Holmium oxide is used as standard reference to check wavelengts.
Holmium oxide is used in calibration of UV spectrophotometers because it has well-defined absorption peaks at specific wavelengths in the UV range. These peaks can serve as reference points for calibrating the instrument and verifying its accuracy. Holmium oxide provides a reliable and stable reference for wavelength calibration in the UV spectrum.

Holmium is a member of the lanthanides group. As a curiosity holmium has the greatest magnetic strength between the elements. Applications: as holmium oxide for the calibration of spectrophotometers, neutron adsorbent, lasers, colorant for glass, etc.
Erbium has a strong absorption in uv and visible range, It is used in HPlc calibration for the wavelength accuracy verification of the PDA detector.
Potassium dichromate is used in UV calibration as a secondary standard to verify the accuracy of the instrument's wavelength calibration. Its absorption peak at 350 nm is well established, making it ideal for checking the alignment and accuracy of the UV spectrophotometer's wavelength scale. It provides a reference point that helps ensure the instrument is operating correctly for UV measurements.
Potassium chloride is used for calibration of the limit of stray light in UV because it produces a distinct absorption peak around 198 nm, which allows for accurate calibration of the spectrophotometer at this wavelength. This helps to ensure that any stray light present in the UV spectrum can be accurately quantified and minimized during measurements.
Kirchhoff's law of calibration (KCL) is used in the calibration of UV-Visible spectrophotometers to ensure accurate measurements of absorbance. It states that the absorbance of a sample is directly proportional to its concentration and path length. By applying KCL during calibration, you can establish a linear relationship between absorbance and concentration, allowing for precise determination of sample concentrations in subsequent measurements.
The solution of potassium chloride is used to evaluate the stray light.
Holmium is a rare earth chemical element. It has a very high magnetic strength and hence is used in the strongest of magnets. It also absorbs neutrons and hence is used in the control rods of nuclear power stations.
Toluene has clear absorption peaks at 266 nm and 269 nm. Hexane is only the solvent.
Holmium: The number of protons per nucleus of an atom is the same as its atomic number.
Holmium's abreviation is Ho
