Hemoglobin (Hb) content is an important indicator for determining oxygen carrying capacity and anemia in clinical practice. Based on the content of hemoglobin, anemia patients can be screened. In addition, monitoring hemoglobin levels can understand the patient's blood loss situation and guide clinical transfusion management.

Continuous Emission Monitoring System (CEMS) is widely used in various boilers and kilns in industries such as thermal power generation, chemical, petrochemical, steel, waste incineration, coking, cement, etc. It is used for online monitoring of flue gas emissions from fixed pollution sources in industrial production processes and guiding the operation and control of flue gas desulfurization and denitrification systems.

Transmission/reflection spectroscopy is an important optical property of materials themselves. With the booming development of industry today, the quality control of material properties is becoming increasingly strict. Therefore, the use of fiber optic spectrometers for rapid and accurate measurement of transmission/reflection spectra is becoming increasingly mature. For different types of samples, in order to obtain better spectral data, the two basic modes of transmission and reflection will evolve into more forms.

Butterflies are renowned for their beauty and vibrant colors. Biologists are interested in measuring the reflectance of butterfly wings in the ultraviolet and visible ranges to better understand the species and its interconnections with ecosystems. The Avantes system can be effectively used to measure these fine biological samples. Avantes has recently conducted some tests on the samples provided by customers, and the results are impressive.

Most agricultural research is focused on studying how to supply the future massive increase in population. Year after year, farmers are trying to get more output from the same piece of land, but rapidly changing climate conditions have exacerbated soil depletion. How to effectively manage soil has become an urgent issue that people need to solve. Spectroscopy is one of the important technical means.

For over 120 years, agriculturalists have been aware of the importance of soil testing, especially elemental analysis, to ensure the health and productivity of crops. This is achieved by randomly sampling soil from representative areas of the field and sending them to the laboratory for analysis using chromatography, mass spectrometry, and various wet chemical techniques. Although precise, current methods are very time-consuming and costly.
