AJ-05 Arsenic Detector for Elevated-Level Screening
The ChemSee AJ-05 arsenic detector is a rapid colorimetric test designed to screen food, beverages and water for elevated levels of arsenic. The test uses a prepared liquid sample and produces a visible color response that is compared with the supplied reference chart.
500 ppb Detection Threshold
The AJ-05 is designed for higher-level arsenic screening with an approximate detection threshold of 500 parts per billion (ppb).
Results in Minutes
The detector develops a visible color response that can be compared directly with the supplied arsenic reference chart.
Liquid or Prepared Samples
Liquids may be tested directly. Solid foods are mixed with water so the liquid portion can be introduced into the detector pouch.
Looking for trace-level arsenic testing? The AJ-05 is intended for elevated-level screening rather than low-level environmental arsenic measurement. For lower concentrations, see our Trace Arsenic Detectors →

How the AJ-05 Arsenic Test Works
Prepare the sample, activate the detector pouch, expose the detection strip and compare the resulting color with the supplied reference chart.
Prepare
Liquids: Use the sample as-is.
Solid foods: Chop into small pieces and mix with approximately an equal volume of clean water.
Add Sample
Remove the white detection strip from the pouch and add the liquid portion of the prepared sample to the marked fill line.
Activate
Seal the pouch with the supplied clip. Break the two internal ampules through the plastic holder and gently massage the pouch for approximately 10–15 seconds.
Develop & Read
Unseal the pouch, insert the detection strip through the two upper holes and hold the pouch upright for approximately 90 seconds.
Remove the strip and compare the developed color with the supplied chart.
Interpreting the Arsenic Test
The AJ-05 produces a visible color response that becomes stronger as the detected arsenic level increases.
Compare the Developed Strip
After the reaction period, compare the detection strip with the reference chart supplied with the AJ-05.
- No visible arsenic response — no characteristic color develops.
- Lower positive response — a lighter yellow / tan response may develop.
- Higher positive response — a stronger orange / brown response may develop.
Always use the supplied instructions and reference chart when interpreting the result.
Important: Colorimetric screening results can be affected by sample composition, preparation, dilution and other matrix effects. The AJ-05 provides a screening result rather than a laboratory concentration measurement.

Elevated-Level vs. Trace Arsenic Testing
Elevated Arsenic Screening
Use the AJ-05 when the concern is a comparatively high arsenic level, including situations involving suspected intentional contamination of food or beverages.
Approximate threshold: 500 ppb
Lower-Level Arsenic Testing
For applications where lower concentrations of arsenic are important, including trace-level screening, use the ChemSee Trace Arsenic Detector instead.
Rapid Screening — Not Laboratory Quantification
The AJ-05 is designed as a rapid colorimetric screening test for elevated arsenic levels in submitted food, beverage and water samples. The visual result indicates whether arsenic is detected under the conditions of the test; it does not provide a precise numerical arsenic concentration.
For customers who prefer professional sample analysis rather than performing a field test, ChemSee also offers mail-in laboratory testing.
