QDUKI Welcomes Molecular Vista Nano-IR Microscopes

Quantum Design UK and Ireland is excited to add Molecular Vista to its product portfolio. Offering the highest resolution nanoscale chemical analysis instruments available, the range of Nano-IR microscopes features photo‑induced force microscopy (PiFM) and photo‑induced force IR spectroscopy (PiF‑IR).

Perform Chemical Analysis on Smaller Volumes than Ever Before

PiFM allows fast and automated nano‑scale material analysis with minimal setup between samples.

Better than both FTIR and NANO-FTIR.

PiF‑IR spectra provide FTIR-like results at the nano scale in milliseconds with even greater resolution and SNR than nano-FTIR. Other nano-IR techniques have yet to show separate images of distinct chemical components imaged at the associated IR bands on such tightly packed BCP.

What is PiFM?

Think of PiFM as supercharged nano-FTIR imaging with ~5 nm spatial resolution and superfast nanoscale IR spectroscopy (as fast as 0.1 second for full spectrum.) PiFM acquires both topography and chemical signature at the nanometer scale and demonstrates excellent sensitivity (monolayer), good correlation to bulk FTIR spectra, and universal applicability to a wide range of organic and inorganic materials.

Application

PiFM chemical mapping provides unbeatable lateral IR resolution for analysing surface chemistry.

An elementary cellulose fibril is embedded in the lignin matrix of a cell wall from spruce wood. Scan dimensions: 150 nm × 150 nm × 10.5 nm.

Advantages

  • Exceptional Spatial Resolution in Chemical Mapping
  • Excellent Sensitivity
  • Good Correlation between PiFM and Conventional IR Spectra
  • Universal Sample Applicability
  • Hyper-spectral Nano-IR Imaging
  • Exceptional ease of use
