I'm interested in sourcing a spectrometer with specific features. The device should have a wavenumber range of 600 to 6000 cm-1, with a resolution of 1 cm-1 and an accuracy of ±0.05 cm-1. Additionally, it should include a ZnSe beam splitter with automatic changeover capabilities for MIR to NIR and FIR, and a gold-coated mirror. The detector must be a Deuterated L-Alanine doped Triglycine Sulphate with temperature control, paired with a high-intensity ceramic light source. The unit should be capable of analyzing liquid, solid, and powder samples and come with an included ZnSe ATR crystal. Lastly, analysis should be viewable through a PC interface, and the system should achieve a peak-to-peak signal-to-noise ratio of at least 30,000:1.
