What these specifications mean

The unit provides a measuring range of 0.1 to 200 mg N. Its recovery exceeds 99.5% at nitrogen levels from 1 to 200 mg N. This supports quantitative nitrogen determination across most of the stated measuring range.

Distillation takes 4 minutes at 30 mg N and 7 minutes at 200 mg N. The 30 ml/min distillation capacity and these times define sample processing speed at the stated nitrogen levels. Reproducibility is 1% RSD, including the digestion step, so the repeatability figure covers both digestion and distillation.
