Transcribed Image Text:# Chromatogram Analysis
### Description:
The chromatogram displayed above is a graphical representation of a sample analysis using chromatography.
### Key Features:
- **Axes:**
- The x-axis represents time in minutes (min), ranging from 0 to approximately 2.5 minutes.
- The y-axis represents the signal intensity in microvolts (uV), ranging from 0 to 30,000,000 uV.
- **Peaks:**
- Two significant peaks are visible in the chromatogram.
- The first peak appears at approximately 0.97 minutes with a high intensity.
- The second peak appears at approximately 1.72 minutes with a lower intensity than the first.
### Interpretation:
- **Retention Time:**
- The time taken for a compound to travel through the chromatographic system is referred to as the retention time, indicated by the peaks at 0.97 min and 1.72 min.
- **Signal Intensity:**
- The height of the peaks corresponds to the concentration or amount of the compound present in the sample.
### Usage:
Chromatograms are used extensively in analytical chemistry to separate, identify, and quantify each component in a mixture. The data helps in understanding the composition and purity of a substance.
### Notes:
- The label "SFID1" is likely an identifier for the sample or the chromatographic run.
- Accurate interpretation depends on standardized conditions and calibration with known standards.
This chromatogram provides detailed insight into the sample composition and is an essential tool for quality control and research applications in various scientific fields.
Expert Solution
Step 1: Introduce GC concept
Gas chromatography is a method of separating and identifying components of a mixture.
It depends on intermolecular forces of attraction present in a molecule which determines boiling point of a compound.
