Method synopsis

Fluorometric analysis of ammonia in water samples using working reagent that produces fluorescent compound when reacting with ammonia. Uses quadruplicate sampling and background correction.

Synthesized from method descriptions across 12 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — High interspecific variation in nutrient excretion within a guild of closely related caddisfly species (2018), Ecosphere. Implementations in other papers (listed below) may differ.

1. Ammonium analysis
   Ammonium was measured for each excretion sample using quadruplicate 20 mL filtered water samples using a Turner Designs Trilogy Fluorometer following the fluorometric method. The method uses standard additions to determine a precise and matrix-corrected concentration of NH4+-N.
   Quantities: Quadruplicate 20 mL samples per measurementDuration: Laboratory analysis conducted after field seasonConditions: Standard laboratory conditions for fluorometric analysis
   Equipment: Turner Designs Trilogy Fluorometer
