The company has recently extended the scope of their ISO/IEC 17025 accreditation to include a number of new Certified Reference Materials (CRM) for UV and visible spectrophotometry. These include sealed-in-cell liquid wavelength and absorbance standards for use at wavelengths down to 200 nm, and a new sodium nitrate "cut-off" solution for estimating stray light at 340 nm.
