What truly challenging problems can a 2 nm bandwidth Visible Spectrophotometer solve?
A: 2 nm bandwidth Visible Spectrophotometer is like an "optical microscope" for high-precision experiments.
2. Precise measurement of extremely high-concentration samples.
Why do industries like pharmaceuticals and fine chemicals typically require equipment with a 2 nm bandwidth?
A: Global Pharmacopoeia (USP, EP) compliance explicitly stipulates that the hardware specification for identifying, checking for impurities, and determining the content of specific drugs must have a spectral bandwidth of no more than 2 nm.
Furthermore, in international quality audits, 2 nm is a significant advantage for obtaining advanced ISO/IEC 17025 laboratory accreditation.
