41. In this case, the matrix may interfere with or attenuate the signal of the analyte . 42. The area under a peak is proportional to the amount of analyte present in the chromatogram. 43. Consider a solution containing the analyte , A, in the presence of some conductive buffer. 44. Ionization of sample ( analyte ) is achieved by interaction of its molecules with reagent ions. 45. This causes an electron to be released from the analyte molecule, producing a Ne ). 46. To determine the quantity of analyte in a sample, an substrate for the enzyme reaction. 47. Inside the ion source, the reagent gas is present in large excess compared to the analyte . 48. Experimentally, the electroosmotic mobility can be determined by measuring the retention time of a neutral analyte . 49. The velocity ( u ) of an analyte in an electric field can then be defined as: 50. Through a microflow system, a solution with the prey analyte is injected over the bait layer.
