Interview Questions for Scientific Equipment Operation

Calibration is crucial for ensuring the accuracy and reliability of scientific instruments. It involves adjusting the instrument to provide readings that match known standards. My experience encompasses calibrating a wide range of instruments, from simple balances to sophisticated spectrophotometers. For example, when calibrating an analytical balance, I would use certified calibration weights to establish a baseline. This involves placing weights of known mass on the balance and adjusting its internal settings until the displayed value precisely matches the weight’s actual mass. This process often involves multiple weight calibrations spanning different mass ranges to check for linearity. For spectrophotometers, the process includes using certified standards with known absorbance values at specific wavelengths, verifying the instrument’s accuracy against these standards and then adjusting the instrument to compensate for any deviations, documenting everything meticulously in a calibration logbook. This logbook ensures traceability and compliance with laboratory quality standards. For more complex instruments like HPLC, calibration might involve running standards of known concentrations and adjusting parameters to achieve the expected peak areas and retention times. Each instrument has its unique calibration procedure, and adherence to the manufacturer’s guidelines and maintaining detailed records are paramount.

Troubleshooting a malfunctioning HPLC (High-Performance Liquid Chromatography) requires a systematic approach. I typically start by observing the problem. What is the exact nature of the malfunction? Are there errors displayed on the instrument’s screen? Are the peaks distorted, absent, or show unusual retention times? Once I’ve identified the problem, I follow a structured approach:

• Check the basics: Ensure the solvent reservoirs are filled with the correct solvents, and that the pumps are primed. Check tubing connections for leaks or blockages. Verify the detector is working by running a known standard. A simple visual inspection can frequently identify the source of the problem.
• Inspect the column: A faulty or contaminated column is a common culprit. Look for signs of clogging or damage. The column might need replacement or regeneration.
• Examine the system’s data: Review the chromatograms to pinpoint the issue. For example, broadened peaks could indicate column problems, while reduced sensitivity could signal detector issues. Pressure fluctuations might indicate pump issues or system leaks.
• Investigate the software: Ensure the method parameters are correctly entered. Software glitches can also cause malfunctions.
• Consult documentation: Manufacturer documentation and troubleshooting guides should always be the first point of reference. These guides often provide step-by-step solutions.

If the problem persists after these steps, I may need to contact the instrument manufacturer’s technical support for more advanced troubleshooting.

Accuracy and precision in spectrophotometry are paramount for reliable results. We achieve this by focusing on several key areas:

• Proper instrument calibration: Regular calibration using certified standards with known absorbance values at specific wavelengths is essential. This ensures the instrument is reading correctly. Think of this as ‘zeroing’ the instrument – a necessary step before any accurate measurements can be taken.
• Blanking the spectrophotometer: Before each measurement, a blank solution (a solvent without the analyte) is used to establish a baseline. This corrects for any absorbance from the solvent itself. The blank corrects for background noise.
• Using appropriate cuvettes: Clean, matched cuvettes (the small containers holding the samples) are essential. Any scratches or impurities in the cuvettes can affect the absorbance readings. Matching cuvettes ensures consistency in light path length across readings.
• Maintaining the sample temperature: Temperature changes can influence absorbance readings, particularly for some substances. Temperature control measures can be employed if temperature-sensitive samples are being analyzed.
• Appropriate sample preparation: Preparing the sample accurately is equally as important as the instrumental aspects. Accurate dilutions, proper mixing, and removal of particulate matter are key. We ensure the solution is homogeneous.
• Multiple measurements and statistical analysis: Taking multiple measurements of the same sample and calculating the average helps account for random errors and assess the precision of the measurements. Statistical analysis provides more confidence in the obtained results.

By consistently implementing these procedures, I can reliably maintain the high standards of accuracy and precision needed for my work.
