Product

• The introduction of the atmospheric-pressure photo-ionization (APPI) method enables the highly sensitive analysis of low-polarity compounds.
• Highly sensitive analysis of Deoxynivalenol, a Fusarium Mycotoxin, which is required for grain food safety, is possible.

Interface Lineup Extends the Application Range

The interface is easily replaced. Use ESI for high-polarity samples, APCI for medium-polarity samples, or APPI for low-polarity samples.

Features of APPI Interface

Allows high sensitivity analysis of compounds that have low polarity

Allows highly sensitive analysis of low-polarity compounds, which cannot be adequately addressed using conventional LCMS ionization methods.

Allows high sensitivity analysis of Fusarium toxins

Draft standards restrict the amount of deoxynivalenol contained in wheat flour to 1.1 ppm, which is the toxin in Fusarium mold, but APPI allows analyzing these toxins at concentrations far lower than required by the draft standard.

Allows not only APPI, but also a simultaneous APCI/APPI dual ionization mode

The APPI Kit is attached via the LCMS-2010EV interface section and is used in conjunction with the existing APCI probe. Switching to ESI and APCI modes is easy.

The Principal of APPI

Atmospheric pressure photo ionization (APPI) is a new ionization method that ionizes samples with UV light. It achieves highly sensitive analysis of low-polarity compounds. The mobile phase and sample supplied by the pump are vaporized in the APCI probe by the nebulizer gas and heater and subsequently ionized by UV light.
