The Different Types of Chromatography
There are four main types of chromatography. These are Liquid Chromatography, Gas Chromatography, Thin-Layer Chromatography and Paper Chromatography.
Liquid Chromatography is used in the world to test water samples to look for pollution in lakes and rivers. It is used to analyze metal ions and organic compounds in solutions. Liquid chromatography uses liquids which may incorporate hydrophilic, insoluble molecules.
Gas Chromatography is used in airports to detect bombs and is used is forensics in many different ways. It is used to analyze fibers on a persons body and also analyze blood found at a crime scene. In gas chromatography helium is used to move a gaseous mixture through a column of absorbent material.
Thin-layer Chromatography uses an absorbent material on flat glass or plastic plates. This is a simple and rapid method to check the purity of an organic compound. It is used to detect pesticide or insecticide residues in food. Thin-layer chromatography is also used in forensics to analyze the dye composition of fibers.
Paper Chromatography is one of the most common types of chromatography. It uses a strip of paper as the stationary phase. Capillary action is used to pull the solvents up through the paper and separate the solutes.

What are the factors that affect leaf chromatography?
Factors that affect leaf chromatography include the polarity of the solvent used, the size and shape of the molecules being separated, the pH of the solvent, and the temperature at which the chromatography is performed. These factors can impact the rate at which the molecules move through the chromatography medium and the resolution of the separation.
Does pepsin affect pH?
Pepsin doesn't affect the pH but it is active in an acidic environment.
Why ro feed ph?
There is no real optimal pH. The best pH from rejection point of view for thin film composite membranes.
How iron affect pH?
The pH is not affected by iron (Fe).
What jobs use affinity chromatography?
Chromatography is the use of specially formulated paper to test the pH of a solution. Jobs using chromatography include chemists, researchers, students, pharmaceutical technicians, aquarists, and pool maintenance personnel.

HOW DOES ZINC SULFIDE AFFECT pH?
It will raise the pH.
How does clay leaching affect pH?
Clay leaching do not affect pH
Why ro feed ph?
There is no real optimal pH. The best pH from rejection point of view for thin film composite membranes.
How does pH affect plants?
pH affects the availability of nutrients.
How iron affect pH?
The pH is not affected by iron (Fe).

How does the ph affect cheese?
When the PH is increased, the cheese usually softens.
How does activated carbon affect pH?
as co2 increase pH decreases
How does substrate concentration and pH affect enzymes?
Substrate concentration will affect enzymes because substrates are specific to enzymes. The pH will affect enzymes because certain enzymes will work better in certain pH levels.
What is the pH value of calcium?
Calcium chloride does not affect pH so a solution of it would have a pH of 7
