Waters HPLC Empower software installation Step by Step guide.
This procedure will step you through the basics of running 2D analysis with Empower using the QuickStart interface. You will set up an instrument method, method set, and sample set to prepare to run a sample. Make a processing method in review and setup basic analysis. Batch process the sample set, and then preview the result for a peak area and amount.
1. Login to Empower
a. Double click on the Empower icon.
b. For User Name: System, For: Password: Manager – click OK. In the Requested Interface select: QuickStart
c. Click Ok and select the desired Project and system then select OK. You will be logged into the QuickStart interface of Empower.

5. Click on the 2996 icon (or other 2D detectors). Select 2D data collection and fill out the table as desired:
c. Select File – Save and enter the name of the instrument method as XXXX.
4. Make a default Processing Method and Method Set:
a. Click the Processing Method icon. The channels to process will be displayed. This is where chromatogram smoothing, offsets, and math calculations may be accomplished. Select OK.
b. From the menu bar, select File – Save All. You can save the processing method for channel 1 as “xxxx1” and the Method Set as “xxxxMS1”, which contains the instrument method and the processing method.
Note: An instrument method and method set must be created before acquiring any chromatographic data.
c. Click the Method Set icon, and in table area of the method set, scroll to the right and select the Report column. Select the default individual reports for each processed channel. Select File – Save to save the changes to the Method Set as “xxxxxMS1”.
5. Make a Sample Set and a Sample Set Method using the wizard.
a. Click the icon. If using the same method all the time, then from the menu bar, select Customize – Defaults. For the Instrument Method select the instrument method you just created. Repeat this for the Method Set. Enter in the desired default run time and printer preferences. Click OK. Then from the menu bar, select File- Save Preferences.
b. Click on New Sample Set Wizard. This will guide you through the basics of making a sample set including optional bracketing. Leave the Sample Set wizard type to LC PDA/MS and select Next.
c. Select standard injections to occur at the Start of the Sample Set. Click Next. Leave the calibration options to each standard vial contains a different level. Click Next.
d. In the standard bracket area, enter the following:
Number of Standards in each group: x; Number of Injections per vial: x; Injection Volume: x; Run Time: x; Method Set x; Click Options: In the Next Inject Delay enter in x. Click Next.
e. In the describe samples area, enter the following:
Number of Samples: x ;Number of Injections per vial: x ; Injection Volume: x ; Run Time: x ; Method Set x ; Click Options: In the Next Inject Delay enter in x. Click Next.
f. In the Identification, for the standard name, enter in Stan, and in the increment suffix use 1. For the sample name, enter in Soda and in the increment use a. Click Next.
g. Select the Run Mode to Run and Process, and select Next. Review the summary and click finish. The component editor will be displayed. Enter the component names in each standard vial. You will identify the names of the component with the peaks after acquiring the data using the processing method wizard.
i. Select OK after entering all component names and amounts.
j. From the menu bar select File – Save Sample Set Method and enter in Basic Analysis Set (this will save this table as a template for future analysis).
k. Click the Run the Current Sample Icon and select Run. Select the name for the Sample Set. The sample-set will start and the Running tab will be displayed with the first sample highlighted in red.
l. To see a real-time plot on the top right-hand area, select the Control Panel tab.
m. Click the View Acquisition tab twice to toggle between a real-time plot display and turning off this display. This display may be used or not used depending upon the user’s preferences.
6. Develop a Processing Method in Review:
a. Click on the Browse Project icon. Click on the Sample Set tab and select the desired Sample Set.
b. Right mouse click on the table and select View As Channels. This will display just the sample set as individual channels.
c. Highlight a standard sample & right mouse and select Review – Replace Data. The review section of Empower QuickStart will be displayed with the unprocessed chromatogram.
d. Click the Processing Method Wizard Icon. The first page of the wizard will be displayed. Select Create New Processing Method and click OK.
e. Confirm the Processing type is LC, and the Integration Algorithm is Apex Track. Click the Use Processing Method Wizard box, and click OK. Apex Track’s algorithm will detect peaks with a minimal amount of integration events.
f. Use the mouse to box and zoom in on the area of the chromatogram that you want peak detection and integration to occur. Click the Next.
Note: To unzoom Right-Click – then select Fullview from the selection list
g. The chromatogram will be displayed with the peaks integrated. Since this method is being used for samples that are of different amounts and this is not a regulated company, click Clear Peak and Threshold (this will change peak width and the threshold for each sample). Click Next.
h. To reject some of the detected peaks, click inside the smallest peak of interest, then click minimum height. There should only be the peaks desired integrated. Click the Next button.

8. Batch Process the Sample Set using the Process and Report Tool for 2D Data:
a. Click the Browse Project icon, then select the Sample Sets tab.
b. Right mouse click on the desired Sample Set and select Process ( you may also select injections or channels).
c. In the Processing area, click Use Specified Processing Method (or you may select use specified Method Set). Click the drop-down box & select the desired processing method (or Method Set). Click Clear Calibration. In How: select Calibrate and Quantitate.
d. In the Report area, make sure that the reporting box is checked as desired.
