What is High-Resolution Mass Spectrometry (HRMS)?
High-Resolution Mass Spectrometry (HRMS) is a modern technology designed to measure molecular masses with extraordinary accuracy. Unlike low-resolution systems, HRMS can tell apart molecules that differ by even a fraction of a Dalton. This ability is extremely important in pharmaceutical, clinical, food, and environmental studies. Small differences in molecules can impact drug safety, food quality, or environmental assessments, and HRMS helps detect them with confidence.
At ResolveMass Laboratories Inc., we focus on HRMS applications such as impurity profiling, biomarker testing, and nitrosamine analysis. These services ensure regulatory compliance while also supporting innovation in healthcare, biotech, and life sciences.
How Does HRMS Work?
HRMS works by ionizing a sample, sorting the ions by their exact mass-to-charge ratio (m/z), and then detecting them with high precision. Because of this resolving power, the system can separate molecules that would otherwise appear identical in low-resolution testing.
- Ionization → Techniques like electrospray ionization (ESI) or MALDI generate ions.
- Separation → Tools such as time-of-flight (TOF), Orbitrap, or quadrupole analyzers sort the ions.
- Detection → Specialized detectors capture exact m/z values with impressive accuracy.
Understanding this process is vital for applying HRMS effectively. ResolveMass provides expert consultation and resources to help clients develop workflows tailored to their research or industry needs.

FAQs About High-Resolution Mass Spectrometry (HRMS)
Analyzing HRMS data involves processing raw spectra to identify the exact mass-to-charge ratio of ions. Specialized software tools help assign molecular formulas, compare results with databases, and detect impurities or biomarkers. At ResolveMass, our experts ensure that complex HRMS data is transformed into clear, validated results that support research and regulatory needs.
HRMS is important because it allows scientists to measure molecular masses with a level of detail not possible in standard techniques. This precision is critical in drug discovery, food safety, and environmental monitoring, where even the smallest molecular differences can affect results. It has become an essential tool for modern analytical science.
The main advantages of HRMS include extremely high accuracy, the ability to detect unknown compounds, and sensitivity down to trace levels. It also offers reproducible results and a wide dynamic range for quantification. These benefits make HRMS valuable in industries where data reliability directly impacts safety, compliance, and innovation.
The range of HRMS generally depends on the instrument used, but most systems can measure ions across a wide mass-to-charge (m/z) spectrum. This broad range allows researchers to study small molecules like metabolites as well as larger biomolecules such as peptides and proteins. The flexibility of range is one reason HRMS is so versatile.
Standard mass spectrometry provides mass measurements but may group together molecules with similar nominal masses. High-resolution mass spectrometry, on the other hand, separates these molecules with extreme precision, often down to less than 0.001 Da. This makes HRMS much more powerful for complex mixtures and regulated testing environments.
The sample concentration needed for HRMS depends on the type of analysis and instrument sensitivity. In many cases, only nanogram to microgram levels of material are required, since HRMS can detect analytes at very low concentrations. This makes it suitable for studies where only limited sample amounts are available.
The cost of HRMS can be high, as advanced instruments and their upkeep are expensive. For many researchers and companies, outsourcing HRMS to specialized laboratories like ResolveMass is a cost-effective solution. This way, clients gain access to advanced instruments, validated methods, and expert guidance without the heavy investment of owning the technology.
HRMS can analyze a wide range of sample types, including pharmaceuticals, proteins, lipids, peptides, metabolites, and polymers. It is also valuable for detecting contaminants such as PFAS in environmental testing, making it a versatile tool across both research and regulated industries.
Yes, one of the biggest advantages of HRMS is its ability to predict accurate molecular formulas for unknown compounds. This makes it especially useful in drug discovery, metabolomics, and environmental testing, where identifying unexpected substances is often critical.
