5 | P a g e
It supplies the reactor solution to the reaction coil.
5. Reactor Backpressure Coil
It maintains high enough pressure that the reactor pump can work efficiently.
6. Manual Injector (and/or Autosampler)
Manual injection of up to 50 µL of sample using a blunt ended Hamilton syringe can be made
here.
7. Mixer
Mixes the column effluent with the Reactor solution before entering the reaction coil.
8. Reaction Coil
Gives time for the reaction to be heated and go to completion. It also helps to reduce mixing
noise.
9. Detector Cell
Detects absorbance at 540 nm.
10. Separation Column
Separates the Nitrite and the Nitrate from other biological compounds.
11. Reduction Column
Reduces the Nitrate to Nitrite so that it can react with the Greiss reagent.
