Overview

High-Resolution Mass Spectrometry (HRMS) is an advanced analytical technology that determines the exact mass of ions with high accuracy, enabling definitive determination of molecular formulas and identification of chemical compounds in a sample. HRMS differs from low-resolution technology in that it uses Orbitrap, Time-of-Flight (TOF), and Fourier Transform Ion Cyclotron Resonance (FT-ICR) technologies to achieve high accuracy at the sub-ppm level, which is essential for trace-level analysis, identification of unknown compounds, and structural determination.

HRMS technology plays a crucial role in the development of various industries, including pharmaceuticals, petrochemicals, polymers, food safety, environmental monitoring, and materials science, as it allows for advancements in formulation development, regulatory support, investigation of contaminants, and quality control, where low-resolution technology is limited in resolving co-eluting compounds and identifying unknown compounds.

Scope, Applications, and Benefits

Scope

HRMS covers exact mass measurement and structural identification of organic and inorganic compounds across a wide range of industrial matrices, supporting both targeted quantification and untargeted screening workflows.

Exact mass measurement with mass accuracy typically better than 5 ppm
Molecular formula determination and isotope pattern confirmation
Targeted and untargeted screening for known and unknown compounds
Applicable to pharmaceuticals, petrochemicals, polymers, food, environment, and materials
Supports structural elucidation via MS/MS fragmentation and database matching
Covers trace-level detection down to ng/L or pg/g depending on matrix and technique

Applications

Petrochemical and polymer additive identification
Environmental contaminant screening in water, soil, and air
Food adulteration detection and safety testing
Metabolomics and proteomics in industrial biotechnology
Forensic and failure analysis for unknown compound identification

Benefits

Sub-ppm mass accuracy enables confident molecular formula assignment
Single run covers both targeted and untargeted analysis
Resolves co-eluting isobaric compounds that low-resolution instruments cannot distinguish

Frequently Asked Questions

HRMS is an advanced analytical technique in which molecules in a sample can be precisely identified and quantified by measuring mass accurately. It detects even the smallest mass variations between molecules, thereby enabling the analysis of complex materials in great detail.

HRMS is widely used in material science to analyze polymers, nanomaterials, alloys, and composite materials. It helps identify trace elements, contaminants, and molecular structures influencing material performance, durability, and safety.

HRMS provides insight into the material composition and purity, essential in developing higher-quality, more reliable materials. By identifying contaminants and unknown compounds, such materials ensure performance and safety standards, opening a pathway to innovation.

The HRMS can differentiate between isotopes based on their mass-to-charge ratio (m/z). It could be utilized to accurately determine the isotopic distributions and ratios that could help trace material origin or forensic analysis.

HRMS examines complex samples, such as alloys and composites, where sensitivity and resolution are high. Thus, the technique best detects trace constituents and impurities in complex mixtures.
