Overview

The wavelength calibration standard substance for the Starna HPLC detector in the UK is used for wavelength calibration of HPLC diode array detectors that can be placed in a 10mm optical path colorimetric cell at the sample detection position; A 10% v/v perchloric acid solution of erbium oxide (1% m/v) is sealed in a 10mm optical path far ultraviolet quartz colorimetric cell that is fused together. All Starna reference materials are traceable to NIST and have calibration certificates accredited by UKAS ISO/IEC 17025 and ISO Guide 34

Calibrate with a perchloric acid solution of erbium oxideHPLCThe wavelength of a diode array detector is a method specified in many documents. High chloric acid solution of erbium oxide at wavelength230nm—260nmWithin the spectral range, there are9A distinct characteristic peak.

9The wavelength of each peak is approximately:255, 364, 379, 405, 449, 487, 522, 541, 652.

Explanation: The above certified wavelength values are for reference only, and the actual values are determined by the spectral bandwidth. The certification certificate provided with the product specifies1.00and5.00 nmAuthentication wavelength under bandwidth, if required by the customer,StarnaCan provide authentication values for other bandwidths and wavelengths.
