Measurement-First Technology for Defense

BSI's Data-Logging Breath Analyzer (DLSIB) is a portable instrument that measures exhaled nitric oxide, oxygen, and carbon dioxide alongside breath flow, temperature, and humidity. For defense, that combination is a window into respiratory readiness — screening airway inflammation, tracking response to exertion and altitude, and monitoring recovery without a lab.

Because it logs data continuously in a field-portable form factor, DLSIB fits human-performance and readiness programs that need objective respiratory metrics on operators rather than a one-time clinic reading. See the DLSIB breath analyzer page.

Two complementary detection paths. BSI's compact FT-ICR mass spectrometer resolves hydrogen and helium isotopes at R > 10,000, separating He-3 from HD and HT from D₂ — the isotope discrimination behind tritium accounting and treaty-relevant gas analysis that quadrupole RGAs cannot deliver.

For particle detection, CR-39 solid-state track detectors passively record neutrons and alphas. BSI has imaged 14 MeV neutron-induced proton-recoil and U-238 fission-fragment tracks and classifies them with peer-reviewed SEM large-area mapping and AI analysis. Boron-coated variants add thermal-neutron sensitivity via the ¹⁰B(n,α)⁷Li reaction.

The same CR-39 detector doubles as a passive dosimeter. Worn as a badge, it records cumulative neutron and charged-particle dose in reactor and accelerator facilities, weapons and material-handling environments, and field operations — no batteries, no electronics, and a permanent etched record that can be re-read and audited later.

BSI supplies the detectors, boron coating for neutron work, and full etching-plus-analysis service, or the equipment and training to process in-house. See neutron-sensitized CR-39 and passive neutron detection.

BSI manufactures nuclear-grade CR-39 in the United States, so federal, national-lab, and defense-contractor programs work with a US-based technical team from quote to delivery. Beyond catalog detectors, BSI develops custom sensors, electronics, and software — the same measurement-first approach applied to program-specific instrumentation. See the American CR-39 manufacturer page.
