TruScan RM Handheld Raman Analyzer for Pharmaceutical Material Identity Verification FAQs
A: Pharmaceutical manufacturers use TruScan RM for raw material analysis in the manufacturing of pharmaceutical products. A non-expert operator can use a handheld TruScan RM to accurately verify materials quickly. The efficient use of TruScan RM streamlines material verification and makes 100% material inspection cost-effective while maintaining high quality standards.
TruScan RM QA/QC applications include enhanced raw material ID for similar compounds, multiple component ID, and identification and quantification of intermediate and finished products. In PAT, applications include at-line endpoint determination for distillations, reaction monitoring, and powder blending operations.
In addition, the TruScan RM analyzer is used by pharmaceutical manufacturers to identify counterfeits in order to protect patients and brand integrity.
A: Falsified or substandard medicines are a growing problem worldwide. To protect patients and brand integrity, pharmaceutical manufacturers use TruScan RM to identify counterfeits. The TruScan RM allows users without chemistry training to conduct field-based screening of pharmaceutical samples and quickly and accurately identify falsified or substandard medicines. Because the spectrum generated by the TruScan RM examines all the components of a pharmaceutical dosage form: API, excipients, fillers, dyes, coatings, etc. to generate a spectrum representative of all components (and their relative concentrations) any slight deviation from the original formulation will lead to a detectable change in the resulting spectrum, providing detection of counterfeit pharmaceuticals in the field.
A. TruScan RM can save manufacturing resources. Each year plant personnel spend hours moving materials into the sampling room, sampling them, documenting samples for tracking purposes and sending them to the lab, then moving materials into a quarantine area to await laboratory results. With TruScan RM handheld Raman analyzer, incoming materials may be verified in the warehouse, by-passing all the traditional central laboratory testing steps – saving time and manufacturing resources such as personnel, plant space, and inventory costs.
QC laboratory testing is also resource intensive. Highly qualified lab personnel spend numerous hours preparing and analyzing samples, reviewing data, and documenting procedures and results. Identity testing occupies valuable instrument time that could be used for other analyses. Consumables like sample vials and reagents along with chemical disposal fees add to laboratory costs. Using non-destructive, no-contact Raman handheld analyzers like TruScan RM, pharmaceutical manufacturers avoid all these costs.
Traditional sampling and laboratory testing introduces production risks that have the potential to impact product quality, yield, and production schedule. Opening a container to extract a sample increases its chance of material contamination and rejection of the final product. Sampling and lab analysis adds variability to material release times. Samples may be accidentally contaminated, destroyed, lost, or mislabeled in a traditional central laboratory testing workflow. The variabilities of turnaround time for material inspection may impair the ability to forecast production equipment and personnel scheduling – a direct stress on plant productivity. Non-contact, non-destructive TruScan RM analysis reduces contamination risks and production uncertainties.
A: TruScan RM is a handheld Raman analyzer. In Raman spectroscopy, an unknown sample of material is illuminated with monochromatic (single wavelength or single frequency) laser light, which can be absorbed, transmitted, reflected, or scattered by the sample. Light scattered from the sample is due to either elastic collisions of the light with the sample’s molecules (Rayleigh scatter) or inelastic collisions (Raman scatter). Whereas Rayleigh scattered light has the same frequency (wavelength) of the incident laser light, Raman scattered light returns from the sample at different frequencies corresponding to the vibrational frequencies of the bonds of the molecules in the sample.

The TruScan RM analyzer is built with a state-of-the-art optical platform paired with a field-proven embedded chemometrics engine. The patented, multivariate residual analysis offers the most effective chemometric solution for material identification – with two spectral pre-processing options (1st and 2nd derivative), that is easy to operate in challenging environments and sampling conditions.
In addition to Raman technology, the TruScan RM has TruTools, an optional embedded chemometrics software package, with which users can build advanced, customized qualitative and quantitative methods for complex material analysis problems. TruTools models allow discrimination of multiple components, discrimination of raw materials with minimal spectral differences (such as Ethanol and methylated spirits), and discrimination of low API dosage tablets from placebos. With TruTools deployed on a TruScan RM, non-expert operators can run advanced chemometric analyses anywhere in the plant.

A: cGMP requires instituting strong quality management systems, obtaining appropriate quality raw materials, establishing proper operating procedures, detecting and investigating any product quality issues, and maintaining reliable testing laboratories.
PIC/S, Annex 8 PIC/S, Annex 8 requires that individual samples be taken from all incoming containers – 100% material inspection – rather than the traditional practice of composite sampling of a statistical subset of the batch, and an identity test be performed on each sample.
The TruScan RM meets cGMP requirements and the rigorous sampling demands of PIC/S Annex 8. TruScan RM allows non-expert users to identify and quantify raw materials, intermediates, and finished products on site in seconds. Replacing time-consuming, expensive laboratory sampling with handheld Raman analyzers’ rapid verification of chemical compounds makes possible efficient and regulatory compliant 100% material inspection.

Spectroscopic material verification is a critically important analytical application within the pharmaceutical industry. Analytical devices employed in the pharmaceutical environment require performance characterization. In applications for material verification and identification, strict rules must be defined for robust, repeatable operation of these devices by non-expert users. Traditional analytical methods of measuring qualitative performance are unsuitable for characterizing identification of unknowns.
