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 can accept either solid films or plates, or cuvettes for liquid samples.
Applications:
- Quantitative determination of analytes
Specification:
| Wavelength range | 185 to 3300nm |
| UV/Vis resolution | < 0.05nm |
| NIR resolution | <0.20nm |
| Accuracy |
+/- 0.08nm UV/Vis +/- 0.30nm NIR |
| Reproducibility |
UV/Vis <0.020nm NIR <0.080nm |
