In the last few years, scientific methods have significantly improved due to development in technology. Every day, new methods are brought into place, which makes it easy for scientists to handle various projects with ease. This explains why scientists and laboratory experts are coming up with comprehensive analysis and findings of various experiments. One of the most advanced laboratory tools is a spectrometer.
What Is A Spectrometer?
A spectrometer is a scientific device that is used in measuring light wavelengths over a wide range of electromagnetic spectrum. In most cases, spectrometers are used in the analysis of sample material in the university or medical laboratory.
Light from the source is transmitted through the sample under consideration and is either reflected, refracted, or absorbed. The experimental changes that will occur to the incident light after interacting with the sample will be used to reveal the characteristics of the sample under consideration.
1. Most of the laboratory samples have been tested using a spectrometer in a laboratory experiment process called spectroscopy. However, it is important to highlight that there are different types of spectroscopy some of which have been discussed below.
Absorption Spectroscopy
This is a technical method that uses a benchtop NMR spectrometer to test the properties of a specific laboratory sample. It works by absorbing the light wavelength that is produced by the source. It is common knowledge that sample molecules will be very active after being exposed to light molecules. The excitation levels of the molecule provide finer details above the wavelength of the light. This process is used in testing energy transfer among particles of a particular sample.
2. Infrared Spectroscopy
Measuring the vibrations of the atomic bonds in a specific sample is very important. Understanding these forces and vibrations may explain how apart they are, which may help in explaining whether a particular laboratory sample is a metal or a non-metal sample. Infrared spectroscopy, which uses a desktop NMR, is essential in testing the vibration of inter-atomic bonds in a laboratory sample. Studies show that infrared spectroscopy can as well be used in testing the number of absorbing molecules in a specific sample.
3. X-Ray Spectroscopy
X-ray spectroscopy is a very common sample testing and analysis procedure in the medical sector. It is essential in drug testing and understanding the energy generated by particles in a particular sample. In most cases, low field NMR spectrometer is used in X-ray related testing because they produce less energy, which is less likely to affect the sample medical products under considerations. The energy generated by the sample particles is a clear indication of the amount of energy expected from the drug sample.
4. Ultraviolet Spectroscopy
Ultraviolet spectroscopy is a high-level sample analysis technique. It is mostly used in chemical laboratories or large scale drug processing and testing laboratories. The sample chemical under consideration is exposed to ultraviolet light energy. The particles of the chemical under consideration will absorb the energy from the ultraviolet light and get excited. The energy absorbance rate of the particles is used in determining the mass and density of the chemical sample.
5. Laser Spectroscopy
As the name suggests, laser spectroscopy uses light energy as a radiation source that is used in the sample testing procedure. Laser spectroscopy is used in measuring the interaction of light molecules with those of the sample molecules. One of the main benefits of this sample testing method is that it has a higher resolution and sensitivity as compared to other testing procedures out there in the industry.
What Next?
You can buy a process spectrometer for various NMR spectrometer applications in the industry and use any of the spectrometer processes discussed above. In most cases, most of the NMR spectrometers range from 60MHz to 100MHz. Therefore, you need to know the frequency of the light intensity you will need for your sample analysis before deciding on the spectrometer to purchase. 60 MHz benchtop NMR spectrometers are the most common spectrometers out there in the industry.
