the reactive filter material, wherein the first location is upstream in the flow line relative to the second location. The detector either (1) calculates a balanced measurement corresponding to the presence of the analyte in the wellbore or (2) relays the measurements to a signal processing unit to calculate a balanced measurement corresponding to the presence of the analyte in the wellbore.
