NSG Precision Cells, a manufacturer of quartz-based flow channel cuvettes, flowcells and microchips has announced the availability of the WAV-7 Didymium Glass Calibration Standard, following the release of the Holmium Oxide Calibration Standard.
WAV-7 Didymium Glass Wavelength Calibration Filter
The Didymium Glass Calibration Standard is a stand-alone product that supports wavelength calibration of spectrophotometers in the visible and ultraviolet range. Furthermore, in the ultraviolet range it provides photometric accuracy at five wavelengths’ points. The WAV-7 Wavelength Calibration Standard is a highly durable solution that does not require any re-calibration or replacement. The calibration standard has received the Calibration Certificated from the NRC Institute for National Measurement Standard.
A high performance spectrophotometer is crucial and an incorrect wavelength calibration will result in inaccurate analysis while negatively affecting the finances of the company. A spectrophotometer that provides a high degree of wavelength scale accuracy is vital for gathering absorbance readings of a sample. Even a 1 nm deviation can result in incorrect data. Therefore, wavelength calibration testing is necessary for spectrophotometers to ensure accurate analysis. Since the testing process mandated by several agencies is expensive, the didymium glass calibration solution by NSG Precision offers an alternative solution to companies.
The advantages of WAV-7 didymium filter include optimal performance, high stability ensured by the nano-deposition proprietary manufacturing process, and elimination of recalibration issues. The easy-to-use, WAV-7 didymium filter calibration kit is provided with usage instructions. NSG Precision also provides a Certificate of Calibration for the product.
The NIST-compliant absorbance values provided by NSG Precision for photometric accuracy include 340, 320, 300, 280 and 270 nm.
