The possession of d-methamphetamine is a criminal offense prosecutable at different levels based on amount in possession. The following compounds may or may not be present in a sample confiscated from a suspected met lab. The other compounds are starting materials, fillers, or substitutes (for the purpose of defrauding buyers). The possible compounds in the mixture include: If the compounds above were separated using capillary GC, what would be the most appropriate detector for trace analysis? (A) FTIR (B) electron...

(Figure 1) shows a mass spectrometer, an analytical instrument used to identify the various molecules in a sample by measuring their charge-to-mass ratio q/m. The sample is ionized, the positive ions are accelerated (starting from rest) through a potential difference ΔV, and they then enter a region of uniform magnetic field. The field bends the ions into circular trajectories, but after just half a circle they either strike the wall or pass through a small opening to a detector. As...

In a mass spectrometer, a singly charged ion having a particular velocity is selected by using a magnetic field of 7.0×10−2 T perpendicular to an electric field of 1.0×103 V/m . A magnetic field of this same magnitude is then used to deflect the ion, which moves in a circular path with a radius of 1.3 cm . What is the mass of the ion? Express your answer using two significant figures.
