Determination sum of nitrates and nitrites after reduction Devarda´s alloy on the device Kjeltec AUTO 1030.
Determination of nitrates and nitrites are among the main analytical determination in the water. For their determination was drawn up a number of particular. For these samples can easily take advantage of the determination of nitrite

Isoform-specific differences in the nitrite reductase activity of nitric oxide synthases under hypoxia
Nitrite (NO2-) recycling to nitric oxide (NO) is catalysed by a number of enzymes and induces a protective vasodilation effect under hypoxia/ischaemia. In the present work, we tested the in vitro ability of the three NOS (nitric oxide syntha...

Electrochemical Generation of Nitrogen Dioxide for Testing of Gas Sensors
The generation is based on galvanostatic reduction of nitrate to nitrite on Ag cathode. Nitrite is chemically reduced directly in the generation solution to nitrogen oxide which is then oxidized in the stream of air into ni...

Detection, with a pH indicator, of bacterial mutants unable to denitrify
respiring nitrate or nitrite gives rise to a red circular halo. Antimycin blocked these colour changes, which suggests their association with the periplasmic reduction of nitrite. Inhibition of nitrous oxide reductase by a...
