INTRODUCTION
Water composite
sampling is a technique used in environmental monitoring to obtain
representative samples of water from a specific location over a period
of time. Instead of collecting individual samples at frequent intervals,
composite sampling involves combining multiple smaller samples taken at
regular intervals to create a single, averaged sample that represents
the water quality over the entire sampling duration. This method helps
to reduce variability and provides a more accurate representation of the
water's quality.
Here's how the process generally works :
Here's how the process generally works :
- Sampling Strategy: Determine the goals of your monitoring and the frequency of sampling. For example, you might want to monitor a water quality over a day, a week, or a month. Decide how many individual samples you'll collect during this period.
- Sampling Frequency: Based on your chosen duration, divide it into intervals for collecting individual samples. For example, if you're monitoring over a day, you might collect samples every hour.
- Sample Collection: At the designated intervals, collect a small water sample from the monitoring location. It's important to use consistent methods and equipment for collecting each sample to maintain accuracy.
- Sample Preservation: Depending on the parameters you're testing (such as temperature, pH, dissolved oxygen, pollutants, etc.), you might need to preserve the collected samples to prevent changes in their properties before they are combined.
- Composite Creation: After the sampling period is complete, combine the individual samples in equal proportions (by volume or weight) to create a composite sample. For example, if you collected 24 hourly samples over a day, each individual sample would contribute 1/24th to the composite.
- Analysis: Perform laboratory analysis on the composite sample to determine the average water quality over the monitoring period. This can include various chemical, physical, and biological tests to assess the overall water condition.
OUR AUTOMATIC COMPOSITE SAMPLER WILL COLLECT THE
WATER SAMPLE ON FREQUENT INTERVALS AND STORE IT IN A CABINET AT 4 DEG C
