The SM-3500 provides field, portable measurement and
analysis across the full UV/VIS/NIR spectral range from
350-2500nm. It provides the technology to screen and
authenticate drugs without removing them from their
Counterfeit drugs are a worldwide problem - detrimental in three
major ways:
  • Patients don't receive the correct drug, leading to injury
    and/or death
  • Patients receive contaminated versions of the correct
    drug, which may be toxic
  • Pharmaceutical companies lose billions of dollars in
Visual inspection, especially of drug packaging,and traceability
through package identification such as bar codes, are the most
common ways of dealing with potential counterfeiting. However,
counterfeit packaging is often very close to the original, even
down to the identification codes. With an NIR spectrometer, such
as the
SM-3500, it's possible to identify the authenticity of a drug
even in its packaging, including bottles and blisterpacks.   

An NIR spectrometer can help combat counterfeit drugs by
allowing identification and authentication using spectral
matching by:
  • Taking sample spectra of authentic drugs to form a known
  • Checking target drugs against those spectra for

The portability of a NIR spectrometer like the SM-3500 makes it
well-suited to this type of application, since identification can be
performed in the field at:
  • Manufacturing facilities
  • Warehouses
  • Hospitals
  • Pharmacies
  • Government agency field operations

Counterfeit drug applications can include:
  • Identification of samples with minimal or no preparation
  • Rapid analysis, as quickly as 1 second per tablet
  • Non-destructive - perform analysis with the drug still in its
  • Gain information on structural and chemical characteristics
  • Spectral match authenticates drugs
  • Portability for field use anywhere
  • Screen for antimalarial drugs in developing countries
  • Identify criminal and substandard counterfeits
  • Apply to a wide range of drug types, including antibiotics,
    hormones, steroids, analgesics, and more
  • Chemometric analysis of samples provides in-depth
    information, including API (active ingredients)
  • Also analyze for excipients (non-active ingredients)
  • Usable with physical/chemical identifiers/markers in
    genuine drugs
  • Potential use as a field tool by non-scientific personnel
