WebCross-sectionally integrated, flow-weighted (flow-integrated) sampling is used to collect a composite water sample in a stream cross-section such that the dissolved and suspended material in the sample is in proportion … WebWith the water sample size control, you can take individual time-weighted composite samples or full-bottle discrete grab samples in a 2.5 gallon sample bottle. The water sample interval control allows you set the time between individual composite samples or enable the external trigger mode for flow proportional sampling.
Web2. Wastewater samples will typically be collected either by directly filling the sample container or by using an automatic sampler or other device. 3. During sample collection, if transferring the sample from a collection device, make sure that the device does not come in contact with the sample containers. 4.
