Kjeldahl Steam Distillation – Fully Automatic Pro-Nitro A
Overview
Similar to the Tecator Kjeltec 2300 and 2400, Pro-Nitro A is used for the automatic determination of organic nitrogen (Kjeldahl Method). The system is complete with automated “ON-LINE” analysis (evaluation in real time). The titration is a colorimetric method and is accepted by AOAC and does not require any periodic calibration.
The Kjeldahl steam distillation unit – Pro-Nitro A evaluates the distillate at the same time as it is produced. The evaluation and distillation are completed as one operation, reducing drastically the analysis time. This type of evaluation offers the following additional advantages: detect the point where the sample no longer produces Nitrogen, which means that the distillation stops at the optimum maximum Nitrogen recovery and does not prolong the analysis longer than necessary.
Features of the Pro-Nitro A Kjeldahl Steam Distillation unit:
Distillation by steam generation
Automatic «On-line» colorimetric evaluation
Steam generator with safety thermostat, over temperature and over pressure device
Safety: Door closed, that prevents distillation if open
Universal adapter for MACRO (Ø 42 mm) and MICRO (Ø 26 mm) distillation tubes
Detects that a digestion/distillation tube is present; this prevents the dosing of NaOH if there is no tube located
Space saving in the laboratory: the reservoirs for the H2O, NaOH, Boric Acid and HCl are located inside the unit
Empties the digestion/distillation tubes and the collector automatically
Automatic stops when distillation is complete
Large LCD display of 16 x 4 characters
RS232 output to results printer
