Determination of total protein content:Determination of Kjeldahl nitrogen
The behr equipment for determination of Kjeldahl nitrogen offers the user a complete individually configurable solution for the laboratory.
• Sample Digestion Units
The sample digestion units of the behrotest® InKjel line are provided withpowerful infra-red heating elements.
The quality and positioning of the infra-red heating elements guarantee the user reproducible heating phases and digestion temperatures at all sample positions. This also pertains to the twelve sample digestion unit, in which the samples are arrayed in two rows of six each.
Direct irradiation of the samples by the infra-red sources eliminates the pain-fully slow warm-up phase associated with conventional heating block units.
Thus, the behrotest® InKjel is the ideal rapid digestion unit for the Kjeldahlnitrogen determination and other high temperature sample digestions.
• Steam distillation units
The behr steam distillation units of the „S“ model series are the optimalcomplement to the InKjel rapid digestion units.
Depending on the user’s requirements, he may choose between one manual and two automatic steam distillation models. These are similar in concept, but differ in the level of automation and convenience features. The top-of-the-line model, the behr S 5, is designed to accept an external titrator.
All behr steam distillation units have the following common features:— Powerful and fast— Practical and user-friendly— Exemplary safety and reliability— Sturdy chemically resistant stainless steeel housing— Practical quick-release vessel clamp permits easy use with right or left hand— Especially simple menu-driven operation of the programmable apparatus by means of one single control knob
• Fume exhaust system
The two-stage behrosog fume exhaust system – condensate trap plusneutralization stage – keeps all acid fumes completely out of the environment.
• Titration stations
The behrotest® STI manual titration station or an automatic titrator provide for reliable, safe and rapid titration into complete the nitrogen determination.

behrotest® InKjel Infra-red Rapid Digestion UnitsThe basic units in the behrotest® InKjel model series hold insertable frames for different combinations of vessels:
• 6 reaction vessels with 250 ml capacity in InKjel 625 (M or P)
• 12 reaction vessels with 250 ml capacity in InKjel 1225 (M or P)
• 4 reaction vessels with 500 ml capacity in InKjel 450 (M or P)
• 4 reaction vessels with 750 ml capacity in InKjel 475 (M or P)
If required, the user can re-equip his system himself very easily with different digestion boxes (insertable frame with suction extraction apparatus) for other sample glassware.
The behrosog process suction system is available to extract vapours during digestion.
All InKjel systems are completely equipped with tiered console, suction system, insertable frame and digestion glass vessels.

Acid Digestion – Sample Preparation for Extraction
Extraction following Acid Digestion –The Weibull-Stoldt Method
The quantitative determination of the fat content in food is performed by means of a solvent extraction. The “free fat” is de-termined by direct extraction. The “total
fat” content is composed of the sum of the “free fat” and the “bound fat,” which is released by the acid digestion.
