Mass spectrometer ion source DPiMS™ QT

Overview
The DPiMS™ QT probe electrospray ionization kit attaches to quadrupole time-of-flight (Q-TOF) mass spectrometers to enable direct electrospray ionization from a probe. It permits selection and introduction of extremely small sample volumes for rapid MS analysis and simplifies switching to ESI workflows in laboratory and clinical environments.

Product type
Probe electrospray ionization kit for mass spectrometers (direct ESI interface).

Features

• Simple pretreatment: analysis can start with minimal sample preparation, reducing turnaround time in routine workflows.
• Rapid analysis: compatible with quadrupole TOF systems to support high-resolution mass measurements.
• Low sample carryover and stability: only a small portion of sample adheres to the probe, lowering contamination risk to the MS inlet.
• Software integration: probe operation and acquisition can be controlled via PESI MS Solution by selecting probe control mode and MS method.

3 Step Workflow
Illustrated three-step procedure for sample introduction and acquisition: load sample on probe, engage probe ESI mode, acquire spectra.
