Rapid Colorimetric Screening with SprayView™
The ChemSee SprayView™ Explosive Detection Kit is a portable surface explosive detection kit for rapid colorimetric screening of nitrate-based explosives. SprayView™ can be applied directly to appropriate suspect surfaces or used with collection pads when residue sampling is preferred.
A key advantage of SprayView™ is the ability to screen large suspect surfaces directly. The detection solutions can be applied to an appropriate surface without first collecting a residue sample. Collection pads are also included when sampling is preferred or direct application is impractical.
SprayView™ provides a visible color response when the applicable explosive chemistry is detected and requires no electronic reader for interpretation.
Standard configurations: 25, 50 and 100 tests
Expanded configuration: SprayView PLUS™ — 50 tests
What Does SprayView™ Detect?
Standard SprayView™ is designed to screen the major nitrate-based explosive groups encountered in military, industrial and security applications.
Nitroaromatics
Colorimetric screening for nitroaromatic explosive materials.
Examples:
TNT • DNT • MNT • Tetryl
Nitrate Esters
Screening capability for nitrate-ester explosive materials.
Examples:
Nitroglycerin • PETN
Nitramines
Visible colorimetric screening for common nitramine explosives.
Examples:
RDX • HMX
Inorganic Nitrates
Screening for nitrate salts associated with explosive and blasting applications.
Examples:
Ammonium Nitrate • Potassium Nitrate • Sodium Nitrate
Direct Surface Screening or Optional Residue Collection
SprayView™ gives the operator flexibility to choose the screening method that fits the surface and application.
Direct Surface Screening
SprayView™ detection solutions can be applied directly to appropriate suspect surfaces, allowing larger areas to be screened without first collecting residue.
Useful for screening:
- Equipment and tools
- Vehicles and cargo surfaces
- Work areas and suspect surfaces
- Mining and blasting environments
- Security and investigative locations
Residue Collection Pads
Collection pads are supplied when an operator prefers to collect material from a surface before applying the detection chemistry or when direct spraying is not appropriate for the item being examined.
Useful when:
- The surface should not be sprayed directly
- A smaller target area is being examined
- Residue needs to be transferred from an irregular surface
- The application calls for sample collection before screening
Important: SprayView™ detection solutions are intended for appropriate suspect surfaces and samples. Do not spray detection solutions on people, eyes, skin or other body parts.
SprayView™ vs. SprayView PLUS™
SprayView PLUS™ retains the large-surface screening format of standard SprayView™ while adding detection capability for selected explosive precursor materials.

Full-Color Instructions
Provides the operating procedure and color-response information used to interpret screening results.
How SprayView™ Works
SprayView™ uses sequential colorimetric chemistry to screen an appropriate suspect surface directly or to test residue collected with the supplied sampling pads. Results are interpreted visually without an electronic reader.
Select
Choose an appropriate suspect surface for direct screening, or collect residue with a supplied collection pad when sampling is preferred.
Apply
Apply the SprayView™ detection solutions in the sequence specified in the supplied operating instructions.
Observe
Watch for the visible color response produced by the applicable detection chemistry.
Interpret
Interpret the result using both the reagent stage at which the response occurs and the observed color, following the supplied reference information.
Typical SprayView™ Color Responses
Positive colors vary depending on the explosive compound being detected. SprayView™ is a sequential test, so both the stage at which a response appears and the resulting color are used when interpreting the screening result.
| Stage | Detection Group | Typical Positive Response |
|---|---|---|
| Spray A |
Nitroaromatics
TNT • DNT • Tetryl • Picric / Styphnic-type compounds
|
Dark green • teal • blue-purple • yellow • orange/red
|
| Spray B |
Nitrate Esters & Nitramines
Nitroglycerin • PETN • RDX • HMX • C4 • Semtex
|
Bright pink • fuchsia • magenta
|
| Spray C |
Inorganic Nitrates
Ammonium Nitrate • Potassium Nitrate • Sodium Nitrate • Urea Nitrate • Black Powder
|
Fuchsia / magenta

Quality Assurance: Supplied validation materials are used as directed to verify that the applicable SprayView™ detection chemistry remains active before or during use.
Screening Use: SprayView™ and SprayView PLUS™ provide rapid presumptive colorimetric screening. Results should be interpreted according to the supplied instructions and the requirements of the application.
Safety & screening limitations: Do not spray SprayView™ or SprayView PLUS™ on people or worn clothing, and do not test suspected devices or unexploded ordnance. A negative screen does not establish safety or authorize clearance, re-entry or blasting decisions. Preserve potential evidence and follow your response procedures and the operating and safety instructions supplied with the kit.
Where SprayView™ Is Used
The direct-spray format is particularly useful when rapid screening of surfaces or larger areas is more practical than testing individual collected samples.
Security Screening
Screen suspect surfaces, equipment, cargo areas and other locations as part of an appropriate security inspection procedure.
Mining & Blasting
Field screening around mining, quarry and commercial blasting operations where nitrate-based explosive materials may be present.
Vehicles & Equipment
Direct screening of suitable vehicle, tool and equipment surfaces when investigating possible explosive contamination or residue.
Field Investigation
Portable screening for military, law-enforcement, investigative and other qualified field applications.
