Description

General description

The glycine standard is produced under stringent conditions and measured with the highest possible precision.

Application

It can be used as an analytical standard to:

• Evaluate Kjeldahl′s procedure to determine total protein content of reference standards used in clinical laboratories.
• Analyze beer and wine for their protein and total usable nitrogen using a microwell ninhydrin assay.
• Compare Kjeldahl and Dumas methods for routine analysis of dairy products in an interlaboratory study.
• Simultaneously determine total phosphorus and total Kjeldahl nitrogen in surface water samples.
• Quantitatively determine nitrate in surface waters using Valdetrama method.
• Measure low level Kjeldahl nitrogen using an AutoAnalyzer.
