New Spectrometry Standard for Handheld Chemical Detectors Aids First Responders

Christopher Neary of the NIST Environmental Management Group demonstrates the use of a handheld Raman spectrometer to determine the identity of an unknown sample.

When it comes to detectors for dangerous chemicals, toxins or nefarious germs, smaller and faster is better. But size and speed must still allow for accuracy, especially when measurements by different instruments must give the same result.

The recent publication of a new standard—a culmination of years of research at the National Institute of Standards and Technology (NIST)—provides confidence that results from handheld chemical detectors can be compared, apples-to-apples.

Such detectors are used by emergency responders to check for the presence of explosives or toxic chemicals that threaten public safety. Quality control managers in the pharmaceutical industry use them to verify the identity of chemicals going into their production lines.
