Residue Sampling Kits

Residue sampling kits are used to collect surface residue and trace contamination using wipes and foam swabs for laboratory analysis. Blue Dragon Defense residue sampling kits provide chemically cleaned, sterile collection materials and chain-of-custody documentation for traceable surface sampling.

How Residue Sampling Works

Residue sampling collects trace material from surfaces, so clean, sterile wipes and swabs are essential to avoid introducing interference. Disciplined technique and documentation keep trace results defensible.

A typical Blue Dragon Defense residue sampling kit includes sterile wipes, macro foam swabs, sample containers, and chain-of-custody forms. Kits range from compact, single-use packs to larger field systems that support multiple samples per mission.

Certified Clean and Sterile

Blue Dragon Defense certifies that its CBRN sampling kits are chemically cleaned and biologically sterile prior to packaging. Preventing external contamination is essential for credible residue sampling, because equipment that is not properly cleaned or sterile can introduce interference that compromises analytical results.

Chain of Custody

Each kit supports documented chain-of-custody procedures — the record of sample control and transfer from collection through shipping and laboratory analysis — so results remain traceable and defensible for regulatory, investigative, and high-consequence operational decisions.
