Proteins are the main component of insects' meals. There are two standard analytical methods for protein determination
: the Kjeldahl
and the Dumas
1. KJELDAHL METHOD FOR HIGH VERSATILITY
If your lab is analyzing a very wide range of samples, then the Kjeldahl method
is the most suitable choice. Based on traditional wet chemistry, the Kjeldahl analysis is recognized as the traditional technique for protein determination and is a highly versatile method.
VELP offers a Kjeldahl solution for any laboratory need. You can choose from:
◾ fully automatic solutions to free up operator time while ensuring excellent accuracy and precision
>> Discover all VELP automatic digesters
◾ semi-automatic solutions that enable handling a limited number of samples per day, without compromising quality and reliability

2. DUMAS METHOD FOR MAXIMUM PRODUCTIVITY
If your lab needs to keep the highest levels of productivity, then the Dumas combustion technique
, based on innovative dry chemistry, is the most convenient choice.
The Dumas analysis
requires only a few minutes for N/Protein determination
is fully automated and highly reliable. The sample is burnt in a combustion oven to obtain the elemental compounds for the quantitative determination of nitrogen content and protein.
