Nitrogen analysis

Vapodest® (Kjeldahl)

Vapodest® (Kjeldahl)

VAPODEST® is currently the most modern and powerful analysis system on the market for nitrogen analysis using the Kjeldahl method.
VAPODEST® is also ideal for the steam distillation of volatile acids, sulphur dioxide, TVB-N, ammonium, formaldehyde, phenol, alcohol, vicinal diketones or hydrogen cyanide.
Classic distillation apparatus (Kjeldahl)

Classic distillation apparatus (Kjeldahl)

Apparatus for classic, manual Kjeldahl distillation processes with tried and tested C. Gerhardt quality.
Kjeldahl digestion unit

Kjeldahl digestion unit

The successor models KT and KT-L for up to 40 simultaneous Kjeldahl digestions replace the proven digestion system KB and convince with unique product characteristics and functions.

The C. Gerhardt digestion blocks are perfectly adapted to the needs of accredited laboratories and ensure the validity and reproducibility of the analysis results by automating and documenting the process steps.
TURBOSOG fume suction system

TURBOSOG fume suction system

Powerful fume suction washer in tried and tested C- Gerhardt quality for extraction and neutralisation of the inorganic acid fumes created during digestion.
Typically used for digestion with sulphuric acid in nitrogen determination using the Kjeldahl method, digestion with aqua regia (heavy metal digestion) and with perchloric acid/nitric acid (hydroxyproline digestion).

Optimum extraction at exceptionally low operating costs.
With two-stage preseparator for elimination and neutralisation.
Continuously adjustable suction capacity.
Can be combined with all C. Gerhardt digestion units and classic digestion equipment with exhaust manifolds.
Turbotherm rapid digestion unit

Turbotherm rapid digestion unit

Digestion unit with infrared technology. The quick alternative to the KJELDATHERM® digestion block.

Tried and tested C. Gerhardt technology specifically designed for Kjeldahl digestion of a wide variety of samples with nitrogen content in the micro and macro range.

Ideal for subsequent Kjeldahl distillation with the VAPODEST® distillation units.

Also for use as a multifunctional, programmable hotplate for inorganic acid digestion.
