1ST Detect has developed a revolutionary chemical detector based on a linear ion trap (LIT) mass spectrometer. Our proprietary ion trap leverages technology from the space program, allowing the device’s portability, versatility, sensitivity, durability, high speed and low cost.
In a linear ion trap mass spectrometer, ions are contained within a defined location (the ‘trap’) by the use of RF electric fields. Ions are then sequentially ejected by adjusting this field in a controlled manner and a mass spectrum is generated by measuring these ejected ions with a detector. The resulting mass spectrum provides a unique identifier or ‘fingerprint’ that allows the 1ST Detect ion trap to unambiguously detect and identify a wide variety of chemicals.
