Process Monitoring – Process Guardian Raman Spectrometer

The Process Guardian is a new Raman analyser from Tornado. In addition to superior measurement performance, this next generation HTVS enabled analyser embodies all critical requirements for straightforward deployment into a process environment. Uncompromised measurements you can trust are now available from a ruggedised standalone platform.

  • Innovative – unique fibre optic cabling for reliable connection and built-in break detection
  • Intuitive – out of the box operation with simple navigation through user interface via fast action buttons and rotary dial entry
  • Reliable – allows the user to focus on their process and not worry about the accuracy or functionality of their analyser
  • Compliant – supports 21CFR Part 11 and GLP/GMP compliance
  • Compact – needing only 25×18 inches of bench space, and weighing less than 35 lbs. The Process Guardian is a versatile spectrometer for lab, field, and process solutions

Superior Analytical Performance

The Process Guardian’s analytical performance is turbocharged by Tornado’s patented High Throughput Virtual Slit (HTVS™) technology. With enhanced photon collection power, higher SNR can be achieved leading to lower limits of detection without compromising spectral resolution. High precision on both the X and Y axes makes even the toughest chemometric modelling tasks achievable.

The high-quality data delivered by the Process Guardian can provide process information related to qualitative or quantitative chemical characterisation with unsurpassed detection limits and specificity. This technological advantage delivers enhanced process understanding, which in turn leads to improved and optimised process control.

The Process Guardian offers numerous benefits for established analytical practice and facilitates broader adoption of Raman methods for pharmaceutical, petrochemical, food, biotech, and other applications.
