An introduction to grab sampling
Representative process samples can help you gauge and maintain product quality. To obtain accurate process samples consistently, it’s important to understand why sampling processes matter, how system design affects sample representativeness, and established best practices for effective sampling.
Grab sampling also known as spot sampling, laboratory sampling, field sampling, or sometimes just sampling—involves the collection of a sample fluid in a pipeline, tank, or system. The sample is then analyzed to help operators validate process conditions, evaluate products for environmental emissions according to local regulations, and detect whether the product is up to customer specifications.
