TU-1900/1901
UV-VIS Spectrophotometer
--------------------------------------------------------------
The
TU-1900 and TU-1901 is our company's highest performing
research-grade UV-VIS spectrophotometers. Its optical
system utilizes a double- beam dynamic feedback
ratio photometric recording system, a unique full-transmission/full-reflection
design, and a highly sensitive photomultiplier tube
as a detector. All operations are controlled through
the PC: automatic wavelength control, automatic
switch light-source control, and automatic
spectrum bandwidth control (TU1900 has set spectrum
bandwidth).
This
instrument features easily interchangeable holder
accessories and an open-type light source chamber
design. The software is operated under the WINDOWS
platform. The TU1900s UV-VIS spectrophotometers
perform photometric measurements, spectrum measurements,
and quantitative measurements. It is easily operated,
features excellent performance, automatic 900nm-190nm
wavelength scan, automatic peak-picking. Its convenient
and easy data processing is very suitable for medical,
chemical, environmental, agricultural, or biological
analytical work.

Features
*
Excellent performance. High-performance
blazed holographic grating and the optimized
CT-type monochromator minimizes stray light
and widens the photometric range in the TU-1900s.
*
Ideal baseline stability. Double-beam
dynamic feedback ratio photometric recording
system reasonably coupled with an advance
design electric control system ensures high
stability of the instrument baseline.
*
High resolution. The unique optic design
of full-transmission and full-reflection will
guarantee a clean separation of the light
source into a double beam while at the same
time energy enhancement will maintain the
light energy of both beams. This design reduces
noise and guarantees high resolution.
*
Accurate wavelength. The automatic
wavelength system and the automatic light-source
interchange systems ensure wavelength accuracy
and high holistic performance of instrument.
*
Easy accessories replacement. The detachable
design of the sample chamber easily facilitates
exchange of a wide range of optional accessories
and ensures satisfactory analysis of various
kinds.
|
Versatile
UV-Win software |
*
User-friendly arrangement. The open
design of the light source chamber, socket
deuterium lamp and socket tungsten halogen
lamp facilitates easy light source replacement,
easy maintenance, and reduces operation
error.
*
Versatile application software. The
UV-Win application software is made in the
Windows format, offering an extended range
of instrumental control and data processing.
*
Quality components. Many key components
are chosen from some of the world¨s best
manufacturers; these include the deuterium
lamp, PMT and holographic grating. Careful
selection of these components ensures the
instrument¨s dependability, accuracy, and
maximizes lifespan.

Note:
The TU-1800 features all the advanced functions
of the TU-1800S, but is simplified by removing
the selectable bandwidth feature. The TU-1800
will remain at 2.0 nm set spectral bandwidth while
the TU-1800S can analyze using four different
bandwidths.
