Example Colorimetric Responses from ChemSee Detectors
These photographs and videos show representative positive responses produced by selected ChemSee explosive and precursor detectors. Color and intensity can vary with the target material, sample loading, matrix, lighting, detector condition and test procedure.
Always interpret a result using the instructions and reference colors supplied with the detector. Example images are educational references—not a substitute for the current product instructions or confirmatory analysis.
Nitro-Pen
Nitro-organics and nitramines; applicable inorganic nitrates with the supplied Z-Pad.
Nitro-Pen Results
Representative RDX Response
The image shows a positive color response obtained during screening of an RDX sample with the Nitro-Pen detector. The test-response stage and resulting reference color are used together for interpretation.
- Detector class: Nitro-Pen
- Target class: Nitramine explosive
- Example target: RDX
- Result type: Presumptive colorimetric response
On-The-Spot Results
Representative Ammonium Nitrate Response
On-The-Spot is focused on inorganic nitrate residues. This example shows the detector response produced by an ammonium-nitrate sample under the demonstrated procedure.
- Detector class: On-The-Spot
- Target class: Inorganic nitrate
- Example target: Ammonium nitrate
- Result type: Presumptive colorimetric response
Verifier Results
Representative Liquid-Precursor Responses
The Verifier has two distinct response regions—one for selected oxidizers and one for selected flammables. The example demonstrates how the two target categories can produce distinct color responses.
- Detector class: Verifier VF-04
- Target classes: Selected flammables and oxidizers
- Examples: Mineral spirits, acetone and hydrogen peroxide
- Result type: Presumptive two-region color response
Acid Test Demonstration
Screening for Selected Strong Acids
The Acid Test detector is designed to screen for selected strong-acid precursor categories, including sulfuric and hydrochloric acid. The video demonstrates the supplied procedure and representative response.
- Detector class: Acid Test
- Target class: Selected strong acids
- Examples: Sulfuric acid and hydrochloric acid
- Result type: Presumptive colorimetric response
Interpretation Checklist
- Use the current product instructions
- Confirm the detector is within its stated shelf life
- Follow the required sample-preparation steps
- Compare both response stage and color
- Document the sample and operating conditions
What an Example Result Can—and Cannot—Show
Example results help users understand the type of visible response produced by a detector. They cannot establish the performance of every detector lot, sample matrix, environmental condition or interfering material.
Discuss Your Target Materials
Tell ChemSee which explosives or precursors you need to screen, the sample type, operating environment and anticipated volume. We can recommend the appropriate kit or individual detector.
