Optimizing Kjeldahl Digestion: Eliminating Thermal Gradients in Block Digesters
Precise nitrogen determination hinges on uniform thermal transfer across every sample vessel. Analytical chemists handling nitrogen and crude protein assays frequently observe erratic recovery rates across multi-tube batches. Digestion vessels positioned along the outer edges of traditional heating blocks lose heat to ambient laboratory air much faster than interior positions, creating severe thermal gradients. Thermal […]
