Hamilton HPLC column: Things to Know

HPLC, also known as high performance liquid chromatography is mainly developed by Hamilton Company. Pressure-stable polymeric Hamilton HPLC column is available in 17 varieties for every phase, including anion exchange, reversed-phase, cation exchange and ion exclusion separations, and two silica-based C8 and C18 columns for traditional reversed-phase separations.

 

HPLC is a powerful column chromatography method that allows a solvent to drip into a column by the use of gravity. The liquid is forced through the columns at a pressure of 400 atmospheres. That’s why it is considered to be faster than most of the normal columns and is also used extensively for column packing material. Therefore it serves as a greater area for coordination between stationary phase and molecules, offering better separation of all the components. Apart from this, other advantages of using this method is more integral and sensitive.

 

Hamilton HPLC column is basically is a biochemistry term and highly analytical. Sometimes it is impossible to distinguish or separate it from other quantifiable components and compounds. In the stationary phase, it contains chromatographic packaging materials, a pump like structure and a detector that shows the various combinations of molecules. Although the setting varies widely, depending on the interactions between stationary phase, molecules and the kind of solvent that is being used.

 

During the mobile phase, a small volume of sample is used for analysis purpose and the analyte’s movement is reduced by specific chemical and physical interactions with the stationary phase. The time interval during which a specific analyte starts to elute is known as retention time and it is a specific characteristic of this particular analyte.

 

If you want to increase the linear velocity, you must use smaller particles in columns so that the components get less time to interact and diffuse inside the column. Some of the common solvents that are being used in here are miscible combination of water, among which mostly used is methanol and acetonitrile. The water over here is not normal as some parts of water may contain buffers or salt, in order to make the separation easier. Trifluoroacetic acid acts mainly as an ion pairing agent, so it can also be used.

 

Gradient elution is another part of the entire procedure and it is mainly refinement in the mobile phase. A gradient normally consists of water with 5% methanol that can extend upto 50% in a short span of time, say around 25 minutes. The gradient composition is dependent on how much hydrophobic the analyte is.

 

Many things also depend on the phase and the nature of the analyte, especially the choice of solvents, additives and gradients. The best method for GE HPLC column is determined by carrying out many tests and analyses over a period of time and in this way, you will be able to find out which method is the best.
