INdepth drug test

After reading a sample, data from the cartridge is collected and shown on the computer. By looking at the mass and charge of the molecule, it will show what drug is in the system. The cartridge, about the size of a fingertip, separates the drug from the droplet of blood so it can be identified with a mass spectrometer, an instrument used to identify the kinds of particles present in a given substance.
