PerkinElmer Spectrum 2000 FTIR

Our Spectrum 2000 FTIR allows spectroscopic investigations of the mid and near infra-red regions.

Samples can either be analysed using direct transmission (either as a raw material or in a KBr matrix) or via specular reflectance.

Applications:

  • Structural determination
  • Bonding relations
  • Sample composition

Specification:

Range - mid IR 4000 - 400cm-1 wave numbers (2.5 - 25μm)
Range - near IR 14000 - 4000cm-1 wave numbers (0.8 - 2.5μm)
Measuring modes
Transmission & specular reflectance
Resolution 0.5 cm-1
