Chromatography was invented by Russian botanist Mikhail Tsvet in 1900. He was trying to separate plant pigments and used a column of calcium carbonate to achieve separation through absorption and elution. He named his invention chromatography, which means “color writing” in Greek. Over time, chromatography has become a widely-used technique in various fields such as chemistry, biology, and forensics.
Hello and welcome! Have you ever wondered who came up with the ingenious technique of chromatography? Well, wonder no more. In 1900, Russian botanist Mikhail Tsvet revolutionized the field of science by inventing chromatography. Initially, he used this technique to separate different plant pigments and was able to achieve separation through absorption and elution, using a column of calcium carbonate. Inspired by the Greek word for “color writing,” Tsvet named his invention chromatography. In this article, we will delve deeper into the fascinating history and evolution of this technique, which today has become a staple in various fields such as chemistry, biology, and forensics.
Who Invented Chromatography
The Early History of Separation Techniques
The practice of separating mixtures into their individual components has existed for thousands of years. In ancient Egypt, alchemists used distillation to separate substances based on their boiling points. Later, in the Middle Ages, filtration was developed to separate solids from liquids. However, it wasn’t until the 19th century that chemists began to develop and refine modern separation techniques.
One of the first scientists to make significant strides in this area was Mikhail Tsvet, a Russian-Italian botanist who is credited with developing chromatography. Tsvet was studying plant pigments and noticed that the components of these pigments dissolved in different solvents at different rates. This gave him the idea to use a process of elution (where a mixture is forced through a stationary phase, with the components traveling at different rates) to separate the different pigments.
Tsvet’s early experiments used a column packed with finely divided calcium carbonate, with the pigments dissolved in a solvent that was then added to the top of the column. The solvent traveled down through the column by gravity, with the different pigments being separated out based on their affinity for the stationary phase. Tsvet published his findings in 1903, marking the birth of chromatography as we know it today.
History of Chromatography
Over the next several decades, chromatography continued to be refined and developed as a separation technique. In the 1930s, Harold McNair and Martin Kirby developed gas chromatography, which uses a gas as the mobile phase. They published their findings in 1941, but the technique didn’t become widely used until the 1950s.
Meanwhile, liquid chromatography was also being developed, with Richard Kuhn, Edgar Lederer and Heinrich Otto Wieland all making significant contributions to the field. In the 1970s, high-performance liquid chromatography (HPLC) was developed, which greatly improved the speed and accuracy of the technique.
As chromatography became more widely used in scientific research and industry, it continued to be refined and improved. Today, there are dozens of variations of the technique that are used to separate and analyze a wide range of compounds and substances.
Contributions of Martin and Synge
While Tsvet may have been the father of chromatography, the technique as we know it today wouldn’t exist without the contributions of Archer John Porter Martin and Richard Laurence Millington Synge. Martin and Synge are credited with inventing partition chromatography, which uses a liquid stationary phase and separate mobile phase to separate compounds.
Their work on partition chromatography began in the late 1930s, with Martin being interested in developing a method to separate amino acids. Together, Martin and Synge developed a technique where the amino acids dissolved in a liquid stationary phase (such as water), and were then separated out by differences in their partition coefficients.
Their work was groundbreaking, and in 1952, Martin and Synge were awarded the Nobel Prize in Chemistry for their contributions to the development of chromatography. Today, the techniques they developed are still widely used in labs around the world.

The Advancements in Chromatography
The Emergence of Gas Chromatography and High-Performance Liquid Chromatography
Chromatography has come a long way since its inception. One of the significant advancements in chromatography is the emergence of gas chromatography (GC) and high-performance liquid chromatography (HPLC). Gas chromatography involves the separation of chemical compounds based on their volatility using a stationary liquid phase and a mobile gas phase. On the other hand, HPLC separates chemical compounds based on polarity and size using a stationary solid phase and a mobile liquid phase.
The development of GC and HPLC provided significant improvements in the separation and identification of chemical compounds. These techniques became the standard in the analysis of complex samples and provided a more accurate and efficient approach in identifying chemical compounds in various industries.
Modern Day Applications of Chromatography
Chromatography continues to be an essential tool in the various industries, such as pharmaceutical, environmental, and food industry. In the pharmaceutical industry, chromatography is used in drug development and quality control. Chromatography plays a crucial role in analyzing the purity and consistency of drug compounds.
In the environmental industry, chromatography is used in the analysis of air and water pollutants. Chromatography enables the detection and separation of pollutants in complex environmental samples accurately. In the food industry, chromatography is used in the analysis of food components. Chromatography enables the separation and identification of food additives, contaminants, and other food components that affect the quality of food and food products.
Chromatography in Education and Research
Chromatography is also vital in education and research. Chromatography is an essential component of analytical chemistry and plays a significant role in advancing science and technology. Chromatography techniques are used in the separation and identification of chemical compounds in various fields such as biochemistry, forensic science, and environmental science.
Chromatography enables researchers to examine complex samples more effectively and efficiently, providing a more accurate and detailed analysis of the sample. This, in turn, helps to advance scientific research and knowledge of various fields.
