Hydrogen Forward Scattering Spectrometry (HFS) Testing for H Depth Profiling
Hydrogen Forward Scattering Spectrometry (HFS) uses forward recoil detection of Hydrogen nuclei, due to impinging Helium ions, to quantify Hydrogen atoms in thin films and near surface layers of solids. The Infinita Lab network of testing labs, USA offers the HFS test to our clients in the USA and other places.

Overview
Hydrogen Forward Scattering Spectrometry (HFS) is an advanced, specialized ion-beam analysis technique used for quantitative depth profiling of hydrogen concentration in thin films, coatings, and surface layers of solid materials. With hydrogen content analysis and depth profiling, the HFS technique provides accurate, non-destructive measurement and analysis of hydrogen content in thin films and coatings, helping materials engineers, thin-film experts, and researchers achieve critical hydrogen-content quantification intelligence for material and thin-film characterization and analysis programs.
Scope, Applications, and Benefits
Scope
A high-energy ion beam is focused on the surface of the sample material by HFS, and forward-scattered hydrogen recoil atoms are detected by a particle detector at a fixed forward scattering angle. Quantitative hydrogen concentration and depth-profile analysis of surface and surface-layer materials is thus made possible without sample damage or complex sample preparation.
HFS analysis evaluates:
- Quantitative hydrogen concentration measurement in thin films, coatings, and surface layers
- Hydrogen depth profile distribution across defined near-surface material regions
- Hydrogen incorporation in diamond-like carbon, nitride, oxide, and semiconductor thin film systems
- Surface and bulk hydrogen content in metals, ceramics, and advanced material systems
- Hydrogen concentration compliance against the defined material specification requirements
Applications
- Diamond-like carbon (DLC) and hard coating thin films require hydrogen content characterization
- Semiconductor and electronic device materials with hydrogen-sensitive performance properties
- Nitride, oxide, and carbide thin film coatings requiring hydrogen incorporation analysis
- Hydrogen storage and energy materials requiring quantitative bulk hydrogen measurement
- Advanced materials research programs requiring non-destructive hydrogen depth profiling
Benefits
- Provides quantitative hydrogen concentration and depth profile data unavailable through conventional analysis techniques
- Delivers non-destructive hydrogen measurement without requiring specimen sectioning or dissolution
- Supports thin film development, coating characterization, and material qualification programs
- Delivers traceable, laboratory-certified hydrogen quantification data
- Reduces material development risk by providing accurate hydrogen content data early in the characterization cycle

Frequently Asked Questions
HFS is a specialized ion beam analysis technique for quantitative measurement of hydrogen concentration and depth distribution in thin films, coatings, and surface layers, using forward-scattered hydrogen recoil atoms produced by high-energy irradiation of the specimen surface.
These include thin films, hard coatings, DLC films, semiconductor materials, nitride and oxide coatings, metals, and ceramics, and it offers quantitative hydrogen content and depth-profile information across a broad range of solid material systems where hydrogen content is significant.
This is because HFS offers non-destructive quantitative depth profiling of hydrogen without specimen dissolution and sectioning, which provides concentration-depth data within near-surface material layers and has unique advantages over combustion analysis, SIMS, and conventional methods of bulk hydrogen determination.
