2. INTRODUCTION
TO THE Ultrospec
7000/8000/9000
SPECTROPHOTOMETER
The Biochrom Ultrospec 7000/8000/9000 are a range of standalone, easy to use,
dual beam UV-visible spectrophotometers with high resolution color touch screens.
All spectrophotometers offer a comprehensive range of spectrophotometric and life
science applications.
A spectrophotometer is an optical arrangement that is designed to pass light
energy through a sample. The reduction of transmittance of the light energy and
corresponding absorbance peaks, caused by the sample under test, can be used
in a qualitative way to determine sample composition or in a quantitative way, by
comparing with known concentration standards, to determine the concentration of a
sample. In other types of studies the tracking of absorbance over time can be useful
to study chemical reactions and biological processes.
The Ultrospec 7000/8000/9000 range of spectrophotometers are designed to
produce light energy from the far ultraviolet through visible light in the range
190 to 1100 nm. Many materials, and in particular solutions of materials will
absorb light energy within this region. This makes the Ultrospec 7000/8000/9000
spectrophotometers applicable to a wide range of market sector needs including
applications in Life sciences, clinical, pharmaceutical, cosmetics, food & drink,
agricultural, industrial, environmental, toxicology, water treatment and teaching.
There are a large number of published methods and assays available for these.
