1. Introduction

In the vast landscape of analytical techniques such as Spectroscopy, Mass spectrometry, HPLC also emerges as a beacon of precision and efficiency. As we navigate through the applications of HPLC, it becomes evident that its significance extends far beyond mere analysis.

To understand the magic behind HPLC, we must first grasp the principles of chromatography. This section demystifies the science, shedding light on the key components that constitute an HPLC system. We have discussed basic principles of chromatography in separate article. Please see for more details. [Link]

The chromatography is based upon competitive interactions of molecules in the given mixture with stationary phase (for example; silica gel). Here the mobile phase (solvent) helps the molecules of given mixture to pass through the column. This results in the separation of the molecules form the given mixture.

2. Principle of HPLC

Basically, this technique separates the individual compound from given mixture of compound by the help of standard column chromatography and then analyses each compound and showcase in the form of spectrum. This spectrum gives an idea that how many unique compounds present in the given mixture. To understand this technique, please see the following diagram which shows basic component of HPLC instrumentation. The involved steps are described below;

Figure 1: Principle of HPLC

Step 1: Solvent is passed through the column by using pump. The solvent preferably chose as mixture of solvent which are differ in their polarity. The pH of mobile phase is adjusted by addition of various buffers and additives such as acetic acid, formic acid and ammonium salts. 

Step 2: Given sample is injected by using sample injector.

Step 3: Both solvent and given mixture of compound passes through column simultaneously. The column can be of verity of types such as, Normal phase column, Reverse phase column, Ion exchange column, and Size exclusion column.

Step 4: During this process the mixture of compounds gets separated based upon their interactions with stationary phase.

Step 5: The separated fractions then analyzed by a detector. And waste in collected. This also can be collected separately to isolate the pure fractions for compounds.

Step 6: Finally, the detector translates the data which is recorded in the form of spectrum. This gives an idea that how many different organic compounds present in the given material.

3. Applications of HPLC

3.1. Pharmaceutical Proficiency:

HPLC is a key player in the pharmaceutical industry and used for analysis of a wide variety of samples. It is an excellent method for inspection of the purity of new drug candidates, monitoring variations or the scale up of synthetic procedures, in-process testing for developing new formulations, and quality control/assurance of final drug products.

3.2. Environmental Excellence:

Delve into the environmental sector, where HPLC plays a crucial role in monitoring and analyzing pollutants. For example; HPLC is helpful in the detection of phenolic compounds in drinking water. Environmental samples can consist of waste water, drinking water, soil, sediments etc.

3.3. Food and Beverage Industry:

 HPLC has essential role in the food and beverage industry due to its capability to separate, detect, and quantify several compounds within complex mixtures or sample.

This includes analysis and quantification of food additives, preservatives, and contaminant. HPLC also useful in analysis of nutrients, flavor and aroma of the sample, packaging safety. In beverage industry HPLC is used for detection and quantification sugars, acids, alcohol, and other components that affect flavor and quality.

3.4. Clinical Precision in Healthcare:

HPLC is essentially used in diagnostic testing, biomarker analysis, and therapeutic drug monitoring by using blood and other medical samples from patients. When researching specific diseases and disorders, scientists will often take biological samples from existing sufferers for analysis.

3.5. Advances in Research and Academia:

HPLC propels scientific research forward. From analyzing complex biological samples to exploring new analytical methods, witness how HPLC underpins breakthroughs in academia. HPLC also used as tool for monitoring the chemical reaction in research laboratory. This is even used for determination of undesired impurities and reaction intermediates which are formed during the chemical reactions. Eventually, HPLC also useful to understand reaction mechanism in organic chemistry. 

3.6. Forensic Science:

This includes drug testing to the analysis of crime scene evidence. Therefore, HPLC serves as an indispensable tool in forensic investigations.

3.7. Petrochemical Precision:

The role of HPLC in the petrochemical industry is the analysis of crude oil to ensure the quality and compliance of fuels and lubricants.

3.8. Metabolomics:

Enter the realm of metabolomics, where HPLC is revolutionizing the study of small molecules in biological systems. The HPLC is often coupled with mass spectrometry enables the comprehensive analysis of metabolites, paving the way for breakthroughs in personalized medicine and disease understanding.

3.9. Nanotechnology:

The intersection of HPLC and nanotechnology, where minute particles and structures are analyzed with unprecedented precision. The HPLC method is useful in analysis of molecules in nano particles in different physical conditions, over different periods of time. Hence synergy is driving advancements in material science, electronics, and the development of novel nanomaterials. For example; HPLC is one of the important techniques used for determination of released drug content out of nano drug formulations, in different physical conditions and time.

In addition to its current applications, the world of HPLC is witnessing continuous innovation, pushing the boundaries of what is achievable.
