What should be done to sampling devices before use in product samples?

Rinsing sampling devices before use is essential to ensure the accuracy and integrity of the product samples. This step helps to remove any contaminants or residues that may be present on the devices from previous uses or from their storage environment. By rinsing, you minimize the risk of cross-contamination, which can lead to incorrect sampling results and affect the quality assessment of the product being tested.

Preparing sampling devices properly contributes to reliable data collection, which is crucial for compliance with industry standards and regulations. It ensures that the samples reflect the true characteristics of the product, allowing for better decision-making based on accurate analysis. While other methods, like simply wiping or boiling, may not effectively eliminate all residues or contaminants, rinsing specifically addresses this need for cleanliness and reliability.
