Capillary Electrophoresis
Capillary Electrophoresis is a laboratory method used to separate and analyze different molecules, particularly DNA, proteins, and other biological compounds. Think of it as a highly precise sorting system that helps scientists identify and measure different components in a sample. It's like having a very sophisticated filter that can separate different ingredients in a mixture. This technique is commonly used in genetic testing labs, pharmaceutical companies, and research facilities. Similar methods include gel electrophoresis or high-performance liquid chromatography (HPLC). When you see this term in a resume, it indicates that the candidate has experience with detailed laboratory analysis and precise measurement techniques.

Example Interview Questions
Senior Level Questions
Q: How would you troubleshoot poor resolution in CE analysis?
Expected Answer: A senior analyst should explain the systematic approach to identifying issues, such as checking buffer conditions, sample preparation methods, and instrument maintenance status. They should mention previous experience solving similar problems.
Q: How do you validate a new CE method?
Expected Answer: Should discuss creating standard operating procedures, ensuring reproducibility, comparing results with existing methods, and training other team members on the validated method.
Mid Level Questions
Q: What safety procedures do you follow when handling samples for CE analysis?
Expected Answer: Should describe proper handling of biological samples, use of personal protective equipment, and following laboratory safety protocols and documentation procedures.
Q: How do you maintain quality control in CE analysis?
Expected Answer: Should explain running control samples, maintaining calibration curves, documenting results, and following standard operating procedures.
Junior Level Questions
Q: What is the basic principle of Capillary Electrophoresis?
Expected Answer: Should be able to explain in simple terms how the technique separates molecules based on their size and charge, and describe basic sample preparation steps.
Q: How do you prepare samples for CE analysis?
Expected Answer: Should demonstrate knowledge of basic sample preparation techniques, including proper dilution, filtering, and storage of samples.
