The QTRam portable transmission Raman spectrometer is ideal for rapid and non-destructive quantitative analysis of solid samples. In this transmission Raman system, scattered light penetrates through solid samples, allowing for measurement of the active pharmaceutical ingredients for content uniformity testing of finished products such as tablets and capsules.

  • USP-recognized transmission Raman for content uniformity testing
  • High-sensitivity and high-throughput STRaman technology allows for reliable results by transmission Raman spectroscopy
  • Intuitive workflow makes quantitative modeling and method development easy to follow
  • No sample preparation, no consumables, and no disposal costs for fast and cost-effective analyses
  • Portability for easy at-line testing for convenient QC as tablets are produced
  • Customizable sample holders for optimal sampling of your tablets

Compact design for convenient at-line testing

The portable QTRam can be used for at-line quantitation of tablet composition and other properties, reducing the time and associated production delays that come when samples need to be sent to the laboratory for in-process and final product testing.

The portable form factor of the QTRam makes it easy to use for at-line analysis and to move it anywhere you need it.

Multicomponent analysis from a single sample

The Raman spectrum is measured on the intact sample and contains information of multiple ingredients. Quantitative sample composition, crystallinity, and polymorphic form can be obtained from a single measurement.

Calibrations can be developed for multicomponent testing from a single Raman spectrum. This non-destructive analysis is done in seconds, on the tablets as they are.

Intuitive, touch-screen software operation

The QTRam can be operated using the touch-friendly BWAnalyst software. This 21 CFR Part 11-compliant software follows a logical workflow to give the quantitative content uniformity results on the inbuilt tablet computer.
