Direct Probe Ionization Mass Spectrometer

The DPiMS-2020 is a single quadrupole mass spectrometer based on using probe electrospray ionization. It uses a probe to remove a micro quantity of liquid from the sample placed on the sample plate and inject it into the MS unit for mass analysis.
It is extremely easy to operate and it is able to measure samples such as chemical products, food materials, and biological samples, directly or with very minimal sample pretreatment.

Quick and Easy Measurement Without Sample Preparation

Measure Samples Directly, Quickly, and Easily with PESI Unit

Features of PESI (Probe Electrospray Ionization)

  • Perform MS analysis directly on the sample.
  • Suitable for thermally labile compounds, no direct heat applied.
  • Highly resistant to MS contamination, even with complex matrices.
