1. Introduction to the HPLC ChemStation and Acquisition

2. 2 In This Section, We Will Discuss: How to work in the Microsoft Windows Environment The structure of the ChemStation Software. How to set up an acquisition method. How to run a single sample.

3. 3 l Delete temporary files on a regular basis. Use Clean Disk for Windows 2000 and XP. l Use Checkdisk to find and correct errors on the disk. l Defragment the hard drive. l Use Virus detection software. l Create an Emergency Repair disk.

9. 9 Parts of a Method l Method information l Instrument control parameters l Data analysis parameters l Run Time Checklist What is a Method? A method comprises all the parameters necessary to perform data acquisition and data analysis, including integration and calibration parameters, for one sample. Pre- and post-run tasks may be specified by a command or macro in the run-time checklist. The method is identified by a file name with a.m extension. Master methods are stored in Chem32\#\Methods.

10. 10 Instrument Parameters and Control: System Diagram or Menus Click on GUI for parameters. Instrument control via menus or GUI Click here for instrument control.

11. 11 Create a Method In the Method and Run Control view, Select New Method, or double-click on DEF_LC.M. DEF_LC.M is loaded. This method is a template file that cannot be overwritten.

12. 12 You may use Edit Entire Method to sequentially move through instrument parameters required to acquire data for one analysis or access the parameter windows by selection. Note: Edit Entire Method does not access all instrument parameters such as More Pump > Auxiliary, etc. Editing a Method Using “Edit Entire Method”
