The Method Set Editor displays the method set entries (Figure 3-14). Figure 3-14 Method Set Editor 3 7. Click the Close button. Run Samples reappears with the Single window tab displayed (Figure 3-1). 3.1.3 Injection Volume in Run Samples The injection volume displayed in Run Samples can be expressed as an actual volume or as the number of plunger steps injected by the GC. You can specify the syringe size and presence of the nanoliter adapter for the front and back injectors. When you set these parameters, <strong>Empower</strong> software calculates the actual injection volume. Otherwise, the injection volume shown in the Run Samples window is expressed as a raw value of the number of plunger steps injected. The actual injection volume for a given number of plunger steps can vary significantly based on your injector configuration. We recommend specifying the injector parameters for your system so that the actual injection volume is displayed in Run Samples. You can set these parameters as defaults or as independant values for samples or single injections. Creating an Instrument Method 38
Figure 3-15 GC Syringe Size Parameters Window To set default syringe size parameters: 1. In Run Samples, select Customize > Defaults. The Run Samples Defaults window appears. 2. Click GC Syringe Info Define. The GC Syringe Size Parameters window appears (Figure 3-15). 3. Select Use parameters to check injection volume. The syringe fields are activated. 4. For each syringe (front and back injector): • Select the syringe size from the Size list. • If the injector is equipped with a nanoliter adapter, select the Nanoliter Adapter check box. 5. Click OK to close the GC Syringe Size Parameters window. 6. Click OK to close the Run Samples Defaults window. You can also set syringe size parameters for a sample set or for a single injection. The sample set and single injection syringe parameters are independant. To set the syringe size parameters for a sample set or single injection: 1. In Run Samples, click the appropriate tab (Single or Samples). 2. Select Edit > GC Sample Set Info. The GC Syringe Size Parameters window appears (Figure 3-15). 3. Select Use parameters to check injection volume. The syringe fields are activated. 4. For each syringe (front and back injector): 3 Developing Methods Using Wizards 39
