Product Overview
This UV-VIS holmium oxide solution serves as a precision wavelength standard for UV-VIS spectroscopy applications, offering consistent and reproducible absorption peaks across the 240-650 nm range. The solution is prepared from high-purity holmium oxide dissolved in perchloric acid, ensuring long-term stability and minimal batch-to-batch variation. Each set contains a sealed ampoule with pre-determined concentration, eliminating the need for dilution or preparation. The standard’s sharp absorption bands at 241.15 nm, 251.13 nm, 287.15 nm, 361.37 nm, 418.47 nm, 451.13 nm, 485.40 nm, 536.45 nm, and 637.48 nm provide reliable reference points for instrument calibration and performance verification. The solution is packaged in a light-resistant container to prevent photodegradation, with a shelf life of 24 months when stored at room temperature. Its compatibility with most UV-VIS spectrometers makes it an essential tool for maintaining instrument accuracy in analytical laboratories.
FAQs
1. What is the concentration of holmium oxide in this standard solution?
The solution comes pre-formulated at an optimized concentration that produces distinct absorption peaks without requiring further dilution. Exact concentration values are provided in the certificate of analysis included with each set.
2. Can this standard be used with both single-beam and double-beam spectrometers?
Yes, the holmium oxide solution is compatible with all UV-VIS spectrometer configurations, including single-beam, double-beam, and diode-array systems. The stable absorption profile ensures consistent results across different instrument types.
3. How often should this standard be replaced for routine calibration?
Under proper storage conditions (room temperature, protected from light), the solution remains stable for up to 24 months. For laboratories performing daily calibrations, we recommend replacing the standard annually to account for potential minor degradation over time.
4. What wavelength range does this standard cover effectively?
The holmium oxide solution provides well-defined absorption peaks between 240 nm and 650 nm, covering the entire UV and visible spectrum range of most analytical applications. The most prominent peaks occur at 241 nm, 287 nm, 361 nm, 418 nm, and 536 nm.
5. Is this standard traceable to any international reference materials?
Each batch is manufactured following ISO 17034 guidelines and comes with a certificate of analysis that includes traceability information to NIST reference materials where applicable, ensuring metrological reliability for your calibration procedures.
