High-Pressure Liquid Chromatography

The term “high-pressure liquid chromatography” refers to the process of column chromatography that helps pump a sample mixture in a solvent at high pressure.

The study focuses on high-pressure liquid chromatography to explore the concept of the same. The purpose of the study is to discuss the uses of high-pressure liquid chromatography. Moreover, the high-pressure liquid chromatography machines will also be evaluated in this study. The idea is to determine the pressure while pumping an analyte into a solvent and so is the high-pressure liquid chromatography. The study ensures the significant uses of the same for medical utilities. However, ultra-high-pressure liquid chromatography will also be explored through the course of this study. This is used in identifying each component of the mixture.       

High-Pressure Liquid Chromatography 

High-pressure liquid chromatography (HPLC) is a form of liquid chromatography that is utilised to segregate the individual components present in the mixture and dissolved them in the sample solution thereafter. This process is based on the pumping of the mobile phase with the help of a packed column under high pressure. However, it turns out to be a chromatographic method, which is further utilised to alienate the compounds in biochemistry and analytical chemistry for purifying or quantifying the individual components. In recent times, the pharmaceutical industries in India can detect the impurities within the compound of the mixture and thereby purify water through high-pressure liquid chromatography. It is an analytical technique that is used to trace the components in the mixture. The working principle of high-pressure liquid chromatography undergoes several phases to make sure it can properly detect the impurities within the compounds. At the outset, the sample mixture is separated and tested and is then sent to a stream of mobile phase percolation through a column. 

Ultra high-pressure liquid chromatography 

Ultra high-pressure liquid chromatography (UHPLC) appears to be one of the most powerful tools in analytical chemistry. It is capable of separating, identifying and quantifying the compounds in a more precise way. Assuming the significance of high-pressure liquid chromatography, the further focus has been made on the advancements of column technology while considering speed, sensitivity and resolution in liquid chromatography. Several kinds of research have been made based on the design capabilities of liquid chromatography of columns having smaller particles of 1.7 microns. The idea gives rise to the formation of ultra-high-pressure liquid chromatography to achieve high performance. This technique is similar to HPLC and is used to segregate different constituents of a compound within the mixture. In ultra-high-pressure liquid chromatography, particle size less than 2 micrometres is used offering better segregation than HPLC. These smaller particles call for a high pump pressure making UHPLC much more efficient with higher resolution and fast analysis. However, this chromatography technique is limited to separating polysaccharides or inorganic ions. This instrument is also not compatible with the non-polar solvents due to a lack of a universal detector within the instrument.  

High-pressure liquid chromatography machine 

A high-pressure liquid chromatography machine tests and separates the compounds from the mixture and sends them to a mobile phase through the process of percolation. There are several types of columns available with solvents ranging from small to big particle sizes. The machine usually uses a UV detector for the analysis and the sample undergoes a clear colour-less glass cell during the analysis and that is called a flow cell. The high-pressure liquid chromatography is designed based on the types of HPLC columns, Bead size, Internal diameter, Length and Pore size. The HPLC columns come in the range of different lengths and diameters and can be manipulated according to the requirements to enhance the efficiency of the machine. However, the Indian HPLC service provider, Thermo Fisher Scientific makes the Thermo Vanquish Horizon UHPLC system to provide better throughput for the applications calling for high-end UHPLC. It is turned out to be ideal for the R&D labs.    

High-pressure liquid chromatography uses 

  • High-pressure liquid chromatography has several benefits that help users come up with a solution to make a significant mark in analytics chemistry. 
  • The benefits of an HPLC system reflect on the control of chromatography instrumentation and provide security features as well as data management. 
  • High-pressure liquid chromatography is used in Biochemistry for analysing the constituents of a compound. 
  • It is useful in separating and identifying nucleic acids, amino acids, proteins, pesticides, antibiotics or other inorganic substances. 
  • Because of its versatility, it is used in a range of scientific and industrial applications such as environmental, chemicals, forensics, pharmaceuticals etc. 
  • Applications of HPLC also include water purification, pre-concentration of the trace components, ion-exchange chromatography of proteins, detection of impurities in the pharmaceutical industries etc.  

    Conclusion 

    It can be concluded from the study that high-pressure liquid chromatography acts as a driving factor in medical applications with the concept to segregate the compounds in the sample mixture. The study discusses the functions of liquid chromatography to detect the impurities in the compounds. However, the concept of ultra-high-pressure liquid chromatography has been widely covered to show the latest advancement in liquid chromatography. It is concluded that UHPLC delivers better separation than HPLC for particle size less than 2 micrometres. The high-pressure liquid chromatography provides faster analysis as shown in this study.
