Basic principles and terms
- Elemental Analysis (EA) is an analytical technique used for determination of elemental composition of various samples. The contents of common elements (C, H, N, O, S) are determined by various methods.
- One of the methods of the Elemental Analysis is combustion of the sample and separation of the products by gas chromatography techniques.
- Dedicated instruments called Elemental Analyzers are commercially available.
- Analytical Balance are widely used with Elemental Analyzers. Clarity with EA Extension can automatically transfer the weight from the balance to the Sequence Table.
EA-specific terminology
Some of the information fields on the Method Setup - Measurement and Chromatogram - Measurement Conditions tabs were renamed to better match the EA terminology.
Renamed existing informational fields:
| Default mode | EA mode |
|---|---|
| Column | GC Column |
| Mobile Phase | Oven Temperature |
| Pressure | Left Furnace Temperature |
| Temperature | Right Furnace Temperature |
