Chemi-Sense pH Field Screen for Complex Hydrocarbon Samples

Screen the pH of the aqueous portion (free or emulsified water) of hydrocarbon and produced-water samples, pH 4 to 11, in about 2 minutes at ambient with the patent-pending Chemi-Sense pH film. Do not heat. It is not dry-oil pH and not a TAN substitute.

Aqueous-portion pH in the field, in about 2 minutes.

Routine lab analysis can delay decisions. This test reads the aqueous portion (free or emulsified water) of hydrocarbon samples in about 2 minutes at ambient. It is not a dry-oil pH measurement or a substitute for TAN analysis.

This portable, self-contained test provides measurable, repeatable results for the aqueous portion of hydrocarbon samples, including free or emulsified water, supporting same-day system adjustments without waiting for laboratory turnaround. It is intended for aqueous-phase pH, not dry-oil pH, and does not replace TAN analysis.

Key Advantages

Reliable results in 2 minutes at ambient.
Eliminates shipping and lab delays.
Enables on-site monitoring and rapid corrective action.
Compact, easy-to-use design with minimal training required.

Procedure

Collect sample with aqueous / free or emulsified water present.
Immerse the sensor film for 2 minutes.
Gently blot excess liquid.
Keep at ambient — do not heat.
Color develops in under 2 minutes.
Compare to the calibration chart.

Simple. Fast. Reliable.

FAQs

Each kit includes sensor film, calibration chart, sample container, drying container, and user instructions.

It estimates the pH of the aqueous portion (free or emulsified water) of a sample, from pH 4 to 11. It is not dry-oil pH and not a TAN substitute.

About 2 minutes at ambient. Do not heat the pH film. Follow the kit insert.

At least 2 minutes at ambient; do not heat.

The sensor provides reproducible results from pH 4 to 11; see the calibration chart.

No. The kit 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 pH.

Develop at ambient; do not heat pH films. Public timing is 2 minutes at ambient per current kit insert.

This is a field screen. If your stream contains other chemicals, contact us with your sample matrix before relying on the reading.

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

Ensure the film remains immersed for the full 2 minutes at ambient; do not heat. 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. Follow the kit insert.

Store the sealed bag at room temperature, away from direct sunlight and heat, per the kit insert.

Follow the kit insert. The current pH insert specifies room-temperature storage in the sealed bag, not refrigeration.

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

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

It’s designed for batch or spot testing, not continuous monitoring. Continuous monitoring technology is under development.

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

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

It is not designed to be inserted into high-pressure lines. Collect a representative sample and test it per the kit insert.
