  • quantify: Stringent internal quality control procedures were adopted to identify and quantify PCBs congeners in both packaging and food.

Adjective modifier

  • specific: However, such analysis would be prohibitively costly so specific congeners are selected for analysis, including those which are toxicologically significant 10.
  • most: The use of upper bound estimates may significantly overestimate total dioxins concentrations in those samples where most congeners are not present at the LOD.
  • full: Full congener specific data are available in the final contractor's report of the survey.

Modifies a noun

profile: Samples which were not as described on the bottle had congener profiles clearly differing from those supplied by the manufacturers for their products.

Noun used with modifier
