In the mass spectrometer of the present invention, a flight space is provided before the mass analyzer, and the flight space includes a loop orbit on which ions fly repeatedly. While ions fly on the loop orbit repeatedly, ion selecting electrodes placed on the loop orbit selects object ions having a specific mass to charge ratio in such a manner that, for a limited time period when the object ions are flying through the ion selecting electrodes, an appropriate voltage is applied to the ion selecting electrodes to make them continue to fly on the loop orbit, but otherwise to make or let other ions deflect from the loop orbit. If ions having various mass to charge ratios are introduced in the loop orbit almost at the same time, the object ions having the same mass to charge ratio continue to fly on the loop orbit in a band, but ions having mass to charge ratios different from that are separated from the object ions while flying on the loop orbit repeatedly. Even if the difference in the mass to charge ratio is small, the separation becomes large when the number of turns of the flight becomes large. After such a separation is adequately achieved, the ion selecting electrodes can select the object ions with high selectivity, or at high mass resolution. By adding dissociating means, fragment ions originated only from the selected object ions can be analyzed, which enables the identification and structural analysis of the sample at high accuracy.

The invention provides methods for the detection, quantification, identification and structural analysis of one or more molecules. Mass spectrometry (MS) is not a universal detector as all molecules do not ionize equally well leading to poor signal to quantity information. MS can be optimized to identify the specific mass of a binding component when the presence of a material is known. Colorimetric resonant reflectance optical sensors provide a universal mass detector in that nearly all biological masses give equally proportional signals. The combined methods allow selection and or detection with quantification of all masses binding to the sensor with the ability to identify specific molecules by their individual masses and structure analyses.
