Notice: University of Arkansas; Notice of Decision on Applications for
Duty-Free Entry of Scientific Instruments Federal Register: March 4, 2010 (Volume 75, Number 42)
Page 9868Agency: DEPARTMENT OF COMMERCE
International Trade Administration
This is a decision pursuant to Section 6(c) of the Educational,
Scientific, and Cultural Materials Importation Act of 1966 (Pub. L. 89-
651, as amended by Pub. L. 106-36; 80 Stat. 897; 15 CFR part 301).
Related records can be viewed between 8:30 a.m. and 5 p.m. in Room
3720, U.S. Department of Commerce, 14th and Constitution Ave., NW.,
Washington, DC.
Comments: None received. Decision: Approved. We know of no
instruments of equivalent scientific value to the foreign instruments
described below, for such purposes as this is intended to be used, that
was being manufactured in the United States at the time of its order.
Docket Number: 09-068. Applicant: University of Arkansas,
Fayetteville, AK 72071. Instrument: Fluorescence Lifetime Imaging
Microscope. Manufacturer: PicoQuant Photonics, Germany. Intended Use:
See notice at 75 FR 3895, January 25, 2010.
Reasons: The instrument must be able to perform using lasers with
both continuous wave (CW) and pulsed mode. The use of picoseconds
pulsed lasers is necessary to measure fluorescence lifetime. The use of
CW lasers, so that the fluorophores will be continuously excited, is
necessary to measure fluorescence intensity. The driver that controls
the laser head provides user-selectable pulsed repetition rates. This
instrument is unique in that it is capable of pulsed interleaved
excitation (PIE)--Fluorescence Resonance Energy Transfer (FRET) and of
allowing repetition rates to be continuously varied down to the 200 kHz
range. Furthermore, the instrument is compatible with atomic force
microscopy by using objective scanning mode rather than sample scanning
mode so that the sample-scanning Atomic Force Microscope (AFM) can be
added to the microscope in a future upgrade.
We know of no Fluorescence Lifetime Imaging Microscopes being
manufactured in the United States at the time of order of this
instrument.
