The Portman Series portable Raman spectrometer is a compact Raman system designed for both laboratory use and on-site detection across a wide range of applications. The main unit can be configured with different excitation wavelengths, spectral ranges, and resolutions based on specific customer needs and application scenarios. Equipped with a laser that meets Class IIIB safety standards, the system supports full software control and enables one-click data acquisition for a streamlined user experience.
A variety of sampling accessories are available to accommodate solids, liquids, powders, and other sample forms. Specialized attachments such as micro-area sampling modules and immersion probes make the Portman Raman system suitable for complex scenarios including SERS, 2D materials, gemstones, online chemical analysis, biopharmaceuticals, and pharmaceutical applications.
The software includes advanced features such as fluorescence removal, signal extraction, material identification, and spectral database management. The Portman Raman spectrometer has been widely adopted in industries such as food safety, homeland security, gem identification, and pharmaceuticals for rapid raw material screening, on-site detection, and substance identification.
Graphene Characterization
The Portman 532 enables reliable determination of graphene layer numbers, structural and property characterization, defect analysis, stress measurement, and electron–phonon interaction studies. It serves as a powerful tool across materials science, micro/nano fabrication, energy, biomedical research, and drug delivery applications.
Environmental Applications
The Portman 532 performs both qualitative and quantitative analysis of gas compositions, making it highly effective for mixed-gas detection. It excels in monitoring toxic and corrosive gases and can distinguish isotopic molecular species and their relative concentrations.
