Spectra from Printer Station Room 230

Technology updates
are required for the old plotters and printers used for data output
from both the Gemini 200 NMR spectrometers (building 65 rooms
38 and 130), the UV/VIS spectra from diode array spectrometers
such as the HP-8452A found in room 230, and the infrared FTIR
spectrometer, PE 1720X, also located in building 65 room 320.
The plotters in use when the instruments were new are no longer
manufactured and parts are difficult to find. The new printer
station bring the departmental technology from the 1980's to the
21st century.
New printers/plotters have been obtained for the 300, 400, and 500 MHz NMR analyzers.
Another data station is also used to
obtain quality hard copy of spectra from NMR, UV/VIS, or FTIR
data. The data station is located in building 65 room 230 on a
metal cart. Obtain spectra, save it on a formatted 3 1/2"
floppy disk, and bring it to the data station for processing.
The following procedures are used to save spectral data onto a
floppy.
I. FTIR -- Drag and drop the FTIR data
file onto the icon for the 3 1/2" floppy in B Drive. Then
import the *.SP file into the Spec Manager. Once a file is imported
and saved it becomes an *.ESP file which is opened directly by
the manager.
II.
UV/VIS -- Use the DOS program Valet manager to copy data
files. During the log on process select the Valet Utility and
ask Valet to copy any already saved *.WAV file. Copy to the 3
1/2" B drive. Use B: to designate the drive. Data are located
in the directory named C:\HPUV\Data. Use ESC to exit the Valet
manager. Once the file is imported and saved in Spec Manager it
will be converted to a file with an ESP extension.
III. NMR -- Use the file Explorer to copy requisite
DAT files from the NMR Spec Manager at the data station in room
130 onto a 3 1/2" floppy. The data can be processed either
in room 230 or 130. Data from FTIR or UV/VIS spectrometers can
only be processed in room 230. Specific instruction to convert
Gemini FID files must proceed the printing process.
Specific
procedures for processing NMR spectra have been described. The
procedures for processing FTIR and UV/VIS spectra are also similar.
The following maybe useful hints on how to successfully process
spectra.
1. The Y-axis of the spectra can be modified by selecting
the Transformation command the selecting any of the options such
as Transmission, %Transmission, Absorbance, etc. This
is especially important when the axis is labeled Relative.
2. The X-axis of the spectra can be modified by selecting Cut Off Region under Process then
select Region Boundaries and then Cut and Save the modified spectra. This techniques is important when there
are high signals are observed, at one end of the x-axis.
