HydraSleeve No-Purge Samplers

Pop and squeeze method shown with a HydraSleeve; a HydraSleeve being lowered into a well; and a sample being decanted from the HydraSleeve into a glass vial.

what is a HydraSleeve?

Unlike any other groundwater sampler, the HydraSleeve instantaneously "cores" a whole water sample from a defined vertical and horizontal interval (usually within the well screen). HydraSleeve samples do not blend fluid from different vertical zones or pull water in from outside the well screen, but instead sample via ambient and/or diffusive flow of groundwater through the well screen.

The sample is collected at in-situ pressure without purging and with very little down well disturbance, preventing turbidity, aeration or oxidation of sensitive parameters. Samples collected with the HydraSleeve correlate well to other sampling methods.

HydraSleeve samplers are inexpensive, disposable and very quick and easy to use, resulting in significant savings on capital equipment and operating costs when compared to other sampling equipment.

APPLICATIONS

HydraSleeve is suitable for both short and long term groundwater monitoring and is especially useful in narrow, constricted or damaged wells.

Cost savings of HydraSleeve sampling (typically 50 to 75%) make it the option of choice for monitoring UST leaks, dry cleaning plants and other small scale point-source contaminant sites. It can even be used for special challenges such as in-well vertical profiling of multi-layered contaminant concentrations.


EFFECTIVE

• Sample for ALL compounds

• Large sample volume

• Best sampler for slow recharge wells

• Conservative results comparable to conventional methods

• Repeatable sampling method

• Lower turbidity than purge and sample

• Slim cross section minimizes disturbance

• can be collected at in-situ pressure

• precise vertical and horizontal interval - no blending

• little or no aeration, agitation, degassing or displacement

• samples can be analyzed for all parameters

• samples a discrete, instantaneous "core" of water
