- Spectral interpretation using reference databases

## Integrated Data Analysis

### Cross-Technique Correlation

```
DSC + TGA:
- Weight loss during melting? → decomposition
- No weight loss at Tg → physical transition
- Exothermic with weight loss → oxidation

FTIR + Thermal Analysis:
- Chemical changes during heating
- Identify decomposition products
- Monitor curing reactions

DSC + FTIR:
- Structural changes at transitions
- Conformational changes
- Phase behavior
```

### Common Material Systems

#### Polymers
```
DSC: Tg, Tm, Tc, curing
TGA: Decomposition temperature, filler content
FTIR: Functional groups, crosslinking, degradation

Example: Polyethylene
- DSC: Tm ~130°C, crystallinity from ΔH
- TGA: Single-step decomposition ~400°C
- FTIR: CH stretches, crystallinity bands
```

#### Pharmaceuticals
```
DSC: Polymorphism, melting, purity
TGA: Hydrate/solvate content, decomposition
FTIR: Functional groups, salt forms, hydration

Example: API Characterization
- DSC: Identify polymorphic forms
- TGA: Determine hydrate content
- FTIR: Confirm structure, identify impurities
```

#### Inorganic Materials
```
DSC: Phase transitions, specific heat
TGA: Oxidation, reduction, decomposition
FTIR: Surface groups, coordination

Example: Metal Oxides
- DSC: Phase transitions (e.g., TiO2 anatase→rutile)
- TGA: Weight gain (oxidation) or loss (decomposition)
- FTIR: Surface hydroxyl groups, adsorbed species
