Implementation and alignment of a Raman spectroscopy array for powder and liquid samples

This paper presents the methodology for the implementation of a conventional Raman spectroscopy array for the qualitative analysis of powder and liquid samples. An alignment methodology has been established for a Raman array with 180 ° geometry and sample collection on two axes. The array has been optimized to collect Raman signal in the 540 to 700 nm region (Δv: 160 cm-1 to 4000 cm-1) with integration times of up to 8 seconds without risk of Rayleigh band overlap.
