Thank you all for your submissions! 

The correct answer to the Only AMPA Quiz:

There is a problem with reagent #1, the sodium hypochlorite reagent (in CB130). The problems could range from Pump 1 not pumping to no bleach being added. Bleach is required to convert Glyphosate to Glycine, which will react with OPA and Thiofluor. So, if no bleach is present, none of the Glyphosate will be able to react with the OPA and Thiofluor. Only AMPA will be free to react and fluoresce, and your chromatogram will be missing a peak!
