Overview

Specifications

  • Spectral selection by common chemical name or CAS number
  • Spectral resolution 0.112 cm-1 at full width, half maximum height (FWHM)
  • Includes chemical formula, molecular weight (grams/mole), freezing and boiling point (oC) and vapor pressure (mm Hg at 25 oC)
  • Display full spectrum (typically 600 to 6,500 cm-1) or user selected range using cursor (single-tap and double-tap) or entering values by keyboard
  • Switch between Wavenumbers and Wavelength (microns)
  • Instantly see integrated cross-section of displayed spectrum (cm*molecule-1)
  • De-resolve spectra by convolving with Gaussian filter (0.5 to 15 cm-1 FWHM)
  • Change concentration (parts per million) and path length (meter)
  • Display spectra in absorbance or transmittance
  • Display absorbance in base-10 or base-e
  • Display and save spectra as low-to-high or high-to-low wavenumber/microns
  • Save entire or selected portion of spectrum, as plain text file
