1ST Detect has developed a technology to allow verification of any positive results. SMARTTM (Sinusoidal Multiplexed Array in Real Time) allows a single mass peak within a spectrum to be isolated. This process is followed by fragmentation of the molecular component that produces that mass peak. This secondary fragmentation, termed MS/MS, serves as additional verification of the compound identified, as this process produces a secondary spectrum that is truly unique to each compound.
Used mainly for identification certainty and unknown identification, SMART MS/MS both improves the probability of detection through secondary verification, and reduces the percent false alarm rate by eliminating interferent compounds that may share mass peaks with target compounds.
