How to Use an Organic Substance Microscope
By simple definition, organic substances are chemical compounds whose primary components is carbon. Either carbon rings or carbon chains comprise these compounds, along with hydrogen. Oxygen, nitrogen, and other elements are seen to constitute the compound to complete the setup.
Organic substances fall under the discipline of organic chemistry. And they play a big role in the manufacturing industry today. There are different types of organic substances. The most common of which must be the hydrocarbon group. These compounds only contain hydrogen and carbon.
Alipathic compounds are another type of organic substances, along with alicyclic compounds. But the most celebrated type of organic substances must be Polymers. Polymers are formed when carbon attaches itself to another substance, thus forming a network or a chain. There are two types of polymers - the synthetic polymers, which are artificially manufactured, and the biopolymers, which correspond to the type of polymer that occurs naturally. Synthetic polymers are also referred to as industrial polymers.
One good feature of organic substances is its molecular structure. Each of these substances has molecules distributed in a fashion unique from one another. And this is the main point of interest of organic chemists. Organic substances, especially polymers, are popular industrial components of different products being released in the market today.
Polymers are popular rubber alternatives. And since the introduction of polymers in the market, there are simply a lot of related substances that was eventually released. Good examples are nylon, polyethylene, polyesters, PVC, and Teflon, among many others. Industrial researchers and scientists are very pertinent about the structure of the organic substance under observation. And they can only accurately do the said analysis with the use of a capable microscope.
Organic scientists need fluorescence microscope to do their jobs well. Fluorescence microscope is a type of a light microscope. Its primary job is to study the innate properties of both organic and inorganic substances. This microscope uses the principles of phosphorescence and fluorescence along with absorption and reflection of light in illuminating its sample.
Fluorescence microscopes are very complex microscopes. For users to see their sample accurately, the main component of the molecular structure that is of primary interest is labeled with a fluorescent molecule. This molecule is called the fluorophore. Once that is done, the whole specimen is flooded with light following a certain wavelength. The fluorophores will then absorb the light. At this point, the illuminating light is detached from the weaker emitted fluorescent light. This particular feat is made possible with the use of emission filters.
Fluorescence microscopes are composed of an illumination source, an excitation filter, a dichroic mirror, and an emission filter. A fluorescence microscope uses either Mercury or Xenon arc discharge lamp as its main illumination source. The dichroic mirror, on the other hand, can be replaced with a dichromatic beam splitter. It is very important that both the dichroic and the filters match the emission characteristics and spectral excitation of the fluorophores that is used to mark the specimen under observation.
Almost all fluorescence microscopes being sold in the market today can also work as an epi-fluorescence microscope. Epi-fluorescence means that the observation and the excitation of the fluorescent light source are coming from the top of the specimen.
But even if fluorescence microscopes are primarily used in organic chemistry, the role it plays in biology is as crucial. It is also possible to use the principle of epi-fluorescence microscopy to determine the total count of a certain bacteria in a given water sample.
Since its development, fluorescence microscopes have effectively opened doors for a more advanced design of microscopes. Fluorescence microscopes are the forerunner of laser scanning and internal reflection microscopes.
Scientist and researches interested in organic substances are also looking into observing chemical reactions that involve organic compounds. Organic reactions require careful analysis. And this is because each reaction may result in varying electron affinity, steric hindrance, and bond strengths, which in turn, could lead to the discovery of new techniques, substances, and elements.
A popular model of a fluorescence microscope is the Nikon TE2000. What makes this microscope different from other is its orange plate. The role of this orange plate is to allow users to safely view the specimen as it effectively protects their eyes against the excited UV light emitted by the microscope.
These are the basics of fluorescence microscope and its direct relation to organic substances. To sum it up, fluorescence microscopes are the devices that allows for an accurate observation of organic substances. Without these devices, it is but impossible for scientists to discover new things and advance the current findings related to organic chemistry.
