A mass spectrometer is a laboratory instrument used to separate ions in a sample with a different mass/charge ratio (m/z). The mixture may consist of different isotopes of the same substance or different chemical elements.

Measurements from this equipment can generally be used to calculate the exact molecular weight of the sample components as well. In other words, mass spectrometers can be used to identify unknown compounds by determining the molecular weight, quantifying known compounds, and determining the structure and chemical properties of molecules. This is done thanks to its structure that usually includes at least these three components: ionization source, mass analyser and ion detection system.

The multi-angle spectrophotometer adopts an industrial quality MCU and equipped with 3 measuring angles, under the superior performance of the optical measuring system compatible with the multi-angle spectrophotometer  it has excellent performance in measuring multi-angle chromatic aberration, even on the curved surface, but also has high precision and measurement stability. The Kalstein multiangle spectrophotometer  is used to measure the difference in color of surface paint affected by different viewing angles and viewing conditions.

It can provide accurate and consistent color measurement for metallic, pearl and other finished products with complex special effects.

There are several types of spectrophotometers. These will be classified according to the type of sample analyzed; there is atomic absorption and molecular absorption (UV-VIS spectrophotometer). A UV-VIS spectrophotometer is based on the absorption process of visible ultraviolet radiation (radiation with a wavelength of 200 to 780 nm) by one molecule. The absorption of this radiation causes the promotion of an electron to an excited state. The electrons that are excited by an absorbent radiation of this frequency are the binding electrons of the molecules, so the absorption peaks can correlate with the different types of bonds present in the compound. Therefore, UV-VIS spectroscopy is used to identify the functional groups present in a molecule. Bands appearing in a UV-VIS spectrum are large due to the superposition of vibrational and electronic transitions.
