APPI II
Atmospheric pressure photo ionization (APPI) is used for less polar or non-polar molecules that can not be ionized in either ESI or APCI.
APPI delivers a wide dynamic range and low chemical noise. With an operational flow range of 2µl/min – 1500µL/min it is compatible with cap- to analytical chromatography.
APPI II by Bruker Daltonics is the only APPI source with DirectProbe option for direct analysis of solid samples. The direct injection probe is a novel smart solid sample introduction technique allowing a rapid analysis of solids.
The DirectProbe (DIP) add-on for the Bruker APCI II and APPI II ion sources allows direct analysis of liquid and solid samples without tedious sample preparation. In routine organic synthesis analyses, it simplifies identification and characterization of chemical reaction products without compromising sensitivity.
Fields of applications:
General Chemistry (synthesis control)
Manual quality control of solids (Pharma, oil, explosives)
Customs (drugs of abuse, explosives)
Homeland security
Environmental
Thermal degradation processes (plastic production)
Classical routine analysis (e.g. confirmation of sum formula)
