• Rapid sample introduction by flow injection with or without an LC column.
The APCI technique can be used for volatile and thermally labile compounds with minimal
thermal decomposition. The rapid desolvation and vaporization of the droplets and entrained
analyte minimizes thermal decomposition and preserves molecular identity for ionization by the
corona discharge needle. Buffers are readily tolerated by the ion source without significant
contamination and the flash vaporization of the sprayed effluent allows up to 100% water to be
used. The probe can accept the entire effluent, without splitting, at flow rates from 200 µL/min to
3,000 µL/min, through a wide-bore column.
