Tlie pesticide results, listed in Table 1,1 are calculated by using the following forninJa:
Cu - (DF)(Au)(Vt)
(RFavc)(ViXW)(D)
where,
C. = ConccniruKon of anaiyle (wg/kg)
DF = Dilution Factor
A. - Area or peak height
V. “ Volume of sample (mL)
- Average lespottsc factor
Vi - Volume of extract injected (pL)
w = Weight of sample (g)
D = Decimal percciU solids
Response Factor calcuhtion;
The response factor for each specific analyte is calculated using ilic peak area (peak height) from the
continuing calibmiion check ns follows;
Au
jyr a --------------------
Iola I pg injected
where;
A,, ' Area or peak hdghl
And
