Chemical Identification Tools: Raman, FTIR, and Tubes

How field identification tools support hazmat teams without replacing sampling discipline, reference libraries, or lab confirmation.

Selection guide, not an endorsement. Equipment choices must follow department risk assessment, applicable standards, manufacturer instructions, fit testing, maintenance records, calibration policy, and technician training.

Field Use

Chemical identification tools can narrow a mystery, confirm shipping papers, support product control, and guide protective actions. They do not make a hazardous sample harmless, and they do not remove the need for PPE, decon, chain of custody, or lab confirmation when required.

Raman, FTIR, colorimetric tubes, pH paper, test strips, and reference databases each have strengths and blind spots. Good programs buy the tool, the library, the training, the sampling procedure, and the quality-control process together.

Tool Comparison

RamanCan identify many solids/liquids through some containers; fluorescence, mixtures, dark containers, and safety limits can interfere.
FTIRStrong for many liquids, solids, and unknowns with direct sample contact or accessory methods; library quality matters.
Colorimetric tubesTargeted gas/vapor screening with known tube chemistry; cross-sensitivity and pump technique affect results.
pH / stripsFast acid/base or oxidizer clue, not a full product identification.

Purchase Questions

  • What sample states, containers, mixtures, and concentrations can the tool handle?
  • How often are libraries updated, and can results be exported for documentation?
  • What PPE, sampling, decon, and evidence procedures are required?
  • How does the tool perform in sunlight, smoke, weather, cold, and with gloved hands?
  • What training hours and recurring competency checks will the department fund?

Do Not

  • Do not open unknown containers just to get a better reading unless a trained plan supports it.
  • Do not treat a library match as lab confirmation when legal, medical, or cleanup decisions require stronger proof.
  • Do not forget that mixtures, contamination, packaging, and fluorescence can mislead instruments.
  • Do not separate the device purchase from sampling tools, PPE, decon, and documentation.

FAQ — Chemical ID

Neither is universally better. Raman can read through some containers; FTIR is strong for many direct-contact samples. The right choice depends on mission profile, sample types, libraries, training, and budget.

Yes. Tubes can be simple, targeted, and useful when the suspected chemical is known, but they require correct tube selection, pump technique, and cross-sensitivity awareness.

Verify the equipment purpose, detection or protection limits, training requirements, calibration or inspection status, maintenance records, compatible accessories, replacement parts, and how the tool fits the department SOP/SOG.

Keep purchase specifications, certification or approval documents, training records, inspections, calibration or bump-test logs where applicable, repairs, failed checks, and post-incident notes showing how the equipment performed.
