PTRam Process Development Raman Analyzer

Importance of Raman Process Monitoring

Real-time spectroscopic analysis provides critical insight into chemical transformations and material properties during manufacturing. Implementing Raman-based process analytical technology (PAT) enhances product quality, reduces development time, and supports regulatory compliance in pharmaceutical, petrochemical, and chemical industries.

Study Objective and Overview

The PTRam™ Raman Analyzer is engineered as a 19″ rack-mount system to support product and process development. This whitepaper outlines its core design, operational strategies, and targeted applications, demonstrating how a robust Raman platform delivers continuous monitoring and automated validation for diverse industrial workflows.

Methodology and Instrumentation

The analyzer employs a high-resolution spectrometer paired with a stabilized 785 nm laser source. Key design elements include:

• Fiber-optic coupling to a single-channel sampling probe for remote and inline measurements
• Automated calibration routines and self-monitoring algorithms to verify spectral accuracy
• 24/7 real-time data acquisition and system validation to ensure uninterrupted performance

Used Instrumentation

Standard configuration includes:

• Lab-grade BAC100B-785-HT fiber-optic probe, 1.5 m length
• Laser safety goggles for operator protection
• ASTM polystyrene validation standard (NR-PCC)
• Vision® software (Windows-based, non-pharma version) for data acquisition and analysis

Main Performance and Discussion

The PTRam demonstrates:

• High spectral resolution and sensitivity to detect active pharmaceutical ingredients, polymers, and bioprocess markers
• Long-term laser output stability for consistent spectral quality over extended campaigns
• Automated system checks that reduce manual intervention and downtime

These attributes support accurate monitoring of reaction chemistry, crystallization transitions, and formulation processes.
