HPLC Role in Pharmaceutical Analysis

High-performance Liquid Chromatography (HPLC) is an incredible analytical method with a broad range of applications across different industries. With its flexibility and performance, HPLC is employed in various pharmaceutical applications, research, and clinical laboratories. HPLC plays a pivotal role in the separation and analysis of pharmaceutical raw materials and drugs.  It is an essential tool in pharmaceutical applications like purity analysis and evaluating formulations. In this blog, we discuss the view of HPLC’s role in pharmaceutical analysis. 

High-Performance Liquid Chromatography (HPLC) in Pharmaceutical Analysis

There are various methods for analyzing pharmaceutical compounds, and HPLC is the best choice for the analysis of these compounds. HPLC has become a standard practice in the pharmaceutical industry for various samples. It is used to check the purity of new drug candidates, conduct in-process testing for developing new formulations, track changes or the scale-up of synthetic procedures, and control the quality of final drug products. HPLC is also used to analyze many natural products, plant extracts, and herbal medicines. Aral Research is a trusted HPLC lab test in Ahmedabad for pharmaceutical analysis. Our HPLC testing lab is equipped with the latest advanced instruments for reliable results and the lowest turnaround time. 

How is HPLC Used for Pharmaceutical Analysis? 

High-performance Liquid Chromatography (HPLC) is renowned for its precision and accuracy. Despite its high costs, HPLC is an ideal method for the accurate identification and quantification needed for pharmaceuticals. HPLC is used to analyze pharmaceutical products such as drugs and medicines for the ingredients they contain. It is employed to separate, quantify, and identify different components along with their quantities. This allows manufacturers to get valuable insights into the drug properties and how each component’s quantities impact the overall performance and strength of the product. Moreover, it also allows us to identify and quantify any impurities within the pharmaceutical products. 

HPLC Pharmaceutical Applications: 

  • Determination of shelf life of drugs and pharmaceuticals. 
  • Identification of active ingredients 
  • Tablet dissolution of pharmaceutical dosage forms
  • Pharmaceutical quality control 

The process of creating a new pharmaceutical drug can be divided into 3 main stages: 

  • Drug discovery
  • Drug development
  • Drug manufacturing 

HPLC plays a pivotal role in all these stages, including applications such as separation and quantification of different analytes through analytical HPLC or isolation & purification of compounds through preparative HPLC.  Aral Research is one of the most trusted HPLC testing labs in Ahmedabad, offering exceptional services for the pharmaceutical industry in the identification and isolation of active ingredients, quality control of raw material formulations and determination of the shelf life of finished products. This comprehensive application of HPLC ensures that all aspects of drug creation are thoroughly monitored and controlled. To discuss your analytical requirements, call us today.

Difference Between Liquid Chromatography & Gas Chromatography

Chromatography is the process of separating and identifying compounds from a sample of interest. It is an indispensable tool for isolation and purification of compounds. Chromatography is classified based on the physical state of the mobile used: Liquid and gas chromatography. How are these two chromatography methods different? Let’s find out!

What is Liquid Chromatography? 

Liquid chromatography is a separation method that is used in labs to separate sample mixtures based on the interaction between the individual molecules. The HPLC lab test in Ahmedabad uses this technique in the liquid mobile phase, where the sample mixture is blended with liquid. It is allowed to pass through a column filled with the stationary phase or a solid sheet of the stationary phase. The liquid chromatography method separates and analyzes high thermal stability and non-volatile and challenging vapourization. It is extensively used for quantitative analysis of pharmaceutical products and laboratories.

What is Gas Chromatography? 

Gas chromatography is another chromatography technique that analyzes volatile samples, which are gases at room temperature, and a gaseous mobile phase that carries the sample through a solid phase. The sample flows through the gas system, which is gasified before entering the chromatographic column with a filler for effective separation. 

Difference Between Liquid Chromatography & Gas Chromatography

  • Mobile Phase Used: The primary difference between HPLC and GC is the mobile phase used. LC uses a solvent for the mobile phase in which the compounds’ polarity, complexity, and solubility determine the solvent to be used. Meanwhile, GC uses an inert or unreactive gas. 
  • Separation Methods: For the HPLC service in Ahmedabad, the separation of the compounds is determined by the interaction between every compound in the mixture in the mobile and stationary phases. In gas chromatography, the separation depends on the respective volatility of every compound in the mixture. 
  • Temperature: Due to the volatility of the sample, gas chromatography needs to be done at higher temperatures than high-performance liquid chromatography. The column temperature of GC is somewhere between 150 to 300 degrees Celsius, while for HPLC, it is done at room temperature. 
  • Difference in Applications: Gas chromatography is typically used to measure oils, air samples, organic compounds, and pharmaceutical drugs. While HPLC for inorganic ions, proteins, peptides, lipids and vitamins. 

It is crucial to know the difference between liquid and gas chromatography so you can select the most appropriate method for the sample. Apart from choosing the right method, achieving accurate results during analysis is essential, which Aral Research can help you.
