Pros And Cons Of Hplc

High performance liquid chromatography equipments have immensely become popular these days. These are increasingly being used by life sciences and pharmaceutical organizations their research purposes. Liquid Chromatography is basically a separation technique which involves injecting a small amount of liquid sample into a tube that is filled with porous particles. The individual components are then transported with the packed tube. HPLC parts have been widely used because of the many advantages these offer, the foremost being higher efficiency in terms of separating complex technical mixtures. HPLC is also referred to as UPLC, RRLC, UFLC, and RSLC. Sometimes HPLC is also known as High Pressure Liquid Chromatography.
Discussed below are both advantages and disadvantages of HPLC equipments –
Advantages
With HPLC you can conduct analysis in short time and still achieve a higher degree of resolution, this means that the elements in a sample can be separated more completely.
Allows ...
... stationary columns to be reused a number of times without requiring that they be regenerated, and the results of analysis are more highly reproducible
Automatic instrumentation and quantitation.
Using HPLC researchers can analyze diverse kinds of compounds. Also, the samples separated using HPLC do not require to be passed through solvents such as methanol and hexane.
Adaptability to large scale preparative procedures
HPLC columns can be reused with re-packing or re-generating
Disadvantages
HPLC Accessories are quite costly
In addition, the high quality solvents (mobile phase) and the fact that most need to be degassed and filtered before they can be used also adds to the expense and the time to set up an analysis.
There is also no universal detector for all substances analyzed.
A standard or set of standards and control specimens must also be performed with every run.
Operating an HPLC system is a complex task. One needs to have many consumables, such as solvent, filters and plastic tubing. Pump seals and rotors must also be replaced on a routine basis for optimal operation.
HPLC columns have a limited lifespan approximately 500 to 2000 injections. Further, these must be replaced after certain period of time replaced for proper chromatography.
Moreover, columns are the most expensive item in an HPLC system, and depending on the composition of the packing material, these can cost you anywhere around $300 to $900.
HPLC systems at times can be quite challenging to manage. There may be situations when the systems leak. These systems need periodic maintenance in order to function smoothly. At regular intervals, pump seals, rotors and columns need to be replaced.
In case you are looking for an HPLC replacement parts provider, Hitachi HPLC could be the best option for you. The Company offers all sorts of HPLC parts, HPLC component parts, Hitachi HPLC replacement parts and even Waters HPLC parts. You will get the finest quality Agilent hplc parts from the company at affordable rates.
