Coupled with a CETAC Autosampler, the ASXPRESS™ minimizes times for sample delivery, stabilization and washout, increasing throughput up to 5 times or more. By reducing sample delivery, stabilization and washout times, the ASXPRESS™ optimizes sample introduction and reduces costs from materials, power, maintenance and labor.

• Increase Sample Throughput
• Reduce Sample Uptake, Stabilization
  and Washout Time
• Reduce Sample Waste
• Lower Argon Consumption
• Reduce Sample Matrix Exposure on ICP Hardware
• Eliminate Sample Memory Effects

PRINCIPLE OF OPERATION
The ASXPRESS™ Rapid Sample Introduction System increases sample throughput for ICP-AES and ICP-MS analysis by reducing sample loading, signal stabilization and washout times. Using proven technology, the ASXPRESS™ combines a metal-free, 6-port injection valve and inert, high-speed vacuum pump to rapidly load the sample loop for introduction to the nebulizer. The design of the ASXPRESS™ facilitates quickly rinsing the sample loop while simultaneously injecting sample into the ICP-AES or ICP-MS nebulizer for analysis. The segmented stream washout technology effectively cleans liquid flow paths more completely and in less time. The result is additional time dedicated to sample analysis, more effective flow path rinse, and reduced time between samples .*

Load Position: The sample loop is loaded
with sample via the autosampler uptake.

Inject/Rinse Position: The loaded sample is pumped to the nebulizer for analysis while the autosampler probe is moved to the rinse station and is washed.

Increase Throughput

• More sample throughput in less time by optimizing sample introduction
• Virtually eliminates stabilization time by removing the need for “fast pumping,” improving plasma stability

Reduce Maintenance

• Extend the service life of ICP-AES/ICP-MS components such as nebulizers, spray chambers, and sample cones by reducing their exposure to the sample matrix

Cost Effective

• Minimize sample consumption
• Reduce laboratory costs associated with argon and power consumption, peristaltic pump tubing replacement, and maintenance

Simple Operation

• Easy set-up with minimal modification to the analysis method
• No additional complex software required; all system parameters are stored in the system’s on-board processor

COMPATIBILITY
The ASXPRESS™ is compatible with the CETAC ASX-520, ASX-520HS, ASX-260 and EXR-8 Autosamplers.

The ASXPRESS™ PLUS is compatible with the CETAC ASX-500, ASX-510, ASX-1400 and ASX-1600 Autosamplers.

Both integrate with most ICP and ICP-MS systems and can be easily added to samplers currently in operation.

Either model may be purchased as a complete system along with choice of autosampler or as an upgrade to autosamplers already in operation.

Please contact CETAC for more information on the above listed autosamplers or in regards to operating an ASXPRESS™ system on non-CETAC autosamplers.
