System Specifications

QuantMaster 30 sensitivity

The QuantaMaster™ 300 system equipped with a pulsed lamp and a gated detector is invaluable in boosting the detection sensitivity of otherwise almost undetectable europium emission obscured by fluorescence (trace at delay = 0) from organic ligand. By placing the detection gate 200 microseconds away from the excitation pulse, a clean spectrum of europium ion is observed (trace at delay = 200 μs), while the impurity fluorescence is completely suppressed.
