Method and system for viewing chromatographic peaks over a network
First Claim
1. A method for displaying image files of a chromatogram on a computer-implemented screen display, the method comprising the steps of:
- (a) having a user select the chromatogram, the chromatogram having a datafile containing analytical data with optional text files including multiple display parameters;
(b) using the analytical data in the datafile in generating a metafile of the chromatogram on a server;
(c) converting the metafile to a first image file;
(d) sending the first image file to the screen display;
(e) having the user define an area of the chromatogram;
(f) using the analytical data in the datafile in generating a replacement metafile containing only the defined area of the chromatogram;
(g) converting the replacement metafile to a second image file;
(h) sending the second image file to the screen display and instantaneously replacing the first image file.

Abstract
A method and system of publishing datafile and metafile images over a network connection. A user can use a web page to transmit the name of a datafile to the server hosting the peak viewing program. The server then processes the information, launches Chromview to generate the metafiles, then uses a series of HTML pages to display the information in a .PNG image file of the datafile on the user'"'"'s computer screen. This page would have the datafile image, as well as information about the datafile (as applicable), such as the list of available ions, and start/stop times. The user could select an ion, or a start/stop time, and the resulting picture for the datafile would be displayed on his screen. The user can enlarge chosen areas of chromatograms and fragmentograms by entering values in text boxes or by clicking on two opposite corners of the selected area. The user can use either remote (Internet) or local (intranet) means to access the datafiles.

9. A method for displaying image files of a GC-MS fragmentogram on a computer implemented screen display, the method comprising the steps of:
-
(a) having a user select the fragmentogram, the fragmentogram having a datafile containing analytical data with optional text files including multiple display parameters; (b) opening the datafile for the fragmentogram and displaying a list of ion numbers of the fragmentogram; (c) having the user select an ion from the list of ion numbers; (d) using the analytical data in the datafile in generating a metafile of the ion'"'"'s fragmentogram on a server; (e) converting the metafile to a first image file; (f) sending the first image tile to the screen display. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 19)
