High-End Research Applications Using VERTEX Series Vacuum Spectrometers

Bruker’s VERTEX 80v and VERTEX 70v vacuum FT-IR spectrometers provide highest flexibility and stability for advanced research applications. The entire vacuum optics design eliminates atmospheric disturbances in the resulting spectra and reduces artifacts caused by temperature fluctuations in the environment.

Description

Vacuum Advantages for FTIR Spectroscopy

No temperature fluctuation influenced by environment
No atmospheric absorbance masking weak spectral features or interfering with high spectral resolution features
No problems caused by fluctuations of the dry air purge supply
Highest stability and reproducibility
Utmost sensitivity
