Molecules may attract or repel each other. This is called an interaction. In chemistry, an interaction refers to molecules that affect each other. Also, in many cases, interactions refer to a state in which molecules are attracted to each other. Interactions are different from molecules bonding together to form covalent bonds. If a new bond […]
It is important to analyze the structure of chemical compounds to find out what compounds are present in the solution. By analyzing the structure of these compounds, it is possible to investigate the molecules and proteins. HPLC (high performance liquid chromatography) and MS (mass spectrometry) are frequently used as methods to investigate what substances are […]
Chromatography is an experimental operation for the separation of substances. One of the most common experimental operations in chromatography is HPLC (high performance liquid chromatography). High performance liquid chromatography is used in almost every laboratory, including physical chemistry, organic chemistry, and biochemistry. Although the experiments performed vary from lab to lab, HPLC is the analytical […]
When determining the structure of a compound or detecting what compounds are present, one of the best methods is mass spectrometry (MS). When measuring a known compound, mass spectrometry can determine if it is the target compound with a high probability. Even if it is an unknown compound, mass spectrometry can be used to measure […]
One of the most widely used methods of analysis is the measurement of light. By irradiating light, it is possible to check how much of a compound is present there. The UV-visible absorption spectrum is a well-known measurement technique that utilizes light, and is used in many research institutions. In addition to detecting ultraviolet and […]
When we want to measure the state of a substance, we have to analyze it. There are various methods of analysis, and one of them is Raman spectroscopy. Molecules vibrate with each other. By examining the degree of vibration between these molecules, we can check what happens to the compound. We shine a light on […]
There are various methods of analyzing compounds. One of these analysis methods is infrared spectroscopy. This analysis method is used to analyze organic compounds to determine what kind of functional groups (substituents) are included in the compounds. However, among analysis methods, IR spectra (infrared absorption spectra) have few advantages and many disadvantages in terms of […]
A large number of laboratories use absorbance when analyzing in experimental manipulations. By measuring how much light passes through, you can measure how much of a substance is present in the solution. Alternatively, it can be used to check how far a reaction has progressed. When experimenting with biological systems, we frequently use absorbance to […]
Chromatography is a method of separating substances completely. There are several types of chromatography, of which column chromatography is the most frequently used in laboratories that deal with organic compounds. A type of adsorption chromatography is column chromatography. It uses an adsorbent called silica gel to separate several organic compounds that are mixed together. Column […]
In a laboratory that mainly focuses on the synthesis and separation of organic compounds, thin-layer chromatography (TLC) is an analytical technique that is used every day. Typically, chromatography is used to separate substances. Of course, thin-layer chromatography can also separate compounds. However, rather than separating a large number of compounds that have been synthesized or […]
