New Raman Analyzer Offers Good Resolution, Great Stability

R-3000 System Provides Real-time Qualitative and Quantitative Spectral Analysis

Dunedin, Fla., April 2005 - Now available from Ocean Optics is the Raman Systems R-3000, a fully integrated Raman analyzer for real-time qualitative and quantitative spectral analysis of aqueous solutions, powders, tablets, gels and surface media from ~200-2700 cm-1.

The R-3000 is a high-performance, moderately priced system for applications such as pharmaceutical monitoring and quality control, chemical and petrochemical process and quality control, drug and explosives detection, and water-quality analysis.

The R-3000 is a third-generation instrument from Raman Systems, Inc., with notable performance gains in laser resolution (better than 10 cm-1, compared with 15 cm-1 with the previous system) and stability (better than 1 cm-1 wavelength stability and 4% output stability). New software features include fingerprinting and quantification capabilities (matching spectra to those stored in a database and determining the concentrations of constituents from models/cal-sets), and a multiple-spectrum display function (overlays of up to 20 spectra are possible). Laser power control (125 mW and 250 mW levels are available) and a high-speed USB interface offer additional convenience.

The Raman Systems R-3000 comes with a choice of 785 nm or 532 nm solid-state diode laser, a fiber optic probe with accessory "caps" for calibration and focusing, a software-controlled laser shutter, a sample holder, software and safety goggles. The probe caps are accessories that provide easy transferability between samples (solids, tablets, powders and the like) in transparent containers and in immersion applications. There are two focusing caps: one focuses the laser beam on the samples as the cap is pressed against the sample; the other focuses the laser on the inside of containers
when the cap is pressed against the outside wall. Additionally, there are caps for immersion measurements and for calibration; the latter is a pre-loaded spectroscopic standard that allows for quick, software-controlled instrument calibration and verification.
