Top 10 Questions for Wet Chemistry Analyst Interview

1. What are the different types of wet chemistry techniques used in analytical chemistry, and which one do you have experience with?

There are various wet chemistry techniques used in analytical chemistry, each with its own advantages and applications. Some of the most common techniques include:

• Titration: A technique that involves adding a known amount of a reagent to a solution until a chemical reaction is complete. It is used to determine the concentration of a substance in a solution.
• Gravimetry: A technique that involves separating and weighing a solid precipitate to determine the amount of a substance in a solution.
• Colorimetry: A technique that involves measuring the absorbance of light by a solution to determine the concentration of a substance in a solution.
• Electrochemistry: A technique that involves measuring the electrical properties of a solution to determine the concentration of a substance in a solution.

I have experience with all of these techniques, but I am most proficient in titration and gravimetry. I have used these techniques to analyze a variety of samples, including water, soil, and food.

2. What are the key steps involved in performing a wet chemistry analysis?

Planning

• Identify the analyte(s) of interest and their expected concentration range.
• Select an appropriate wet chemistry method based on the analyte(s) and expected concentration range.
• Gather the necessary equipment, reagents, and standards.

Sample Preparation

• Weigh or measure a representative sample of the material to be analyzed.
• Dissolve or extract the analyte(s) from the sample using an appropriate solvent or reagent.
• Dilute or concentrate the sample to bring the analyte(s) concentration within the range of the selected method.

Analysis

• Perform the wet chemistry analysis according to the selected method.
• Record the results of the analysis, including any observations, measurements, and calculations.

Data Interpretation

• Calculate the concentration of the analyte(s) in the original sample.
• Interpret the results in light of the expected concentration range and any relevant quality control data.
• Generate a report or certificate that summarizes the results of the analysis.

3. What are some of the potential sources of error in wet chemistry analysis?

• Sampling error: This can occur if the sample is not representative of the material to be analyzed.
• Reagent error: This can occur if the reagents used in the analysis are not of high quality or have not been properly standardized.
• Equipment error: This can occur if the equipment used in the analysis is not properly calibrated or maintained.
• Operator error: This can occur if the analyst does not follow the correct procedure or makes a mistake in recording the results.

It is important to be aware of these potential sources of error and to take steps to minimize their impact on the results of the analysis.
