Determination of penconazole on personal protection equipment after field applications.
A simple analytical method, validated in-house and intra-laboratory, has been developed for the determination of penconazole on personal protection equipment (PPE) used by operators during field applications of Topas 20EW. The analytical determination of penconazole was performed by GC- ECD. Sample preparation was based on a liquid extraction procedure. The possible effect of different personal protection equipment matrices on the analytical determination of penconazole was studied and evaluated with regression analysis. No evidence of significant (at 95% CI level) effect was observed at several fortification levels. The percentage recovery of penconazole from the different PPE was in the range 59-100% with adequate correlation with the level of fortification (r2>0.99). The RSD% was in the range of 1-15% and the LOD and LOQ for penconazole were 0.84 and 2.5 ng mL(-1), respectively.[1]References
