Primary Amino Nitrogen UniTab Reagent (=PAN): Determine primary amino nitrogen compounds (or Nitrogen by OPA = NOPA) in grape juice & fermenting wine/must samples.

Contains buffered N-Acetyl-l-cysteine (NAC) tablets, ophthaldialdehyde (OPA), and Nitrogen Standard Solution.

Each tablet is dissolved in 5 mL of deionized water, permitting the user to prepare only as much working reagent as required for daily use. This “fast blanking” method only requires working reagent (the blank reagent solution is no longer required). This procedure is based on a published method from UC Davis.
