Integrated Stream Switching (ISS™)
Our favorite way of sample prep is becoming more and more popular! Spark pioneered online sample prep (solid phase extraction, column switching) and introduced online sample prep as an integrated option on an autosampler over 20 years ago. Today, online sample prep using high pressure stream switching is considered the best approach to obtain high assay quality and maximum automation. In addition, online sample prep using valve switching provides a closed sample processing system – another plus for sample integrity.
