Abstract: A first liquid sending controller of an analysis control device controls a first liquid sender such that a mobile phase is supplied to a fluorescence detector through an analysis column and a junction during an analysis of a sample. A sample introduction controller controls a sample introducer such that the sample is introduced into a mobile phase by the sample introducer at a position farther upstream than the analysis column during the analysis of the sample. The second liquid sending controller causes a second liquid sender to start supplying a fluorescent reaction liquid such that the fluorescent reaction liquid arrives at the junction later than a point in time at which supply of the mobile phase starts and before the sample introduced into the mobile phase arrives at the junction during the analysis of the sample. A generator generates a chromatogram based on an output signal of the fluorescence detector during the analysis of the sample.

During successive experiments, spectra from periodic MS scans are used to determine the correspondence between the current time and the time in the control experiment. The active set of MSn scans to be acquired by the instrument is then determined as the scans with adjusted retention time windows that bracket the corrected retention time.

Abstract: This patent deals with methods to extract and analyze seismic signals due to resonance phenomena in an enclosed oil, gas, or water reservoir, which are passively excited by seismic background noise, locating thereby the presence of the reservoir by doing qualitative and quantitative estimates via forward modeling. Measurements are first used in a qualitative analysis in eight steps. The influence of gas bubbles is important. A quantitative method in form of a numerical simulation using one of several specific physical concepts is used for further analysis. By using successive forward modeling, together with investigation and feedback and in conjunction with the Monte Carlo method, more details are gained. It is also possible to determine the fluid type. The uniqueness of the methods is first that it is purely passive; second it is directly sensitive to the oil or gas, because the resonance effect is only present for a fluid.
