Flow Through Desorption (FTD™)

Innovative patented Flow-through desorption (FTD™)* technology provides direct elution of DBS from cards into your mass spec and other analytical systems without punching discs. Optional on-line clean-up and analyte separation prior to analysis by mass spec or other analytical systems, provide maximum sensitivity without any manual intervention. With the potential for many other biological samples, the DBS Autosampler™ from Spark Holland sets a new standard for analysis!
