RM-06HLKI UV-VIS Reference Set NIST traceable

The NIST traceable reference set, RM-06HLKI, can help you to test the three most important parameters of your spectrophotometer. These are absorbance scale, wavelength scale and stray light. The reference set is very easy to use. There is no chemical preparation. Each reference is a far UV quartz cell which has had the reference materials permanently heat sealed into the cells. Certificate of Calibration and Traceability Each set comes with a NIST traceable certificate of analysis. Our certification laboratory is inspected and accredited by UKAS under ISO/IEC 17025 and ISO Guide 34. Potassium Dichromate - Used for: Verification of the UV absorbance scale Useable range: 235nm to 350nm. The potassium dichromate reference is supplied as two cells, a blank and a 60mg/L cell. The 60mg/L cell is read against the blank at four wavelengths: 235, 257, 313, and 350nm. The certificate provided will give the expected absorbance values at those wavelengths. Holmium Perchlorate - Used for: Verification of the wavelength scale Useable range: 240nm to 650nm. Holmium perchlorate has 14 defined (by NIST) absorbance peaks. You can relate the wavelengths at which your instrument finds these peaks to the wavelength scale of your instrument. Periodic use will assure that your wavelength scale is correct. Holmium has sharply defined peaks across both the UV and the visible spectra. Potassium Iodide - Used for: Stray Light assessment. Useable range: 190 nm to 280nm Stray light is an indication of transmitted light by your instrument when no light is being transmitted through the sample. Stray light can create problems with both sensitivity and accuracy if it exceeds the specification for your instrument. Potassium Iodide will allow you to easily test and assure that stray light is not out of specification.
