What is the main goal of sample storage procedures?

The main goal of sample storage procedures is to maintain the integrity of the sample until analysis. This process is crucial because the quality and reliability of analytical results depend significantly on how samples are stored. Proper storage protects samples from degradation, contamination, and any changes that could occur due to environmental conditions, such as temperature fluctuations, exposure to light, or humidity. By maintaining the sample in its original state, analysts can ensure that the results of the testing accurately reflect the conditions present at the time of collection, which is vital for compliance with environmental regulations and for making informed decisions based on the data derived from the samples.

While allowing easy access to samples, tracking sample history, and facilitating faster analysis are important aspects of sample management, they are secondary to the primary goal of protecting the sample's integrity. If the sample's integrity is compromised due to improper storage, any subsequent analysis may yield misleading results, negating the benefits of easy access, historical tracking, or quicker analysis. Hence, maintaining the integrity of samples is paramount in environmental compliance settings.
