Sample Preparation
Sample Preparation is a fundamental laboratory process where materials are made ready for testing and analysis. It's like getting ingredients ready before cooking - the samples need to be in the right form and condition before they can be tested. This might involve cutting, dissolving, filtering, or treating materials so they can be examined properly. Good sample preparation is essential because it affects how accurate the test results will be. This skill is needed in many fields, from medical laboratories to environmental testing to food safety.
