Embodiment Construction

[0043] Computer implementation system

[0044] figure 1 It is a block diagram illustrating a computer system 100 of an embodiment of the present teach. Computer system 100 includes a bus 102 or other communication mechanism for transmitting information, and a processor 104 coupled to bus 102 for processing information. Computer system 100 also includes a memory 106 coupled to bus 102, which may be a random access memory (RAM) or other dynamic storage device for storing instructions to be performed by processor 104. Memory 106 can also be used to store temporary variables or other intermediate information during execution of instructions to be performed by processor 104. Computer system 100 also includes a read-only memory (ROM) 108 or other static storage device coupled to bus 102 for storing static information and instructions for processor 104. A storage device 110 such as a disk or a disc is provided and coupled to the bus 102 to store information and instructions.

Abstract

A separation device is instructed to separate a compound from a sample over a time period. A mass spectrometer is instructed to measure a plurality of intensities of at least one ion of the separated compound over the time period, producing a chromatogram. At least one peak of the at least one ion is identified from the chromatogram using a peak-finding algorithm. Two or more different peak integration areas are calculated for the at least one peak by applying the peak-finding algorithm with two or more different values for at least one peak-finding parameter. Two or more plots of the at least one peak that each shows graphically a different peak integration area are displayed on a display device at the same time. In response, data is received from a user selection device that indicates user selection of one of the two or more plots.

Description

[0001] Related application [0002] This application claims the 2020 June 12 filed US Provisional Patent Application Serial interests No.62 / 860,310, the contents of which are incorporated herein by reference in its entirety. Background technique [0003] Teachings herein relate to apparatus and methods for the chromatographic peak integration systems, including but not limited to liquid chromatography (LC) and gas chromatography (GC). More specifically, the two simultaneously displayed to a user or more peaks integration area, and allows the user to select a preferred integration region. This method reduces the time to view and select the appropriate peak area integration takes. The method is independent of the detection system used (mass spectrometry (MS), ultraviolet (UV), etc.). [0004] Apparatus and methods disclosed herein may be a processor, controller, microcontroller, or a computer system (such as figure 1 The computer system) binding executed. [0005] Mass background ...
