Modifying PTR-MS operating conditions for quantitative headspace analysis of hydro-alcoholic beverages. 2. Brandy characterization and discrimination by PTR-MS

- High E/N value has a limited impact on VOC fragmentation patterns.
- Brandies were discriminated the same way using E/N values of 145 Td or 454 Td.
- Discriminating ions between brandies were different between the two operating conditions.
- Ions that discriminate brandies could be more likely related to VOCs at 454 Td.
