Pharmaceutical analysis is a wider term which can be defined in various ways. This phenomenon is used for identification, determination, separation, purification, and structure elucidation of the given compound used in the formulation of pharmaceutical products. The pharmaceutical components is used to pharmaceutical analysis is done, are normally active pharmaceutical ingredients, pharmaceutical excipients, contaminants present in pharmaceutical products, or drug metabolites. Pharmaceutical analysis can be done by using various analytical techniques.

Analysis of pharmaceutical product in different areas;

The goal of green analytical science is to employ systematic technologies that generate less toxic waste, which are safer to applicable and better for the environment. the development of latest analytical techniques changing an old strategy to combine methods that either employ less risky synthetic compounds or use little amounts of risky synthetic substances.

This area is related to physical research that examines the relationship between control, as a quantifiable and quantitative consideration, and observing the changing properties of organic compounds, with control being viewed as either an indirect result of a specific compound change or in a different way.

Analytical chemistry studies and uses instruments and methods used to separate, identify and quantify of matter. In practice separation, identification or quantification may constitute the entire analysis or be combined with any other method. Modern analytical chemistry is deals with instrumental analysis.mostly analytical chemists focus on a single type of instrument. Academics tend to either focus on current applications and discoveries or on new methods of analysis. Spectroscopy based on the differential interaction of the analyte along with the electromagnetic radiation. Chromatography, in which the analyte is separate out from the rest of the given sample so that it may be measured without interference from other compounds.

Mass Spectrometry is an analytical method that ionizes chemical species and separates of ions based on their mass to charge ratio. In order to measure the characteristics of individual molecules, a mass spectrometer convert them in to ions so that they can be moved about and replace by external magnetic fields and electric fields.Mass spectrometry has been enhanced with advanced features related the fields in life sciences and medical analysis of the various sorts of explanatory methods utilized as a part of drug discovery and advancement. A mass spectrum is a plot of the ion signals as a function of the molecular mass-to-charge ratio. These spectra are use to determine the elemental or isotopic signature of a given sample, the masses of particles and of molecules, and to elucidate the structures of chemical molecules, such as peptides and another chemical compounds.

In chip based chromatography separation techniques we use micro fabricated separation device. The availability of the fused-silica capillary marked a significant breakthrough for gas chromatography and all gas chromatographs manufactured were we use fused silica capillary columns for separation. Fused-silica capillaries have an abundant contribution to the developments of other micro separation methodology like supercritical fluid chromatography. The success of one separation technique relies on sample introduction technologies their separation column and sensitive detectors that can preserve chromatographic fidelity of high resolution chromatographic peaks.

The HPLC-Chip is made of biocompatible polyimide and the functionality of this chip is equivalent to conventional Nano spray LC/MS. Monoliths make by single rod of porous material with several unique features in terms of permeability and efficiency

The HPLC methodology applicable for the analysis of biological samples makes it possible for the identification of many metabolites. Samples collect from two human embryos culture medium were analysis by high-pressure liquid chromatography–mass spectrometry (HPLC–MS). They work based on the principle that many microorganisms have their own unique mass spectral signature based on the particular proteins and peptides that are present in the cells. Identification of unknown peaks in gas chromatography (GC-MS)-technique based discovery metabolomics is challenging, and remains necessary to permit discovery of novel or unexpected metabolites that may allergic diseases processes and further our understanding of how genotypes related to phenotypes.

Chromatography is a method of separation of compounds from a mixture. The technique is both analytical and preparative and is employed most widely applicable in industries as well as in laboratories. Chemical analysis is mostly done all over the world with chromatography or any other many techniques relate to chromatography. Chromatography is a physical technique based on state of separating compound and has a vast application in chemical field starting from basic analytical chemistry to forensic science.

UHPLC (Ultra-HPLC) or UPLC (Ultra Performance Liquid Chromatography) is now being adopted in industrial labs, especially the pharmaceutical industry for analytical application due to its high speed, high resolution and solvent saving. A UHPLC technique uses a sub-2micron column as it minimize the analysis time by 80% and save the mobile phase consumption by a huge amount compared to the conventional HPLC. In addition, the much shorter run time significantly minimize UHPLC method development scouting time. Micro and Nano HPLC ensure that high levels of flow rate flexibility and reproducibility.

High Performance Liquid Chromatography (HPLC) technique is a non-destructive procedure for resolving a complex mixture into its individual fractions or compounds. It is based on the differential migration of solutes with the solvents. The solutes in a mobile phase go through stationary phase. Those solutes with a high affinity for the mobile phase will spend more times in this phase than the solutes that prefer the stationary phase. As the solute rise up through the stationary phase and they separate. The process is called chromatographic development. The fraction with greater affinity to stationary layer travels slower and shorter distance while that with less affinity travels faster and longer distance.

The following techniques are used for separation:

The biophysical hyphenated technique is developed from the coupling of a separation technique and an on-line spectroscopy detection technology. Several remarkable improvements in hyphenated analytical methods over the last two decades have significantly broadened their applications in the analysis of biomaterials, especially natural product, pre-isolation analyses of crude purification or fraction from various natural sources, isolation and detection of natural products, chemical fingerprinting, testing of herbal products, de-replication of natural products, and metabolomics.

Isolation and purification can be achieved by various modern hyphenated methods

HPLC is the most versatile of all chromatography techniques but also the most complex. It was first made available in the laboratory during the 1970s and is currently used for the analysis of life sciences related organic compounds amino acids, peptides, proteins, carbohydrates, lipids, nucleic acids and related compounds, vitamins, hormones, and drugs.

HPLC can be coupled with following detectors

HPLC can be applicable in both qualitative and quantitative applications that are for both compound quantification and identification. Normal phase HPLC is rarely used now, almost all of HPLC separation can be performed in reverse phase. Reverse phase HPLC (RPLC) is ineffective for only a few separation types.

HPLC is applicable for

Fingerprinting is a quality control process that builds upon spectroscopic and chromatographic technology. It is differ from the traditional quality control model in the sense that fingerprinting looks at the “complete information” or comprehensiveness of the chromatograph, and displays integrated quality information data. HPLC techniques are applicable for purification and separation of various biological samples. The analyzed samples are under going to sequencing studies either manually or using different software’s. This is studied as Data mining and sequencing analysis. HPLC is also used for the characterization of various metabolites.

HPLC is a very common method for metabolic analysis. With the discoveries of electrospray ionization, HPLC is used with mass spectroscopy. HPLC has lower chromatographic resolution, requires no any derivation for polar molecules and separates out molecules in the liquid phase. HPLC has the advantage of much wide range of analytes measurements with a higher sensitivity than gas chromatographic methods.
