Get the most out of your ICP-OES instrument with the CETAC U5000AT+ Ultrasonic Nebulizer. The U5000AT+ offers up to 10x lower element detection limits for aqueous samples. Samples are introduced onto a piezoelectric transducer, providing greater analyte transport efficiency to the plasma. An integrated desolvation system with electrothermal cooling removes excess sample aerosol solvent and ensures stable plasma operation.

Performance

The U5000AT+ converts more sample into useable aerosol, with an efficiency of 10–15% versus 2–3% for conventional pneumatic nebulizers. The result is up to 10x improvement in analyte signal and detection limits. For example, Figure 1 depicts an approximate 8× enhancement in signal for antimony (Sb) using the U5000AT+ with ICP-OES detection. For ICP-OES detection, limits fall below 1µg/L for many elements. For ICP-MS sub-ng/L limits can be achieved; even lower limits may be obtained under clean-room conditions. Short term (60 minute) and long-term (8 hour) stability is excellent, with %RSDs typically < 1%.

Fast and Easy Setup

Each U5000AT+ comes with an interface kit for easy connection to the host ICP-OES or ICP-MS. Setup can be completed in about 5 minutes.

Convenient Features

The U5000AT+ has a compact footprint for placement on a benchtop or laboratory cart. Modular design allows easy replacement of the entire glassware assembly. This unique feature is useful for switching between very different sample types. An optional membrane desolvator (MDX-200) can be added for further removal of sample solvent (aqueous or volatile organic).

Simple Operation

With the press of a button, the U5000AT+ generates sample aerosol; an integrated autotuning oscillator provides stable operation so no adjustment is typically needed between different liquid sample types. (See video below.) Dedicated, front mounted temperature controllers (Heater and Cooler) can be quickly reset for aqueous or organic applications. The U5000AT+ does not require computer control from the host ICP-OES or ICP-MS instrument. For automated sample introduction, the sample inlet tube of the U5000AT+ can be easily connected to an autosampler sample probe.
