SMS‑TW‑01 Explosive & Precursor Detection Reagent Kit

Description

SMS‑TW‑01 combines a set of specially formulated colorimetric reagents, sampling tools and consumables in a rugged carrying case to support fast, targeted, on‑scene qualitative identification of conventional and improvised explosive substances and their precursors. The kit uses established chemical color‑change reactions tailored to interact with specific functional groups found in chlorates, perchlorates, nitrates, peroxides, nitroaromatics (TNT/DNT/PNT), nitrate esters (NG), nitramines (RDX/HMX), fuel components (gasoline/kerosene/diesel), oxidizers (KMnO₄), TATP/HMTD/DADP types, and many other reagents. Designed for non‑laboratory environments, SMS‑TW‑01 supports quick tactical decisions, compliant sample packaging and secure evidence handling for downstream laboratory confirmation.

Key Features:

• Rapid single‑step sampling and readout — visual result in ≤5 seconds.

• Broad detection coverage — 20+ explosive compounds and common precursors (oxidizers, peroxides, nitrate/nitro compounds, fuel residues, etc.).

• High sensitivity — microgram‑level detection (typical <50 µg).

• Robust environmental tolerance — reliable operation across 5–40°C and resilient to humidity, dust and common adulterants.

• Field‑ready kit layout — reagents, color‑change papers, gloves, spatulas, tweezers, sample bags and illustrated SOPs organized for fast use.

• Evidence‑centric — tools and packaging enable on‑site extraction, sealing and chain‑of‑custody compatible storage.

• Long shelf life and repeatable use — designed for many tests with stable reagents and clear expiry labeling.

• Simple operation — minimal training required; color charts and stepwise instructions provided.

Application Range:

• Security screening at large events, transport hubs and checkpoints.

• Crime scene and forensic preliminary screening for explosive residues.

• Anti‑smuggling inspections, logistics and parcel checks.

• On‑site verification in bomb disposal, emergency response and industrial security.

• Rapid triage prior to laboratory confirmatory analysis.

Technical Specifications / Parameters:

• Model: SMS‑TW‑01

• Detection principle: Chemical colorimetric (qualitative) reactions specific to target analytes

• Detectable classes (examples): chlorates, perchlorates, nitrates, nitrites, sulfur, ammonium salts, TATP/DADP/HMTD (peroxide explosives), nitroaromatics (TNT/DNT/PNT), HMX, RDX, PETN, nitroglycerin, fuel residues (gasoline/kerosene/diesel), KMnO₄ and other oxidizers — overall 20+ substances and derivatives.

• Sensitivity: microgram‑level (typical <50 µg)

• Result time: immediate; visual within ≤5 seconds after reagent application

• Working temperature range: 5°C to 40°C (usable −5°C to +40°C in storage/transport)

• Interference resistance: High — formulated to tolerate common adulterants, humidity and dust

• Reagent lifetime (shelf life): ≥18 months (depending on storage)

• Estimated uses per kit: designed for multiple field tests (usage count varies by configuration)

• Kit components (typical): rugged carrying case, specialized reagents, colorimetric papers/cards, disposable gloves, spatulas, tweezers, sample extraction tools, evidence seal bags, instruction manual with color charts and SOPs.

Operation & Evidence Handling:
Follow the included illustrated SOPs: collect a representative sample (swab/solid/liquid as instructed), apply the appropriate reagent to the test paper or sample, observe the color change against the reference chart, package and seal any presumptive positive material in provided evidence bags, complete the record form and send sealed samples to a laboratory for confirmatory testing if required.

Safety & Limitations:

• The SMS‑TW‑01 provides presumptive qualitative results only. Positive field tests require laboratory confirmation (instrumental analysis) for legal evidentiary use.

• Operators should follow PPE guidance in the manual; avoid inhalation or direct contact with reagents.

• Extremely unusual matrices or heavily contaminated samples may require modified sampling or lab prep.
