PerkinElmer Frontier FTIR

Our Frontier FTIR allows spectroscopic investigations of the mid infra-red regions.

Samples can 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 7000 to 400cm-1 wave numbers (1.4 to 25μm)
Measuring modes
Transmission & specular reflectance
Resolution 0.5 cm-1

PerkinElmer Lambda 900 UV/Vis/NIR spectrometer

Our Lambda 900 Spectrophotometer allows spectroscopic investigation of the UV, visible and near-IR regions of your sample material. Sample holders are available to accept either solid films or plates, or cuvettes for liquid samples.

Applications:

  • Quantitative determination of analytes
