Description
Alumen 450? is a
turn-on
fluorescent sensor, meaning that the solution fluorescence increases as a function of the concentration of dissolved Aluminum. Alumen 450? can re

ly be excited over a broad wavelength range from 280-400 nm with an extinction coefficient of 8300 ± 600 M
-1
cm
-1
at 318 nm. The fluorescence emission is very strong in the presence of Aluminum ions, centered at?≈ 420 nm.
Alumen 450? ready chelates dissolved Al
3+
and subsequently shows an increase in the emission spectra for Alumen Blue? in the presence of dissolved Al
3+
, i.e. it gets significantly brighter.? The probe increases its fluorescence emission > 300% in going from 0?→ 750 ?M Al
3+
.? Alumen 450? shows an almost linear response to Al
3+
from 1?→ 300 ?M dissolved Al
3+
. Alumen 450? is also a highly selective probe for both the detection and determination of dissolved Al
3+
over other dissolved cations.
In this kit, Alumen 450? is already conveniently preloaded into a box of 100 plastic cuvettes (transmission down to 285 nm). These cuvettes allow for dissolved Aluminum detection in a Fluorescence based format. With these convenient pre-loaded cuvettes, there is no reconstitution procedure necessary, simply add 3 ml (3cm
3
) of your sample to each cuvette and measure, it’s that simple.
For optimum performance, probe vials should be stored at -2 to -8 °C when not being used and < - 20 °C long term. Probe solutions should be used after dilution.
