Agilent chemical standards and accessory kits provide an inexpensive and time-saving solution for OQ/PV. The kits are designed for analysts who need to conform closely to both quality and regulatory requirements when performing UV-visible measurements.
 
Solutions include holmium oxide for wavelength accuracy measurement; potassium dichromate for photometric accuracy measurement; sodium nitrite, sodium iodide and potassium chloride for stray light measurements at 340, 220 and 200 nm; and toluene in hexane for resolution measurement.
