- Fill the Eluent Reservoir: Use suitable eluents that are compatible with the analysis being performed.
3. Calibrate the Instrument
- Run Calibration Standards: Use known concentrations of standard ionic solutions to calibrate the ion analyzer.
- Adjust Settings: Set the optimal flow rate, temperature, and other parameters specific to your setup.
4. Perform the Analysis
- Inject the Sample: Carefully introduce the prepared sample into the system.
- Monitor the Readings: Keep an eye on the detector's response as the sample is processed over time.
5. Interpret Results
- Analyze Chromatograms: Assess the output chromatograms to identify and quantify ions present.
- Check Against Standards: Compare peak areas or heights with calibration data for quantification.
6. Maintain the Instrument
- Regular Cleaning: Perform routine maintenance, including cleaning of the injection port and detectors.
- Replace Consumables: Keep an inventory of necessary parts, such as columns and filters, to ensure optimal performance.
