For systematic precise analysis, with minimum personnel intervention, simple and safe. Adequate for a laboratory with a medium to large throughput of samples.
The Kjeldahl steam distillation unit «PRO-NITRO A» evaluates the distillate at the same time as it is produced ( evaluation «On-Line»), the evaluation and distillation are completed as one operation, reducing drastically the analysis time. This type of evaluation offers the following additional advantages: detects 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.
The titration is a colorimetric method and is accepted by AOAC and does not require any periodic calibration.
