Which of the following is a sample type mentioned in sample acceptance?

• A. Drinking Water
• B. Glassware
• C. Calibration Solution
• D. Filter Paper

Answer: (A)

Sample acceptance focuses on materials that will be analyzed, ensuring their integrity from collection through testing. Drinking water fits this because it represents a typical matrix that labs routinely analyze for quality and regulatory compliance, with well-defined requirements for how the sample must be collected, preserved, labeled, and transported so that the results reflect the true water quality. Glassware, calibration solution, and filter paper aren’t samples to be tested; they are equipment, standards, or consumables used during analysis and have their own readiness criteria (cleanliness, calibration status, integrity). So drinking water is the sample type mentioned in sample acceptance.
