Semi- auto Nitrogen Analyzer
 
  Instrument Details  
 
Make : Kel-Plus
Model : Classic DX
Specification :Estimation of nitrogen in soil and plant   samples 

 
  Working Principles   

The easily mineralizable nitrogen is estimated using alkaline KMnO4, which oxidizes and hydrolyses the organic matter present in the soil. The liberated ammonia is condensed and absorbed in boric acid, which is titrated against standard acid. The method has been widely adopted to get a reliable index of nitrogen availability in soil due to its rapidity and reproducibility. The process of oxidative hydrolysis is, however, a progressive one and thus, a uniform time and heating temperature should be allowed for best results. Use of glass beads checks bumping while liquid paraffin checks frothing during heating as is recommended in total N estimation by Kjeldahl method.
