Sample interview questions: What analytical techniques do you commonly use to monitor and analyze chemical processes?
Sample answer:
-
Gas Chromatography (GC): GC is used to separate and analyze volatile organic compounds (VOCs) and other gases. It is a widely used technique for monitoring air quality, detecting leaks, and analyzing the composition of chemical reactions.
-
High-Performance Liquid Chromatography (HPLC): HPLC is used to separate and analyze non-volatile compounds, such as pharmaceuticals, pesticides, and proteins. It is a versatile technique that can be used for a wide range of applications, including quality control, drug discovery, and environmental monitoring.
-
Mass Spectrometry (MS): MS is used to identify and quantify compounds based on their mass-to-charge ratio. It is a powerful tool for analyzing the structure and composition of molecules. MS is often used in conjunction with GC or HPLC to provide a comprehensive analysis of a sample.
-
Nuclear Magnetic Resonance (NMR): NMR is used to study the structure and dynamics of molecules. It is a non-destructive technique that can be used to analyze solids, liquids, and gases. NMR is commonly used in drug discovery, materials science, and chemical engineering.
