Once the samples have been collected, they are then subjected to various analytical techniques such as chromatography, spectroscopy, or mass spectrometry. These tests allow us to identify the presence of certain chemicals within the sample, which can be used to make an identification.

Once the results of the tests have been obtained, it is important to compare them to known reference standards. This allows us to determine if the substances found in the sample match those of a known substance. If there is a match, we can confidently make an identification. Finally, all data must be documented thoroughly so that it can be presented in court if necessary. By following these steps, I am confident that I can accurately make an identification based on the chemical analysis of evidence.”

22. Tell us about a difficult case where you had to use your forensic chemistry skills.

This question can help the interviewer understand how you use your skills to solve problems and make decisions. Use examples from your experience that show how you used critical thinking, problem-solving or analytical skills to find a solution.
