ENO-20/30
The negative peak is caused by the change in matrix from the carrier to the sample. There is almost always a negative peak and this is normal. However, an a...

ENO-20/30, Smaller Peak (small peak, less signal, weak signal) with Standard for Nitrite and Nitrate
1. Inject 10 µl of 10 µM standard from the manual injector, mix nitrite and nitrate. When using the manual injector, please set the autosampler injector at ...
