What is close to infrared spectroscopy?
Near infrared spectroscopy (NIR) is a type of spectroscopy in which a nearby infrared area of electromagnetic spectrum is used as an evaluation tool. This technology is used in many different industries, including pharmaceutical, food and agricultural industries, in certain medical diagnostic tests and in combustion and polymer science. Near infrared spectroscopy, it is particularly useful in diagnostic medicine because it is able to record changes in the condition of hemoglobin, a molecule transmitting oxygen in the blood. All types of mass absorb and emit light and study of the type of light that are absorbed or emitted, traces can be obtained in terms of the properties of the matters. The object absorbs or emits the light of certain colors or wavelengths depending on its temperature, weight, composition and other factors. Near infrared light refers to wavelength light between 800 and 2,500 nanometers (0.00003 to 0.00025 inches). This technology usesLight source to discourage light from the sample. The light, which is emitted by the sample, is then modified by the prisms of the disaping light, which divided the light into its component wavelengths. The scattered wavelength light between 800 and 2,500 is detected, recorded and evaluated to obtain the knowledge of the sample.
In the vicinity of infrared spectroscopy, it has several advantages over other types of spectroscopy, making it a technology that is used preferably in many situations. For example, NIR technology has a good signal ratio, which means that background values are generally low compared to the results of the test sample. This makes it easier for technicians and scientists to read and evaluate the results of the NIR test. Another advantage is that NIR is cheap and even high -performance NIR experiments compared to other spectroscopic techniques. Eventually this base isODA suitable for analyzing large samples, since near infrared light can penetrate further than infrared light.
This technology can be used in many different ways. In astronomy, NIR can be used to study new stars and to determine the age and weight of an existing star. This information helps to provide guides about how stars are formed. In medicine, infrared spectroscopy is approaching in certain diagnostic blood tests, including pulse oximetry used to measure blood oxygen concentration. The NIR can also be used as a means to assess the function of the brain and measure the heart rate in postoperative patients. There is also a lot of industrial uses for NIR, such as analysis of quality control.
