Sample interview questions: How would you handle the calibration of an atomic spectroscopy instrument?

Sample answer:

Calibration of an Atomic Spectroscopy Instrument

1. Establish Traceability: Ensure the instrument is calibrated using certified reference materials or primary standards traceable to national or international standards. This establishes the accuracy and reliability of the measurements.

2. Perform Regular Calibrations: Determine the appropriate calibration frequency based on instrument usage, sample matrix, and analytical requirements. Calibrations should be performed regularly to maintain instrument performance and ensure accurate results.

3. Use Appropriate Standards: Select calibration standards that represent the range of analytes and matrices expected in the samples. Standards should be prepared using high-purity reagents and certified values.

4. Optimize Instrument Parameters: Adjust instrument settings such as lamp intensity, resolution, and wavelength to achieve optimal signal-to-noise ratio and accuracy.

5. Create Calibration Curves: Collect data for a series of calibration standards and use statistical methods (e.g., linear regression) to determine the relationship between the measured signal and analyte concentr… Read full answer
