Lab Exercise: Spectral Libraries

Building a Library

11) Click on Name and type in Dimethylphthalate. (Do not press Enter, as

doing so will complete the entry.)

12) Other fields are present that you can use to customize your entries. Find the

Sample entry and fill in Test Mix.

13) Scroll down until you find Slit Width. This parameter may be found on the

Set up DAD Signals screen under the Instrument menu in the Method and

Run Control view. Fill in the applicable width: 1, 2, 4, 8, or 16 nm.

14) Explore the Edit Wavetable. Select Autom. Note that it labels lambda max.

This data is useful for spectral comparisons.

15) OK the Edit Wavetable dialog box and then Add the spectrum to the library.

The next spectrum you chose now appears.

16) Fill in the name of the compound, Diethylphthalate. Fill in the remaining

information requested. Select Add to add the spectrum to the library.

17) Now add the information for spectra for peaks 3 and 4 to the library. Peak 3 is

Biphenyl and peak 4 is o-terphenyl. You now have a library with 4 spectra.

OK the Add Entries dialog box.

18) View your library entries by pulling down the Spectra, Library, Manage

Entries… menu selections or click on the Change Spectra Entries of the

Current Library tool.

19) Select Biphenyl, then Show Spectra. The spectrum is displayed. OK this

dialog box. Note that you can delete or edit entries. You may also copy the

spectrum to the spectral window of Data Analysis (Copy Spectra). When

you have finished exploring, OK the Spectra Library Manager panel.

20) Save the library with the Save Current Library File tool or through the

menus: Spectra, Library, Save Library.
