Preventing Leaks In HPLC Analyses  

Leaks are a common problem in HPLC analyses. To minimize leaks in your system, avoid interchanging hardware and fittings from different manufacturers. Incompatible fittings can be forced to fit initially, but the separation may show problems and repeated connections may eventually cause the fitting to leak. If interchanging is absolutely necessary, use appropriate adapters and check all connections for leaks before proceeding. Highly concentrated salts (>0.2 M) and caustic mobile phases can reduce pump seal efficiency. The lifetime of injector rotor seals also depends on mobile phase conditions, particularly operation at high pH. In some cases, prolonged use of ion pair reagents has a lubricating effect on pump pistons that may produce small leaks at the seal. Some seals do not perform

HPLC (high performance liquid chromatograph ) Instrumentation  

Main components in an HPLC system include the solvent reservoir, or multiple reservoirs, a high-pressure pump, a column, injector system and the detector.

The reservoir holds the solvent, which is referred to as the mobile phase because it moves. There are usually a minimum of two reservoirs in a system, with each holding up to 1000 cc of solvent and usually fitted with a gas diffuser through which helium can be bubbled. A pump is used to generate a specified flow of the mobile phase. Although manual injection of samples is still possible, most HPLCs are now fully automated and controlled by computer. The injector, or auto sampler, introduces the solvent into a phase stream that carries the sample into the high pressure (up to 400 bar) column, which contains specific packing material nee

principle of hplc:High Performance Liquid Chromatography (HPLC)  

High performance liquid chromatography (HPLC) has become a very versatile and powerful separation and analytical method over the years. It is an advanced form of liquid chromatography (LC).
Instead of introducing the solvent into the column and allowing it to drip down under the influence of gravity, in HPLC the sample is forced through the column under high pressures of nearly 400 atm, resulting in faster and more efficient separation.
This technique is also called high pressure liquid chromatography.

The Principle of HPLC
HPLC follows the same basic principle as chromatography. Different components in the sample have varying affinities to the adsorbent material. This causes a difference in the flow rate for each component which leads to their separation as they come out of the column.

Principle of HPLC:High Performance Liquid Chromatography (HPLC) : Principle, Types, Instrumentation and Applications  

Chromatography is a technique to separate mixtures of substances into their components on the basis of their molecular structure and molecular composition. This involves a stationary phase (a solid, or a liquid supported on a solid) and a mobile phase (a liquid or a gas). The mobile phase flows through the stationary phase and carries the components of the mixture with it. Sample components that display stronger interactions with the stationary phase will move more slowly through the column than components with weaker interactions. This difference in rates cause the separation of variuos components. Chromatographic separations can be carried out using a variety of stationary phases, including immobilized silica on glass plates (thin-layer chromatography), volatile gases (gas chromatography

Mobile Phase (eluent) In Column Chromatography  

The mobile phase or eluent is either a pure solvent or a mixture of different solvents. It is chosen so that the retention factor value of the compound of interest is roughly around 0.2 - 0.3 in order to minimize the time and the amount of eluent to run the chromatography. The eluent has also been chosen so that the different compounds can be separated effectively. The eluent is optimized in small scale pretests, often using thin layer chromatography (TLC) with the same stationary phase.
There is an optimum flow rate for each particular separation. A faster flow rate of the eluent minimizes the time required to run a column and thereby minimizes diffusion, resulting in a better separation. However, the maximum flow rate is limited because a finite time is required for the analyte to equi

principle of hplc:How Does High Performance Liquid Chromatography Work?/what is Detector,Chromatogram?  

How Does High Performance Liquid Chromatography Work?

The components of a basic high-performance liquid chromatography [HPLC] system are shown in the simple diagram in Figure E.
A reservoir holds the solvent [called the mobile phase, because it moves]. A high-pressure pump [solvent delivery system or solvent manager] is used to generate and meter a specified flow rate of mobile phase, typically milliliters per minute. An injector [sample manager or autosampler] is able to introduce [inject] the sample into the continuously flowing mobile phase stream that carries the sample into the HPLC column. The column contains the chromatographic packing material needed to effect the separation. This packing material is called the stationary phase because it is held in place by the column hardware.

Evaporative Light Scattering Detector (ELSD)  

An evaporative light scattering detector (ELSD) is a detector used in conjunction with high-performance liquid chromatography (HPLC). It is commonly used for analysis of compounds where UV detection might be a restriction and therefore compounds does not very efficient absorb UV radiation, such as sugars, antivirals, antibiotics, lipids, phospholipids, terpenoids, and alcohols. ELSDs fall under the category of general-purpose detectors, similar to refractive index detectors (RI).
