Model U5000AT+ - Ultrasonic Nebulizer for ICP-AES/ICP-MS Brochure

U5000AT+ Ultrasonic Nebulizer for ICP-AES/ICP-MSThe U5000AT+ Ultrasonic Nebulizer offers lower detection limits up to 10x lower detection limits for ICP-AES and ICP-MS. Samples are introduced onto a highly effi cient piezoelectric transducer, providing greater analyte transport effi ciency to the ICP.SENSITIVEHigher Nebulization Efficiency: Conventional pneumatic nebulizers are generally only 2-3% efficient under normal operating conditions. The U5000AT+ converts more of the liquid sample into a usable aerosol, with an efficiency of 10-15%. The result is up to 10 times improvement in analyte signal.Lower Detection Limits: For ICP-AES detection, limits fall below 1ppb for many elements. For ICP-MS, sub-ppt limits can be achieved. Even lower limits may be obtained under clean-room conditions.STABLEShort-Term and Long-Term Stability: Short-term (60 min.) and long-term (8 hour) stability is excellent, with %RSD typically <1%.Fewer Adjustments: The U5000AT+ has an auto-tuned power supply for stable operation. No adjustment is necessary between different sample types.EFFICIENTAn efficient electrothermal desolvation system is used instead of a re-circulating chiller. This prevents solvent overloading of the ICP, saves laboratory bench space and reduces maintenance. A built-in drain pump removes condensed sample solvent and excess sample liquid from the spray chamber.SIMPLEQuick Setup All U5000AT+ units are shipped with an interface kit for fast and easy connection to the ICP. The kit includes a nebulizer gas line for the host ICP instrument and an ICP torch adapter for the sample out line.Easy Operation: Once sample liquid is introduced to the U5000AT+, simply press the operate button to generate the aerosol.COMPACTBench-Top Operation: The U5000AT+ has a small footprint allowing for placement on a bench-top or laboratory cart.Modular Design: A modular design allows easy replacement of the entire glassware assembly. This unique feature can be useful when switching between very different sample types (ex. low dissolved solids versus high dissolved solids; aqueous versus organic).An optional membrane desolvator (CETAC MDX-200) can be added for further removal of sample solvent (aqueous or volatile organic).Place your order: CETAC.COM || SALES@CETAC.COM || PHONE 800.369.2822 || FAX 402.733.5292ICPAr InCondenserDrainDrainSample InHeated ‘U’ TubePRINCIPLE OF OPERATIONA peristaltic pump introduces liquid sample across an oscillating piezoelectric transducer. The oscillations disperse the sample into a fine aerosol, which is swept out of a spray chamber by a flow of argon gas from the host ICP-AES or ICP-MS instrument.The aerosol passes through a heated tube and an electrothermally cooled condenser. An integrated drain pump removes the condensed sample solvent and any excess sample liquid from the spray chamber.After passing through the condenser, the dried aerosol particles are swept by the nebulizer gas to the ICP instrument for analysis.Technical SpecificationsSample Uptake Rate: 0.5 to 2.5 mL/minNebulizer Gas Flow: 0.5 to 1.5 L/minHeater Temperature: 120°C to 160°CCooler Temperature: -20°C to +10°CVoltage: 100-120 VAC, 50/60 Hz, 4.5A 220-240 VAC, 50/60 Hz, 2.5ADimensions: Height: 25.4 cm (10")Width: 35.6 cm (14")Depth: 34.9 cm (13¾")Weight: 12.3 kg (27 lbs)Warranty: 12 month limitedSchematic of U5000AT+ USNClose-up of AerosolNEBULIZERSPAGE 43Place your order: CETAC.COM || SALES@CETAC.COM || PHONE 800.369.2822 || FAX 402.733.5292
