This illustration gives you the detailed information on classification of chromatographic methods. Chromatographic methods had 3 main types that is based on stationary, stationary phase format & mobile phase.

To increase students' awareness of possible invisible pollutants in drinking water sources, students perform an exciting lab requiring them to think about how solutions and mixtures exist even in unsuspecting places such as ink. They use alcohol and chromatography paper to separate the components of black and colored marker ink. Students witness first-hand how components of a solution can be separated, even when those individual components are not visible in solution.

This lesson has students solving the mystery of a note by conducting chromatography. They will test different washable markers and see that different marker colors are made up of various pigments. They will compare and contrast the note chromatography with other chromatography results from a variety of markers.

This is a laboratory investigation where students will use the scientific method to solve a new, experimental question in chromatography.

The topic is 'Classification of Chromatography'. Powerpoint application has been used for making the infographic. It briefly explains what is chromatography and its various types.

I have made my illustraions using 'Power Poin Presentation'. It includes the information about all three types of classifications of chromatographic method with examples. It also contains some explaination about different types of chromatographies. Ihave also added the name, refernces and sources at the bottom.

Students perform DNA forensics using food coloring to enhance their understanding of DNA fingerprinting, restriction enzymes, genotyping and DNA gel electrophoresis. They place small drops of different food coloring ("water-based paint") on strips of filter paper and then place one paper strip end in water. As water travels along the paper strips, students observe the pigments that compose the paint decompose into their color components. This is an example of the chromatography concept applied to DNA forensics, with the pigments in the paint that define the color being analogous to DNA fragments of different lengths.

Students observe multiple examples of capillary action. First they observe the shape of a glass-water meniscus and explain its shape in terms of the adhesive attraction of the water to the glass. Then they study capillary tubes and observe water climbing due to capillary action in the glass tubes. Finally, students experience a real-world application of capillary action by designing and using "capillary siphons" to filter water.

This activity is a classroom investigation where students separate pigment in dyes in order to learn about mixtures and solutions. They use chromatography to design and experiment with a single variable to answer a question about which ink will separate the most - has the greatest variety of pigment.

This activity is a lab investigation where students design an experiment to extract pigments (AKA chromatography) from different colored, water soluble markers.

In this chemistry lab experiment, students explore the properties of color using chromatography. Students will observe and compare color patterns to differentiate compositions of various colors. Students gather data on color patterns and develop new experimental questions based on their data.

We now know how to analyze pure compounds, but what if we have a mixture? Spectrophometry becomes quite complex when dealing with multiple species of compounds at once. In order to purify a compound we can separate if from a mixture based on its intrinsic chemical properties. Remember that fluorescein is negatively charged at a pH above pKa of the carboxyl group. We can take advantage of this fact and use its attraction to positive charges to separate it from other molecules. In ion-exchange chromatography, we will use a stationary phase with a positive charge, allowing negatively charged molecules to bind and positively charged species to flow through. We can then disrupt this interaction and retrieve our now-purified molecule, and use spectrophotometric analysis of our purified fractions to determine how well we were able to separate our molecules.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"A team of researchers based at West Virginia University has devised an innovative way to potentially monitor enzyme activity in vivo using electron paramagnetic resonance imaging. The method could provide new insights into the molecular underpinnings of many types of disease. The team specifically focused on tracking enzymatic dephosphorylation. Abnormalities in dephosphorylation have been linked to disorders ranging from cancer to Alzheimer disease. Monitoring such malfunction in vivo can provide crucial details into disease state and progression, but direct measurement of enzyme activity within a living organism remains extremely challenging. Many imaging approaches that might be used for this purpose are hampered by concerns such as low sensitivity and penetration depth. Such limitations prompted the researchers to turn to EPRI – a method with high intrinsic sensitivity and specificity..."

This course covers the general principles of separation by equilibrium and rate processes. Topics include staged cascades and applications to distillation, absorption, adsorption, and membrane processes. Phase equilibria and the role of diffusion are also covered.
