Fritless Sparger: Compared to a frit sparger, the fritless sparger may be the better choice when a water sample has a tendency to foam. This sparger is not appropriate for soil samples, which tend to clog the capillary tube. Available in 1/2 and 3/4 in. mount sizes.
Disposable (Needle) Tubes: The most practical choice for soil (and other solid or semi-solid) samples, these tubes permit easy sample loading and inexpensive disposal. Available only in 3/4 in. mount size, a 3/4 in. tube can be used on the 7695A Purge and Trap concentrator with the adapter (to convert from 7695A Purge and Trap 1/2 in. to this 3/4 in. size).
Needle Sparger with Foam Trap: This sparger is designed for samples that foam, particularly if the foaming cannot be controlled by a fritless sparger. Available only in 1/2 in. mount size.
Frit Sparger: This is the most efficient design in terms of purging and it is the standard choice for clean drinking water. Available in 1/2 and 3/4 in. mount sizes.
The 7695A Purge and Trap concentrator has a 1/2 in. mount, and the automatic sampler has a 3/4 in. mount. An adapter is available to mount 3/4 in. glassware on the 7695A Purge and Trap concentrator, but there is no adapter for using 1/2 in. glass on the automatic sampler.
