ACT In Situ Hydrocarbon Sensors Customer Needs and Use Assessment.....................................................21
13. Relative to the above (Questions #11 and #12) sensor system characteristics, are
any of your sensor needs or requirements “non-standard” or custom made?
Users: 91% (21) No; 9% (2) Yes.
Colleague Comments:
• Need to employ excitation and emission wavelengths that are more representative
of real (crude) oil fluorescence.
• We would like to speak with someone about developing user selectable ex and em
fluorometers, and user selectable amplifier gains. We are also interested in
changing the output of some of these sensors from linear outputs to logarithmic to
avoid changing gain settings in the field (i.e. automatic gain control ; "AGC").
AGC causes some grief in applying real time data corrections.
Vendors: 71% (5) Yes ; 29% (2) No.
Vendor Comments:
• Calibration standards.
• We can supply specific sensor configurations to meet individual customer
requirements.
• Some of our products are engineered to meet the customer’s needs. The monitors
suggested for this project are standard.
