Specializing in Exotic Sampling

Including TRS, NMOC, Cl/ClO₂, HAPS & Reactive Compounds

Where complex reactive compounds are present, Valid Results' years of field experience always pays off, yielding the most accurate and repeatable results possible.

Valid Results recognizes the reactivity between SO₂, ammonia and temperature, affecting systems where ammonia injection is used to control nitrogen oxide emissions, and the measurement of sulfur dioxides are required.  Thus, precise temperature controls and a complex hot ammonia removal system enable accurate SO₂ measurements.
