  1. NeSSI Compatible Spectroscopic Flow Cells Mike DoyleAxiom Analytical, Inc.

  2. Unique Requirements of Spectroscopic Process Analysis • Use of broad spectrum optical radiation • Need to couple to complex remote instruments • Need to produce SPC plots from large arrays of data

  3. Comparison Of Four Forms Of Process Molecular Spectroscopy

  4. Applicability of Various Sampling Methods

  5. Spectroscopic Methods Appropriate to the NeSSI Platform Samples Type – Clear liquids Methods: • Near-IR: Transmission • UV-Visible: Transmission and ATR • Raman: Backscatter • Mid-IR: ATR ?

  6. The NeSSI Platform Objectives • Standardize and simplify systems for process analysis • Provide a system of miniature, interchangeable sample handling components • Analyzer systems close to the sampling point • Short lines, fast response • Modular assembly

  7. Axiom Product Overview – Fluid AnalysisNear-IR and UV-Visible Transmission Established Products • FPT-850 Transmission Probes • FCT Series Cross-Line Sampling Systems • FFV-300 Series Transmission Cells • FST-500 Unistage Transmission Sampler Most Significant Development • Permanent Welded-in Metal Seals Recent Developments • Self Cleaning Probes • Small Diameter Probes • Polymer Melt Transmission Probes • NeSSI Compatible FFV Transmission Cells
