## 3 Results and Discussion
### Analysis of Samples  
The proposed method was employed for the analysis of 16 samples (jellies, hard candies and lollipops). The results for the examined analytes that were quantified in the jellies are summarized in Table 6, while the results for hard candies and lollipops are summarized in Table 7. \begin{table}
