What sampling method is used for HPC analysis?

For HPC (Heterotrophic Plate Count) analysis, the correct sampling method involves using sterile plastic or glass containers. This is essential because sterile materials prevent contamination of the sample, ensuring that the bacterial counts are accurate and reflective of the water quality. The integrity of the sample is crucial in HPC analysis, as the goal is to determine the number of viable bacteria present in the water, which can be influenced by any introduced contaminants.

When using sterile plastic or glass containers, they help maintain a controlled environment for the sample during transport and processing. This is important to avoid any potential growth of organisms that could occur if the sample were to come into contact with non-sterile materials. Overall, the use of sterile containers aligns with best practices in microbiological methods, ensuring reliable results for HPC analysis.
