order now INSTRUCTIONS

Obtain accurate amine residual data in the field in 35 minutes at 167°F with the kit warmer (MEA-based).

Fast, Accurate Amine Residual Testing of Corrosion Inhibitors.* Right in the Field.

Routine lab analysis can delay critical decisions. Now, obtain accurate amine residual data of your corrosion inhibitors in the field in 35 minutes at 167°F with the kit warmer using the patent-pending Chemi-Sense Amine Sensor System.*

This portable, self-contained test provides measurable, repeatable results that allow for same-day system adjustments and optimized inhibitor dosing without waiting for tedious laboratory turnaround.

Key Advantages

  • Reliable results in 35 minutes at 167°F with the kit warmer; the warmer can be used near the end.
  • Eliminates shipping and lab delays.
  • Enables on-site monitoring and rapid corrective action.
  • Compact, easy-to-use design with minimal training required.

Procedure

  • Collect your sample.
  • Immerse the provided sensor film for at least one minute.
  • Transfer the film to the clean, dry container; for low-range reads use the kit warmer for 35 minutes at 167°F.
  • Compare the developed film color to the provided calibration scale to determine inhibitor concentration.

Facts About the Amine Residual Field Test

  • Sensor response: 0–10 ppm and 20–300 ppm (MEA-based).
  • Applications: primary and secondary amine corrosion inhibitors or low-level concentrations in process plants.
  • Reproducible results.
  • Low-range response: 35 minutes at 167°F with the kit warmer; warmer can be used near the end.
  • 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.

With the kit warmer, the 0–10 ppm test range can be completed in 35 minutes at 167°F. Timing depends on amine concentration and temperature; follow the kit warmer protocol for the applicable range.

At least 1 minute.

The sensor provides reproducible results across the published ranges of 0–10 ppm and 20-300 ppm.

No. Use the field test as a rapid field check, not as a substitute for a lab analyzer or specialized laboratory gear.

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

Yes. Response time depends on temperature; warmer conditions support faster color development. The kit warmer protocol specifies 35 minutes at 167°F for the 0–10 ppm range.

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.
