【實用教育app】Kjeldahl Optimizer|最夯免費app

Calculate optimized digestion and distillation parameters for the nitrogen determination according to Kjeldahl. The calculator outputs the following digestion parameters:

- Number of Kjeldahl Tablets (or weight of powder)

- Volume of sulfuric acid

Distillation parameters

- Volume of water for dilution

- Volume of sodium hydroxide for alkalization

Titration parameters

- Titrant consumption for blanks

- Titrant consumption for the sample

- Calculated nitrogen amount per sample tube

It also contains helpful information to other parameters such as the digestion and distillation time, pH and volume of the boric acid and the steam power.

The calculation is based on manifold process inputs. Tables, graphs, tips and literature references help to understand the theoretical background but also the practical consequences of the following actions:

- Boric acid concentration

- Sample tube size

- Type of distillation (direct vs. standard Kjeldahl)

- Type of catalyst (Tablet type vs. powder)

- Titrant normality

- Sample type and amount
