Standards for spectrophotometry

Bandwidth standard. Control of the ratio between the peak value at 268.7 nm and the trough value at 266.8 nm. Complies with the European Pharmacopoeia.

Absorbance/transmission and linearity standard in UV (235, 257, 313 and 350 nm). Control of absorbance measurement for different wavelengths in the UV (response linearity). Complies with the European Pharmacopoeia.

Resolution standard for derived spectrophotometry. Complies with the European Pharmacopoeia.

Baseline stallion. Stray light control. Complies with the European Pharmacopoeia.

Wavelength standard from 240 to 640 nm (certified for bandwidths of 0.1 nm, 0.2 nm, 0.5 nm, 1 nm and 2 nm). Controls the absence of wavelength shift. Complies with the European Pharmacopoeia.
