Spectroscopy Standards: Apollo Scientific
In spectrophotometry, a standard refers to a reference substance with a known and well-defined concentration, used to calibrate or verify the accuracy of a spectrophotometer. Spectrophotometric standards are essential to ensure accurate and reproducible measurements of the absorbance or transmittance of unknown samples.
The main types of spectrometry include:
- Mass spectrometry: Allows the determination of the composition and molecular structure of compounds by measuring the mass and charge of ions.
- Nuclear magnetic resonance (NMR) spectroscopy: Utilises the behaviour of atomic nuclei in a magnetic field to study the molecular structure and composition of samples.
- Infrared (IR) spectroscopy: Analyses the interaction of molecules with infrared radiation to identify functional groups and chemical structures.
- UV-visible spectroscopy: Measures the absorption of ultraviolet and visible light by molecules to determine the concentration of a sample and study electronic transitions.
Apollo Scientific offers a wide range of specialised consumables for various spectroscopic techniques. For infrared (IR) spectroscopy, it provides both polished and unpolished optics in a variety of materials, along with cells designed for the analysis of liquids, solids, and gases, as well as evacuable matrices for solid sampling. These products are designed to ensure accurate and reproducible measurements in chemical research and industrial analysis.
Additionally, Apollo Scientific supplies high-purity standards for mass spectrometry, ensuring reliable results at competitive prices. For nuclear magnetic resonance (NMR) spectroscopy needs, they offer a complete selection of deuterated solvents, tubes, and quality accessories. Complementing their offer, their line of ultraviolet (UV) spectroscopy products covers a wide variety of optical path lengths and shapes, made with the highest quality glass and quartz, ensuring precise and consistent results in UV analysis.
