Ripening, of course, eventually leads to spoilage, so there are important commercial reasons to increase and control post-harvest longevity. Complicating matters, post-harvest longevity varies naturally. Strawberries, for example, last…

Pushing The Limits Of Hydrazine Detection At NASA

Ever since Interscan developed a portable hydrazine analyzer for Brooks Air Force Base, way back in the late 1970’s, our instruments have been widely deployed in all facets of hypergol (pertaining to fluid propellant) fuel and oxidizer measurements. A new wrinkle was brought in when NASA requested an instrument with 10 parts-per-billion (ppb) sensitivity. Here…
