Spectrometry - Spectrophotometry : EXP200140 or EXP200141
Référence : EXP 200 140
The SPID spectrometer is designed to study simple components belonging to the light spectrum of various light sources: spectral lamps, steady sources, lasers, standard lamps, etc. It is also used to study filters, solid or not, in transmission or absorption. An absorption model allows you to implement with ease Beer Lambert’s law and to observe chemical kinetic curves. Supplied with feedback material, this device will also provide you with ideas to implement your own hands-on exercises.
SPECTRUM STUDIES
Optical fibres allow great freedom of movement. Used for demonstrations during classes, they will let you move
from source to source easily. The simple, intuitive software, with its multi-station system, allows measurement and
superimposition of curves. It is ideal for showing the gases making up different bulbs, such as mercury in energy saving
light bulbs. Combined with a video projector, the SPID spectrometer will prove indispensable in your classes. Three
display modes, simple, coloured and spectroscope mode, are available.
COLOURED FILTER SPECTRUM STUDY
To study colour filters, all you need is a continuous Spectrum source, normally a halogen, two optical stands and a
fibre-holder token delivered with the spectrophotometer. The software allows you to create a reference and to implement solid or liquid filters by simply positioning them in front of the motionless fibre. The transmission or absorption curve is immediately displayed on the screen. You can show colour synthesis in a new way and study the principle of interference filters.
3D CHEMICAL KINETICS STUDY
Previously, your students were not necessarily able to build p a scientific approach using kinetics. You had to teach them
a Lambda max. Henceforward, you can ask them to choose hemselves a lambda according to the data of the product to
be studied, before going back to the exact lambda max that hey are now able to measure. All this is thanks to the fact that
the spectrophotometer observes all wavelengths in real-time and displays them in 3D. You can now browse through your cquisition at any time and at all wavelengths.
