Methods of investigation

Over the years, a great number of methods have been developed that are currently able to detect different macromolecules and their concentrations by way of very accurately.

Automatic fraction and sample
collector for chromatography

Among these methods is the high performance liquid chromatography (HPLC), is a technique used to separate the components of a mixture based on different types of chemical interactions between the analyzed substances.
One of its important future projections is that then of separate of the components, is passed to its posterior quantification, what in the field of health it is very useful for detect of diseases and an early diagnosis.
This semester I have been reading any papers scientific of methods of detection, among which are immunoassays, capillary electrophoresis, electrochemical techniques and different chromatographies, and I chose the HPLC because is the most used in the investigations, having high results.

For human welfare is quite promising because an early diagnosis would help better treatment for diseases.
But as methods has the time disadvantage, a HPLC can take between hours to days, for example this methods would not be useful in doping test, instead, an electrochemical technique would be better in this case, everything will depend on the purpose of the study.
