SECTION 1 GENERAL DESCRIPTION
1.1 Introduction
The Hach Digesdahl Digestion Apparatus shown in Figure 1 is designed
to digest a wide variety of sample types for subsequent determination of
total Kjeldahl nitrogen, several minerals, and nutrients. Sample types
include food products, feeds, grains, wastewater sludges, plating baths,
plant tissues, fertilizers, beverages, and oils.
Digestion takes a fraction of the time required for traditional methods.
The digest is used with colorimetric, turbidimetric or titrimetric
procedures for final measurements. Digesdahl test results compare
favorably in accuracy and precision with those obtained by traditional
analytical methods.
