The Anasazi EFT-60
The Anasazi EFT-60 was
installed in April, 2000. It is an
upgrade of a Varian EM360L CW instrument.
A C13 accessory was installed with the upgrade. All of the original controls have been
replaced by a standard microcomputer and two units from Anasazi
Instruments. Only the “box”
containing the original magnet and sample compartment remains from the
original Varian instrument. Acknowledgement -
Funding for this instrument was made possible through the Special Projects
Grants in Chemistry program of the Camille and Henry Dreyfus Foundation with
matching funds from the Office of the Vice President of Instruction and the
College of Southern Idaho Foundation, Inc.

Major Components
The “box” containing the magnet (1.4 Tesla) and sample
compartment is the large unit on the right next to the lab bench. Next to it on the floor are the two
Anasazi control units. A Micron
microcomputer sits under the table.
The table holds the monitor, HP printer, mouse and keyboard. |

The WinPNMR Program
The instrument is controlled by the WinPNMR program. Parameters are entered in this program and the experiment is then executed. The program collects data in the form of a free-induction decay signal (FID) as shown in the illustration. |
|
||||||
The WinNUTS Program
When data collection is
complete the FID is transferred to the WinNUTS program. WinNUTS performs a Fourier transform on
the FID to generate a conventional NMR spectrum. At this point the spectrum is usually just printed, but WinNUTS
has many other features for processing and presenting the data. It is also handles 2D NMR and other
advanced techniques. |
