Time-resolved spectrum

Step scanning technique can be used to detect very fast the time schedule of the repetitive events (transient).Step by step and move to a separate interferometer moving mirror interference figure points, in every bit of the experiment will restart again.INVENIO and VERTEX series spectrometer using high precision scanner to control the quality of the interferometer, gain the remarkable time resolved data.

application

• Electron transfer research of biological compounds
• Kinetics of gas phase at a high speed
• The dynamics of geological layer between species
• Free radical intermediate state between the spectrum
• The combustion process dynamics
• Photolysis experiment
• Pump detection experiments
• Organometallic chemistry reaction kinetics
• Time resolved emission spectrum, such as photoluminescence, fluorescence, or pulsed laser emission.

A quick scan

To not repeat the experiment (for example, many chemical reactions) of time-resolved spectrum, and the step and scan method is no longer applicable.For such experiments, however, can also use the so-called time resolved data obtained rapid scanning technology.In this case, the interferometer mirror move very fast and from each complete bilateral double scanning can extract as many as four spectrum.

Due to the duration of a scan rate depends not only on moving mirror, still depends on the distance, thus can realize the number of spectral/SEC also depends on the spectral resolution.Equipped with a quick scan option, VERTEX 70 v and INVENIO spectra have been able to achieve more than 70 copies per second acquisition rate.In addition, based on innovative UltraScan^TMInterferometer of the VERTEX set the standard 80/80 v, can realize the collection of more than 110 copies spectra per second rate.

New: cross time-resolved spectroscopy

INVENIO and VERTEX series cross time-resolved spectrometer (TRS) acquisition mode is that some repeated high SNR time-resolved measurements of experimental method.Interferometer dynamic continuous moving lens, using internal HeNe laser zero point to trigger the experiment.Not only zero in each HeNe interference signals (t = 0) for data collection, and each of moving mirror distance He - Ne laser zero point at a specific time Δ t data acquisition.Therefore, the system will continuously for data collection, in principle can be collected in a scan a series of time-resolved interference figure.Cross time resolved FT - IR spectroscopy only brooke can offer.
