[top] To separate Nitrite from Chromate in Urine, it is recommended to use CElixirOA 2.5 in reverse polarity with indirect detection mode on your instrument. The signal should be analyzed at 214nm. 10. I have been successfully using CElixirOA for the separation of Nitrite from Nitrate. After a day or do, I begin to lose one of my peaks. What could be the cause of this? When I use fresh sample, I have two peaks again. [top] The answer may be that your Nitrite peak is degrading into Nitrate which is normal. Fresh sample must be used if this is what is happening.
