Carryover is a common problem in environmental labs. Many advances over the years have been developed to tackle this issue. These innovations vary from increasing bake times and bake flows to changing the flow path tubing to more inert materials. However, all these improvements do nothing to reduce the most common source of carryover: the sparge vessel. This application will evaluate a patented innovation for cleaning the sparge vessel during an analytical sequence.
