Low-Background (dead) Water

This freshwater is collected from an artesian well that is screened at a depth of >100 m below the water table. Based upon hydraulic conductivity this water has not been in contact with the atmosphere for several thousand years and should therefore contain undetectable amounts of tritium. Analysis of this water by the University of Miami Tritium Laboratory indicates that the tritium levels are below their detection limit (<0.1 TU). This water is suitable for use as analytical instrument, field and equipment blanks. The water will be delivered in 1 liter polythene bottles. A copy of the batch analysis will be provided.

Product Code: BGW-1LB
