 Overview

The U6000AT+ adds a membrane desolvation module to the standard U5000AT+ Ultrasonic Nebulizer for improved reduction of solvent-based interferences, particularly for volatile organic solvents (both polar and non-polar types).

Use with ICP-AES:  For ICP-AES the U6000AT+ is used primarily for the introduction of volatile organic solvents.  These solvents can cause a number of serious problems: loss of plasma, plasma instability, high carbon emission background, and carbon buildup on the ICP torch.

Use with ICP-MS:  For ICP-MS the U6000AT+ can be used for both volatile organics and aqueous samples

Higher Nebulization Efficiency:   The piezoelectric transducer of the U6000AT+ converts more of the liquid sample into a usable aerosol, with an efficiency of 10-15%.  With the membrane module connected, the result is a 2x to 5x enhancement of analyte signal vs. a standard pneumatic nebulizer.

Reduced Solvent-Based Interferences:  The inert, fluoropolymer membrane desolvator reduces solvent based interferences from water and organic vapor.  For example, the % CeO/Ce is typically <0.05% for water-based samples with the U6000AT+.  Carbon-based inerferences such as 12C2+ are also greatly reduced, allowing detection of Mg at m/z = 24.

Improved Detection Limits:  the combination of signal enhancement and reduced interferences enables lower instrument detection limits for both ICP-AES and ICP-MS.

Easy Setup:  All U6000AT+ units are provided with an interface kit for quick and easy connection to the host ICP-AES or ICP-MS.  The kit includes a nebulizer gas line and a sample out line with the appropriate ICP torch adapter.  In addition, a rinse kit is included for cleaning the membrane desolvator.

Compact Design:  The U6000AT+ consists of the standard U5000AT+ Ultrasonic Nebulizer and a modular membrane desolvator box.  The U5000AT+ is simply placed on top of the desolvator box, conserving valuable benchtop space; the footprint of the U6000AT+ is 35.6 cm W x 34.9 cm D.

Flexibility:  The membrane desolvator module can be easily disconnected from the ultrasonic nebulizer if membrane desolvation is not necessary for a particular application.  This feature allows stand-alone operation of the ultrasonic nebulizer.

Optional Blend Gas Accessory:  An optional blend gas accessory, the CETAC BGX-100, is available to help prevent carbon build-up on the ICP torch and ICP-MS sampling cones during extended introduction of volatile organic solvents.
