Presumptive Screening for PETN Residues and Samples
Pentaerythritol tetranitrate (PETN) is a nitrate-ester high explosive used in detonating cord, boosters and some plastic-explosive formulations. ChemSee provides direct-visual screening formats for controlled surfaces, portable field work and repeated sample programs.

Screening Context
PETN-class detection is useful when a trained team has a properly collected residue or an authorized material sample. Product choice depends on whether the need is surface mapping, portable multi-target screening, aviation readiness or higher sample volume.
- Target class: nitrate-ester explosive
- Readout: visible color response
- Use: presumptive field screening
- Escalation: follow the applicable SOP and confirm when required
Nitro-Pen / EXPKIT
Individual or multi-target portable screening of collected residues and material samples.
Nitro-Screen / IFED
Higher-volume screening or a compact aviation-oriented configuration.


Interpret Example Responses Carefully
Archived images demonstrate the type of visual response that may occur. Color and intensity can vary with matrix, loading, lighting, detector condition and procedure; a demonstration does not establish performance for every real-world sample.
