Procedure

  • Collect your sample.
  • Immerse the provided sensor film for at least one minute.
  • Transfer the film to the clean, dry container for up to five hours.
  • Compare the developed film color to the provided calibration scale to determine inhibitor concentration.

Facts About the Amine Residual Field Test

  • Sensor response: accurate from 0 to 300 ppm at 25 to 50 ppm intervals.
  • Applications: primary and secondary amine corrosion inhibitors or low-level concentrations in process plants.
  • Reproducible results.
  • Maximum response time for low levels is 5 hours at 70°F. Higher temperatures will respond faster.
  • Higher concentrations of amine respond faster than maximum time.
  • Minimum exposure time to sample is 1 minute.
  • Demonstrated no interference in crude or produced water.

Simple. Fast. Reliable.

FAQs

Each test includes a film, calibration chart, drying container, and user instructions.

It measures residual concentrations of primary and secondary amine inhibitors in a sample, expressed in ppm (parts per million).

No. It is designed and validated for primary and secondary amines only (such as MEA). It does not work with tertiary amines.

You can obtain accurate results within 5 hours, depending on amine concentration and temperature. Higher concentrations or higher temperatures produce faster results, most within 25 minutes.

At least 1 minute.

The sensor provides reproducible results from 0–300 ppm, with calibration intervals of 25–50 ppm.

No. The system is self-contained and portable—no external lab tools or analyzers are required.

Compare the developed film color against the included calibration scale to determine amine concentration.

Yes. The specified 5-hour maximum response is at 70°F (21°C). Warmer conditions produce faster color development.

There are no known interferences, the sensor is only sensitive to primary and secondary amines. Contact us if an interference is a concern.

No. Each film is single-use only for one test.

Ensure the film remains immersed for the full minute. Drying during exposure time may increase the reaction time.

Yes. Always view color under consistent lighting and use the provided chart.

Shelf stability is still being tested. Current recommendation: use within 4 months of receiving.

Keep at room temperature, away from direct sunlight or high humidity.

Yes, cooler temperatures extend stability of the sensor. We are still testing shelf stability.

Dispose of used films and sample residues according to your facility’s chemical waste procedures.

No formal training required. The kit comes with easy instructions.

It’s designed for batch or spot testing, not continuous monitoring. We are currently developing a continuous monitoring technology. If amine concentration increases, the sensor will continue to respond to higher levels but will not respond to levels lower than previously measured.

If color appears inconsistent or outside the range, retest with a fresh film and verify sample handling steps.

Contact Chemi-Sense support to discuss compatibility or future sensor variants.

A digital companion app for automatic color quantification is under evaluation. Stay tuned for updates.

It is not currently capable of inserting into high-pressure lines. Collect a representative sample before testing. The sensor has been successfully tested to 200°F.
