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.
Food Safety Testing
The Portman 785 is well-suited for food quality control and compositional analysis, covering applications such as process monitoring, qualitative and quantitative evaluation of ingredients, and food safety inspections.
Water Environment Monitoring
The Portman 785 utilizes surface-enhanced Raman spectroscopy (SERS) for rapid and highly sensitive detection of waterborne contaminants, including heavy metal ions, organic compounds, and microplastics. It delivers precise trace-level analysis to support water protection initiatives and effective pollution control.
Jewelry and Antiquities Sector
The Portman 785 enables accurate gemstone authentication, compositional analysis, and material identification of historical artifacts. It provides precise analysis of inorganic cultural relics—such as pigments, metals, and ceramics—as well as organic materials like dyes and adhesives, offering essential insights for artifact preservation and restoration.
