Latest Patents

Marietta holds a patent for a "Chemiluminescent nitrogen detection apparatus and method." This invention involves a process where a discrete sample of an organic compound is injected into a high-temperature furnace. The sample undergoes pyrolysis in an oxygen-rich atmosphere, resulting in the formation of nitric oxide. The emitted nitric oxide is then mixed with ozone in a reaction chamber, leading to the production of metastable nitrogen dioxide. This process results in a photo-emission of light energy, which is detected by a photo-multiplier tube. The output from this tube is converted into an electrical signal, allowing for the quantitative measurement of chemically-bound nitrogen in the sample.
