The O.I. Analytical DPM-16 is a discrete purging multisampler unit. 

The OI Analytical Discrete Purging Multisampler (DPM-16) is a 16-station automatic purging multisampler designed for use with any OI Analytical purge-and-trap sample concentrator. The DPM-16 can be equipped with a variety of sparge vessels, including needle and frit spargers of either 5-mL or 25-mL capacity, and 18 mm O.D. 10-mL disposable test tubes. (An adapter kit is available for 12 mm glassware.) The DPM-16 is the recommended multisampler for analyzing solids, sludges, soils, and water samples containing large amounts of particulates. It is also suitable for clean water analysis.

• Standard 16-sample capacity with capability of linking two multisamplers for extended sampling positions.

• Standard 18-mm fittings are designed for use with either 5-mL or 25-mL frit and needle nondisposable spargers, or 10-mL disposable glassware direct from the factory.
