Product Overview
This UV-VIS samarium solution is a high-purity spectroscopy-grade standard designed for accurate wavelength calibration in UV-VIS spectrometers. The solution contains samarium ions dissolved in a stable matrix, providing sharp, well-defined absorbance peaks across the UV and visible spectrum. Its consistent performance ensures reliable calibration, minimizing instrumental drift and improving measurement accuracy. The formulation is optimized for long-term stability, reducing the need for frequent recalibration. This solution is compatible with most standard UV-VIS spectrophotometers, making it a versatile choice for laboratories requiring precise wavelength verification. The 100 ml packaging offers an optimal balance between sufficient volume for multiple calibrations and convenient storage. Each batch undergoes rigorous quality control to maintain uniformity and traceability, meeting the stringent requirements of analytical laboratories.
FAQs
1. What is the shelf life of this samarium solution when stored properly?
The solution maintains its calibration properties for at least 12 months from the date of manufacture when stored in its original container at room temperature, protected from light.
2. Is this solution compatible with both single-beam and double-beam spectrophotometers?
Yes, the samarium solution is formulated to work with all standard UV-VIS spectrophotometer configurations, including both single-beam and double-beam instruments.
3. What are the key absorbance peaks for this samarium standard?
The solution exhibits characteristic peaks at approximately 402 nm, 418 nm, 464 nm, and 480 nm, which are used for wavelength verification.
4. Can this solution be used for photometric accuracy verification?
While primarily designed for wavelength calibration, the consistent absorbance values can also serve as secondary reference points for photometric verification when used with proper controls.
5. What material is the container made of to ensure solution stability?
The solution is packaged in high-density polyethylene (HDPE) bottles with polypropylene caps, which provide excellent chemical resistance and light protection to maintain solution integrity.
