摘要： A chip-scale, reusable sensor can detect aromatic hydrocarbons, such as benzene, toluene, ethylbenzene, and xylenes (BTEX), rapidly in water without sample preparation. The device is capable of real-time, continuous monitoring for BTEX solutes, which diffuse into a film, such as a polymer, on the sensors surface. In operation BTEX analytes concentrate in the film, causing an increase in refractive index, which modulates evanescent coupling into the chips integrated photodetector array. Integration of the photodetector array simplifies system instrumentation and permits incorporation of an on-chip photocurrent reference region in the immediate vicinity of the sensing region, reducing drift due to temperature fluctuations. In some examples, the chip responds linearly for BTEX concentrations between 1 ppm and 30 ppm, with a limit of detection of 359 ppb, 249 ppb, and 103 ppb for benzene, toluene, and xylene in water, respectively.

摘要： An oil-in-water monitoring (OIWM) system for monitoring an oil-in-water concentration of treated water in a subsea processing system. The system includes a first OIWM portion including a separation component configured to separate the treated water stream into a separated oil portion and a separated water portion which has a plenum including the separated oil portion and the separated water portion. A separation component instrument is operatively coupled to the plenum. The system also includes at least two of: an oil line instrument operatively coupled to an oil line, a water line instrument operatively coupled to a water line, and an inlet line instrument operatively coupled to the inlet line. A computational device is configured to output an oil-in-water concentration of the inlet treated water stream using the parameters measured by the separation component instrument and at least two of the other instruments. Methods using such systems are also disclosed.

摘要： A real-time method and analytical system for determining haloacetic acids in water which operate by: (1) extracting samples on ion-exchange absorbent medium; (2) concentrating haloacetic acids on hyper-crosslinked medium; (3) eluting the analytes from the concentration medium for injection into an HPLC system; (4) separating individual haloacetic acid in reverse-phase chromatography performed by the HPLC system; and (5) measuring optical characteristics (UV-absorbance) of haloacetic acids, to determine concentration. The entire process can be performed using a completely self-contained, in-situ mechanism that sits at a water distribution point for 24/7 testing, with automated control, monitoring, reporting, and employment of remedial measures (e.g., automated adjustment of the water treatment process).

摘要： An analytical system and method periodically monitoring an injection water distribution pipeline for the presence and concentration of formaldehyde or other aldehyde-functional biocide includes pumps, one of which provides a predetermined volume of injection water drawn from the pipeline at a sampling point and the other a predetermined volume of a reagent, preferably a buffered solution of dimedone, from a reagent storage vessel which are mixed and then heated in a chamber to a predetermined temperature to promote formation of any reaction products. The heated reaction mixture is passed to a detection cell and exposed to light of predetermined wavelength which, in accordance with the Hantzsch reaction, molecules having an aldehyde functional group that reacted with dimedone produce a fluorescence-emitting reaction product, the intensity of which is measured and compared to data previously obtained from standard aldehyde-containing solutions.
