Here we present newly developed amplifiers equipped with 1013 ohm feedback resistors for the Thermo Scientific™ Triton Plus™ TIMS, Neptune Plus™ MC-ICP-MS and Noble Gas product line. A revolutionary new current amplifier design compensates for settling time effects observed with high-gain current amplifiers using high ohmic resistors in the feedback loop.
