GERSTEL Solutions Worldwide Service GERSTEL MAESTRO Software Virtuosity Defined The GERSTEL MAESTRO software provides harmonious and efficient integrated control of GERSTEL modules and solutions. MAESTRO was introduced in early 2006, replacing the established MASter software; MAESTRO provides significant improvements in flexibility and ease-ofuse, both in method generation and in the analysis sequence set-up. Ease-of-use ultimately translates to less errors, less time spent setting up analyses, and improved lab productivity. GERSTEL gratefully acknowledges our customers contributions.By providing valuable insights and suggestions they have made MAESTRO software more useful in the laboratory environment. In this article, we would like to show how MAESTRO helps to quickly and easily set up analyses, simplifying and speeding up your every day activities in LC/MS and GC/MS The author Sabine Fischer GERSTEL GmbH & Co.

GERSTEL Solutions Worldwide Service How to conduct yourself in a new software environment GERSTEL MAESTRO step-by-step To give you a clear view of the efficiency and ease-of-use of MAESTRO software operation, this article will provide a step-by-step guide on how to set up a method. Even with little or no experience from MAESTRO’s predecessor, the MASter software, you will be able to familiarize yourself with MAESTRO very quickly. Whatever the task at hand and no matter which system configuration you have: The detailed, easy-to-use MAESTRO-online help guides you all the way. Help topics are divided into chapters and sections similar to the structure of an operator’s manual. The information is easily accessed, providing answers to your questions concerning software handling in a clear and concise manner, in English, German or Japanese. Several convenient ways to find help and information: Accessing on-line help There are several easy ways to find information when you need it. You can either select the menu item Help – Help Topics – GERSTEL MAESTRO from the menu line, opening the start page of online help, or you simply click on the help button in the input window. Context-sensitive on-line help is available, just place the cursor on an input field or button and push the F1 key. In this case, help pages appear with information on the selected element. Method step-by-step To demonstrate the set-up in practice, the following example shows step-by-step how to generate a method. The example is for the Cooled Injection System (CIS) GC inlet combined with liquid injection based on the MultiPurpose Sampler (MPS). Step 21 Select Sampler Now select the MPS as sampler; when the MPS has been selected you can select the relevant parameters for liquid injection. For this purpose, select the menu item GERSTEL – Select Sampler from the menu line. The window Select Sampler opens. Select MPS from the list. Step 31 Parameters for liquid injection From the menu bar, select the menu item GERSTEL – Edit GERSTEL Parameters. The window GERSTEL Parameters opens up, displaying the parameters System Settings. At the bottom left, click on the MPS button. The parameters for liquid injection are shown on the tab page Liquid Injection Settings. Enter the required method parameter values. If you want to add rinse steps, to rinse the syringe between injections, click on the tab Rinse Settings – this will open up the page with rinse parameters. Indicate for each type of rinse, when it must take place and from which wash vial the rinse solvent should be taken. Preclean rinses, as the name implies, are performed prior to injection, post-clean, after the injection. Please note: Rinsing with sample can only be selected for pre-clean, not for post-clean. Now please switch to the CIS page. Step 41 Enter CIS parameters At the top left, click on the CIS button and the method parameters for the CIS are displayed; enter the desired CIS parameters. Should a parameter value lie outside the permitted range, the software will respond with a warning. If the parameter value is changed to fall within the allowed range, the software will accept the value. By clicking OK, the parameters are accepted and are uploaded to the controller. The CIS is now ready to start. Close the window. Step 51 Save method Now all you have to do is save the parameters in a named method, which you can load again later and use as basis for the analysis sequence. Save and name the method and then proceed as you would normally do when working with the ChemStation without integrated MAESTRO software. You are now ready to go! Select CIS with the mouse to set the parameters of the Cooled Injection System (CIS). Step 11 Start MAESTRO Let’s assume you work with the Agilent Technologies ChemStation software. When you start ChemStation, the integrated MAESTRO software is automatically started in the background. Switch on all hardware components before starting the software. Parameters for the liquid injection can only be set after you have selected Multi Purpose Sampler (MPS). Otherwise, the MPS parameter window will not be displayed. The GERSTEL MAESTRO software runs in the background when operating the Agilent Technologies ChemStation software. MAESTRO can operate with any standard software in “standalone” mode.
