Shimadzu UK Ltd is strengthening its
position in the UK spectroscopy sector by creating a new benchmark in molecular
spectroscopy. The company's new Lo-Ray-Ligh diffraction grating heralds
the first serious advance in grating technology for many years and paves the
way for lighter, more compact instruments in the reference and upper research
sectors.
The new grating, which was created
by Shimadzu R&D in Japan, uses the company's new holographic exposure
method and optimized etching process to make it possible to produce both highly
efficient and exceptionally low stray light gratings.
The breakthrough grating technology
is now installed in Shimadzu's new UV-2600 and UV-2700 model UV
spectrophotometers. The UV-2600 is a single monochromator system, which
is able to read to 5 Absorbance, and offers a wavelength range to 1400nm with
the newly developed dual-detector ISR-2600 Plus integrating sphere.
The instrument's high performance
figures eclipse conventional spectrophotometers in both absorbance and
wavelength range, whilst also providing baseline flatness and noise performance
at least equal to any but the most expensive reference grade instruments.
The new Shimadzu UV-2700 takes
compact spectrophotometers to even greater levels, using a dual-monochromator
to extend the linear dynamic range to in excess of 8 Absorbance. Until
now only the most expensive, full-size reference grade instruments have been
able to deliver such performance. The UV-2700 is a third of the weight
and size of the full-size reference grade systems.
"The new spectrophotometer is ideal
for research groups focused on analysis in the near infra-red (up to 1400nm)
such as carbon nanotube and communications applications," explains Dr. Robert
Keighley, Shimadzu's Spectroscopy & TOC Business Manager.
"The new instrument offers a cost
effective alternative to the much larger UV-Vis-NIR spectrometers which were
previously required to cover this wavelength range. The range 900-1400nm
was always the most challenging for dual-detector PMT/PbS detector instruments
but Shimadzu has applied PMT and InGaAs detection in the ISR-2600 to ensure
high sensitivity and an excellent response rate when dealing with this
wavelength region".
