Dual Point Sampling: HORIBA PI-200-DP Process Raman Analyzer
When two sampling points are required but deploying two separate analyzers is not operationally practical, the PI-200-DP provides a direct solution. HORIBA's PI-200-DP Dual Point On-line Process Raman Analyzer monitors two distinct sampling points from a single system, delivering real-time chemical analysis without doubling analyzer complexity.
Whether the application calls for measuring the start and finish of a chemical reaction, comparing feed against product quality, or monitoring two independent process streams, the PI-200-DP integrates with HORIBA's sampling enclosures or pre-existing sampling setups without requiring a complete system overhaul.
Your Simple, Cost-efficient Turnkey Solution
At HORIBA Process Instruments, we understand the unique demands of your industry. Our cutting-edge dual-point Raman analyzer solutions are designed to deliver accurate, real-time insights for process optimization, safety, and compliance. From oil and gas to pharmaceuticals and beyond, we provide reliable tools that empower you to monitor critical parameters, reduce operational costs, and improve product quality.
When Dual-Point Monitoring Is the Right Fit
The PI-200-DP addresses applications where a single measurement point is insufficient, but the complexity and cost of a full multichannel system are not warranted. It is most commonly deployed in the following scenarios:
- Reaction monitoring: Measuring at both the inlet and outlet of a process unit, such as a reformer or hydrotreater, to track conversion and yield in real time.
-
Feed vs. product comparison: Analyzing a raw feed stream alongside its processed output to confirm quality targets are met before the product moves downstream.
-
Two independent streams monitoring: Replacing two separate analyzers with a single system to reduce hardware complexity, footprint, and ongoing maintenance costs.
- Sequential control point monitoring: Tracking a process at two critical stages, such as monitoring two gasoline streams of different octane quality.
For facilities with a clearly defined two-point monitoring requirement, the PI-200-DP delivers the precision of a full Process Raman system in a configuration matched to the application.

Applications
The PI-200-DP is suited for a broad range of refinery and petrochemical process monitoring applications. Priority applications include:
Gasoline Blending
Monitor neat and reformulated gasoline composition, blending components, and critical fuel parameters such as octane rating in real time across two points in the blending process.
Crude Distillation
Track LPG composition, straight run naphtha characterization, and distillate stream quality across two monitoring points in crude unit operations.
Cracking
Support FCC unit monitoring for olefins and cracked naphtha, hydrocracker and coker distillate and naphtha streams, and ECC unit light naphtha, propylene, and ethylene tracking.
Reforming
Compare feed and product streams simultaneously, monitor benzene reduction progress, and track aromatics production in real time.
Additional Applications
-
Diesel and jet fuel blending
-
Naphtha processing
-
Alkylation: olefins, butane, and C2/C3 fractionation
-
Vacuum tower: lube oils, heavy gas oil, hydrowax
-
