Learn about a recent presentation on grab sampling best practices by Swagelok's Mike Strobel, BSc., IE, Field Engineer/Americas.
Grab sampling is the science of safely capturing a sample from a process, pipeline, or tank while maintaining the chemical composition during storage or transport for later analysis. Worker safety and ensuring samples are representative and timely are grab sampling's main goals. Other common names for grab sampling are "laboratory sampling", "field sampling", and "spot sampling".
Grab sampling is particularly important for:
There are three key design considerations, having to do with continuous flow, "flush" time, and purge fluid. With respect to cylinder sampling, specifically, Strobel says best practices call for operators to:
With respect to bottle sampling, best practices call for operators to:

Swagelok grab sampling systems satisfy gas and liquid non-slurry sampling service in a consistent, reliable package. Two system types allow for capture into one of two types of containers: pressure‑containing metal cylinders as found in the Grab Sample Module (GSM) or non-pressure‑containing glass or polyethylene bottles as found in the Liquid Only Sampling Module (GSL).
