SEED3000 Raman Detection System

Product Introduction

The SEED3000 Raman Detection System is an integrated Raman spectroscopy analysis solution designed for routine testing, rapid screening, and material identification. Developed for non-professional users, it combines a compact instrument, professional Raman probe, and Uspectral-Ram Analysis Software for convenient operation across a wide range of applications.

Using 785 nm laser excitation, the SEED3000 provides rapid, non-destructive qualitative and quantitative analysis with minimal sample preparation. It can analyze small sample quantities as well as aqueous samples, solutions, and suspensions, helping preserve sample integrity while collecting valuable spectral information.

With its compact design and flexible probe configuration, the SEED3000 Raman analyzer is suitable for laboratory analysis and on-site material screening in food safety, pharmaceutical testing, jewelry appraisal, security inspection, and other material analysis applications.

•  Compact Integrated Design: Measures 220 × 143.1 × 58.6 mm and weighs 3.5 kg for convenient deployment.

Working Principle

The SEED3000 Raman Detection System uses Raman spectroscopy to characterize materials through the interaction between laser light and molecular vibrations. When the 785 nm laser illuminates a sample, a small proportion of the scattered light undergoes an energy shift associated with molecular vibrational and rotational states.

The instrument measures the Raman shift over a spectral range of 200–3200 cm⁻¹ to generate a characteristic spectrum. The accompanying analysis software can compare spectral features with reference data to support substance identification and, with suitable calibration, quantitative analysis.

Because the Raman shift is characteristic of molecular structure rather than the incident laser wavelength itself, Raman spectroscopy is useful for distinguishing materials and analyzing a broad range of sample types.

SEED3000 vs. Conventional Material Analysis Methods

Note: Actual performance depends on the sample, measurement conditions, spectral library, accessories, and validated analytical method. Raman spectroscopy does not identify every substance under all conditions.
