How does the OptiEnz sensing system work?

OptiEnz Sensors provides an easy-to-use instrument that consists of a small optical transceiver connected to a sensor via a fiber optic cable. Enzymes and a fluorescent chemical (fluorophore) are placed on the tip of the sensor, and the sensor tip is placed into the water being analyzed. The optical transceiver transmits light, via the fiber optic cable, to the sensor tip. As the enzymes react with chemical in the water, the characteristics of the fluorophore change and emit light. The optical transceiver detects the light characteristics and converts this to data readings that are continuous, specific, and quantitative measurements of the chemical concentration.

How are the measurement results accessed?

The optical transceiver provides a data output via USB that can be connected to a Windows PC.  OptiEnz provides a Windows-based PC software application, the OptiEnz Viewer, for controlling the sensing system and viewing and logging results. The optical transceiver also provides 0 – 5V and 4 – 20mA outputs that can be used to interface with a SCADA system (supervisory control and data acquisition) for controlling industrial processes or for telemetry applications.

What organic chemicals can the sensors measure?

OptiEnz has developed a variety of sensor tips designed to measure a wide range of specific organic chemicals, including hydrocarbons, solvents, alcohols, and sugars.

Are the measurements specific and quantitative?

Yes. The OptiEnz sensing system identifies the presence of specific organic chemicals (e.g., pinpointing benzene in the BTEX group of chemicals) and provides a quantitative measurement of concentration (e.g., 5 ppm of benzene).

Are there other products that can do the same thing?

Although other products measure organic chemicals in water, the OptiEnz sensing system is the only product capable of producing continuous measurements that are specific, quantitative, and in-place providing immediate feedback about the concentration of a variety of organic chemicals in water and aqueous solutions.

What applications are the sensors used for?

The OptiEnz sensing system is ideal for a variety of applications, including:

  • Biotech industrial fermentation processes including biopharmaceutical development and biofuel production
  • Measuring contaminants in produced water and flowback water generated from oil and gas well fracking operations
  • Beverage process monitoring
  • Water quality monitoring, including groundwater
  • Contaminated site remediation and characterization
What are the advantages of using the OptiEnz sensing system?

Unlike traditional water sampling methods, including gas and liquid chromatography, the OptiEnz sensors provide immediate results, can be used in-place, and do not require sample pretreatment, expensive equipment, or skilled labor. They also offer a significant cost savings when compared with the expense of sending samples to an analytical laboratory.

How do the sensors compare to chromatography?

The sensors produce the same accurate measurements as lab analyses generated from gas or liquid chromatography. However, unlike gas and liquid chromatography, the sensors allow for continuous, in-place monitoring.

How long does a sensor tip last?

The sensor tips are replaceable and the average life of a single sensor tip is one month, depending on operating conditions.

How much does it cost? Is there a large upfront investment?

The only initial investment required is the small optical transceiver. Contact us for a quote at
