Hi, @MRiccio,

If you mentioned the ATNA, the following thread is helpful. And @Andrew.James will kindly help you. He is a professional in this field.

Automated Total Nitrosamine Analyser

Sample Preparation Some sample types can be added directly to the sample vial; others may require extraction into a solvent first. Once in the sample vial, the Reagent can be added, the vial sealed and then loaded into the autosampler. Automated Chemical Reaction Process The samples are vortexed and then heated.
