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.
The ASX-112FR Flowing Rinse MicroAutosampler features a compact size, integrated protective cover and dual flowing rinse station for handling small volume samples (<2 mL) in a cleanroom environment.
The NX9000 FIB-SEM system allows the highest precision in material processing for a wide range of areas relating to advanced materials, electronic devices, biological tissues, and a multitude of other applications.
Several improvements and enhancements have been made to the latest HORIBA LAQUA handheld meters allowing sustained periods of operations in challenging outdoor conditions and making the 200 series a compact yet powerful versatile water quality meters.
The Oils 7600 Homogenizing Autosampler allows two sample matricies to be introduced to an ICP instrument from the same system. Boasting a dual port rinse station fed by two separate peristaltic pumps, it can change between oils and coolants testing on demand.
The LI-600 is a compact porometer with an optional Pulse-Amplitude Modulation (PAM) fluorometer that measures stomatal conductance and chlorophyll a fluorescence over the same leaf area.
The Benchmark XLT is designed to handle large area parts or nested groups of smaller parts using its moving bridge design. Advanced image processing allows the Benchmark XLT to operate with high speed, accuracy and robustness.
