We house a Perkin–Elmer Lambda 19DM UV/Vis spectrometer using UV WinLab software.
The instrument is a double‐beam, double‐monochromator, ratio‐recording spectrometer operating in the ultraviolet and visible spectral ranges (total usable wavelength range: 175–900 nm).
The sample cells can be thermostated between 15 and 35 °C and the sample chamber can be purged with an inert gas.
