The Starna RM-0614 Scientific Dichromate UV Absorptivity Standard from Thermo Fisher Scientific is a high-purity dichromate solution designed for calibrating and verifying the performance of ultraviolet-visible (UV-Vis) spectrophotometers. This solution is certified against NIST-traceable standards, ensuring its accuracy and reliability for use in various applications.
The Starna RM-0614 Scientific Dichromate UV Absorptivity Standard is a clear, colorless solution with a concentration of 0.01000 g/L potassium dichromate and 0.1486 g/L sulfuric acid. The dichromate ion absorbs UV light at a wavelength of 352 nm with a molar absorptivity of 1.3-1.7 x 104 M-1 cm-1. This makes it an ideal standard for the calibration of UV-Vis spectrophotometers, as it provides a strong and well-defined absorption band.
This standard comes in a glass ampoule with a volume of 50 mL, sealed with a PTFE-lined septum. The ampoule is packaged in a protective outer carton to ensure safe transport and handling. The solution is stable under normal conditions, but it is recommended to avoid exposure to direct sunlight and to store it at room temperature.
The Starna RM-0614 Scientific Dichromate UV Absorptivity Standard is suitable for use in various industries, including pharmaceuticals, food and beverage, and environmental monitoring. It can be used to calibrate UV-Vis spectrophotometers for the analysis of various compounds, such as drugs, pigments, and dyes. The standard is also useful for verifying the accuracy and precision of UV-Vis measurement methods and for quality control applications.
In summary, the Starna RM-0614 Scientific Dichromate UV Absorptivity Standard is a high-purity, NIST-traceable solution for calibrating and verifying the performance of UV-Vis spectrophotometers. Its clear, colorless solution with a strong and well-defined absorption band at 352 nm makes it an ideal standard for various applications in various industries. The glass ampoule is packaged in a protective outer carton and is stable under normal conditions.
