Crude Protein Determination by Kjeldahl

Check if the same lab product or an alternative is used in the 5 most similar protocols
Crude protein was determined by weighing out ~0.25 g of sample and adding 5 mL sulphuric acid (analytical reagent grade, Fisher Scientific, Loughborough, UK) together with 2 copper catalyst tablets (Fisher Scientific, Loughborough, UK), before digesting at 400 o C for 1 h (Foss Digestor 2040; Foss Analytical AB, Högnäs, Sweden). Total nitrogen levels were measured by Kjeldahl (Foss Kjeltec™ 2300, Foss Analytical AB, Högnäs, Sweden) and the crude protein level calculated as N  6.25.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
