文摘

Multiple internal standard normalization improves the VOCs quantitation in VOOs. The choice of a suitable ISTD is crucial for a correct quantitation of VOCs in VOOs. A unique identification of all VOCs and ISTDs was achieved by suitable ion extraction. Method validation was carried out by studying quality parameters for 71 VOCs. Two LVOOs and nine EVOOs were analyzed to check the performance of the method.
