In the last decades, mass spectrometry has been increasingly used in pharmaceutical analysis, both for research aims and routine quality controls. Among different instrumental setups, ultra-high-resolution mass spectrometry with Fourier transform instruments, i.e., Fourier transform ion cyclotron resonance (FTICR) and Orbitrap, give access to valuable molecular information for pharmaceutical analysis. They are increasingly used for the possibility of measuring accurate mass-to-charge ratios, which can often enable a direct interpretation of the studied system without acquiring additional information, as in the case of low-resolution mass spectrometers. In addition to accurate measurement, high-resolution mass spectrometry can produce compositional and structural information on small molecules, biomolecules, and complexes.
The state government agencies and PSUs have invited 33 high-resolution mass spectrometer system tenders so far this year. Because of the possibilities for advancement in developing markets due to the greenfield initiatives being installed in numerous end-user industries in those international locations, India significantly demands single mass spectrometers and hybrid spectrometry devices.
A central facility for mass spectrometry-based proteomics, metabolomics, and lipidomics platforms was inaugurated in May 2023 at the Rajiv Gandhi Centre for Biotechnology (RGCB) in Thiruvananthapuram by Dr Vinod Kumar Paul, Member NITI Aayog.
Mass spectrometers are commonly used for PFAS (per- and polyfluoroalkyl substances) testing. Mass spectrometry is a powerful analytical technique that can detect and quantify various compounds, including PFAS, with high sensitivity and specificity. It is often employed in environmental, food safety, and forensic laboratories for the analysis of PFAS in various matrices, such as water, soil, air, and biological samples. Mass spectrometry techniques, such as liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS), are commonly used for PFAS testing due to their ability to separate and identify individual PFAS compounds in complex mixtures.
In India, the awareness on the PFAS is limited, and currently no regulations are in place in any of the products. The Indian industries need to be prepared for the challenges of PFAS as their products may face scrutiny in the global market, particularly EU, Japan, and the USA. The government is expected to implement PFAS testing regulations soon, and this will provide impetus to the market.

In analytical science, mass spectrometry (MS) has emerged as a foundation for innovation, transforming our ability to identify, quantify, and characterize the compounds with unprecedented resolution and precision. Recent advancements in MS have propelled the analytical chemistry field to new heights, revolutionizing analytical capabilities across disciplines, such as environmental science, food industry, forensics, drug discovery, biologics development, etc. One major advancement lies in the instrumentation, where improvements in resolution, sensitivity, and speed have led to the development of high-resolution mass spectrometers (HRMS). Emergence of portable MS, enabling on-site analysis in remote or non-laboratory settings and ambient ionization mass spectrometry (AIMS) methods, has transformed the analytical science, expanding the scope of MS to include real-time and in vivo analysis.
In drug development, the HRMS stands as a cornerstone technology, revolutionizing the way drugs are discovered, characterized, and manufactured. One notable advancement is the development of electron-based fragmentation methods, such as electron capture dissociation (ECD) and electron transfer dissociation (ETD). These techniques are particularly valuable for analyzing biomolecules like peptides and proteins, as they produce extensive fragmentation patterns while preserving labile post-translational modifications. Furthermore, HRMS facilitates the identification and quantification of post-translational modifications, impurities, and degradation products, imparting confidence in the integrity of biologic drugs.
A few prominent emerging trends in MS involve the single-cell analysis techniques, High-throughput screening methodologies and enhanced capability HRMS in identifying unknown compounds. Integrating the multi-omics data and artificial intelligence (AI)/machine learning (ML) algorithms is offering a holistic view of biological systems, enhancing data analysis and biomarker discovery efforts.
Considering the scientific needs of today’s research landscape, the HiMedia laboratory’s recent acquisition of Orbitrap Fusion Tribrid MS into its state-of-the-art analytical facility represents a bold commitment to pushing the boundaries of analytical capabilities and driving forward the frontiers of discovery. By collaborating with HiMedia, clients can gain access to invaluable cutting-edge HRMS technology, critical for supporting science projects by enabling precise identification, quantification of compounds, and in-depth characterization of biotherapeutics.
Mass spectrometry is a powerful tool for analyzing the proteome in cancer research. This technique can be combined with machine learning algorithms to identify proteomic signatures that act as potential biomarkers to predict survival outcomes in patients with cancer treated with immunotherapy. MS allows for a top-down approach, enabling global analysis of intact protein from blood samples. Unlike antibody-based approaches (which have the potential to introduce biases based on the specific proteins being targeted), MS looks at the proteome globally, making it an unbiased assay. Many types of MS exist, each with their own advantages for use. One type, matrix-assisted laser desorption/ionization time-of-flight (MALDI-ToF) MS uses laser energy to convert analytes into gaseous ions with minimal protein fragmentation. An ionization matrix is used to absorb the laser energy and assist in the ionization of the analytes and the conversion into the gaseous phase. Subsequently, the time required for a given analyte to pass through an electric field and be captured by a detector is measured using the ToF mass spectrometer. The mass-to-charge ratio of each detected ion is recorded and yields a spectrum representative of the specific composition and abundance of analytes.
One of the newborn screening methods to detect inherited metabolic disorders caused by congenital enzyme defects uses tandem mass spectrometry. Mass spectrometers ionize a target substance, identify the specific substances, then determine the amounts of such substances in the extremely small samples like dried blood filter paper. This has yet to gain popularity in India.
