Abstract A rapid paper spray (PS) ionization tandem mass spectrometry analytical method has been developed to determine multiple pesticides in red wine. Without chromatographic separation, 36 pesticides in wine could be simultaneously determined less than 9 and 3 min, followed by off-line QuEChERS treatment and on-line paper adsorption treatment, respectively. Isotopically labeled internal standard (IS) was utilized to calibrate injection process, and linear ranges were one to three orders of magnitude for different pesticides. LODs were ranging between 0.1 and 100 ng/mL, and LOQs were ranging between 0.3 and 300 ng/mL. Method validation was used to evaluate the accuracy and precision, and the results for most analytes were at the range of 75– 120%. All the data processes were automatically achieved by build-in instrument software. These methods were also compared with QuEChERS-DART-MS/MS and DART-MS/MS. The results demonstrated that PS-MS/MS was a rapid and simple method to quantify multiple pesticides in red wine. Keywords Automatically high-throughput quantification . Paper spray (PS) ionization .

Introduction Pesticides are utilized in vineyards to protect wine grape from diseases derived from fungi, insect, acarid, herb, and itself (Carpinteiro et al. 2010). However, overdose, overrange, and untimely abuse of pesticides may affect the quality of wine grape and cause residue on the surface of grape. Considering that wine is fermented by grape, the residual pesticides in grape would probably be transferred to the final wine and have an adverse effect on wine quality and even consumer health (Pelajic et al. 2016). However, the events of pesticide residue in wine frequently occurred.

Europe reported that all the wines were found having pesticides, which totally involved 24 pesticides and eight countries. Even some pesticides were classified as being carcinogenic, mutagenic, reprotoxic, or endocrine disrupting by European Union (Pesticide action network (PAN) Europe. Message in a Bottle 2008). On the other hand, regulatio
