Hi Fellows, could someone please point me towards the source of a known high purity imidazole with low absorbance at 280 nm? I am facing the problem of detecting a low absorption protein in high imidazole background after IMAC gradient elution. In the UV spectra of the 2 imidazoles I checked there is some contaminant that absorbs at 280...
