Advion Touch ExpressTM Open Port Sampling Interface: direct analysis of solids, liquids, surfaces and fibers

The Touch Express Open Port Sampling Interface (OPSI), is designed for simple sampling of solids, liquids and sample preparation tips and fibers. Paired with the electrospray ion source of the expression Compact Mass Spectrometer, any soluble sample touching the port is analyzed by the mass spectrometer in seconds. The OPSI source is a unique, prep-free sample technique that offers:

  • Compound ID and impurity detection from almost any surface
  • Direct assays from sample preparation tips and SPME fibers
  • Easy screening applications for drug research, food safety, environmental, forensics
  • Large molecule applications including proteins, peptides, oligonucleotides and polymers
