An evaluation of the Waters Pico‐Tag system for the amino‐acid analysis of food materials

Abstract

The Pico-Tag method, recently described by Heinrikson and Meredith and developed commercially by Waters Associates, is an integrated technique for amino-acid analysis. Phenylisothiocyanate (PITC, or Edman’s reagent) is used for pre-column derivatization, while reversed-phase gradient elution high-performance liquid chromatography (HPLC) separates the phenylthiocarbamyl (PTC) derivatives which are detected by their UV absorbance. Figure illustrates the chemistry of the derivatization reaction. Cohen, Tarvin and Bidlingmeyer [2] from Waters Associates have reviewed the potential of the Pico-Tag method.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
