The phrase "and quantitated using a" is not correct in standard written English; the correct term is "quantified." You can use it in contexts where you are describing a method of measurement or analysis in scientific or technical writing.
Example: "The samples were analyzed and quantified using a spectrophotometer."
Alternatives: "and measured using a" or "and assessed using a".
