ASXpress Plus

When coupled to a compatible autosampler, the ASXPRESS® PLUS Rapid Sample Introduction Accessory minimizes times for sample delivery, stabilization, and washout with ICP-AES or ICP-MS.  The result is increased sample throughput by up to 5 times or more.  In addition, the ASXPRESS® PLUS reduces costs from argon, power, ICP-AES / ICP-MS components, and system maintenance.
Omschrijving

When coupled to a compatible autosampler, the ASXPRESS® PLUS Rapid Sample Introduction Accessory minimizes times for sample delivery, stabilization, and washout with ICP-AES or ICP-MS.  The result is increased sample throughput by up to 5 times or more.  In addition, the ASXPRESS® PLUS reduces costs from argon, power, ICP-AES / ICP-MS components, and system maintenance.

Key Advantages of the ASXpress PLUS:

  • Increase sample throughput
  • Reduce sample delivery, stabilization and washout times
  • Shorten sample batch run times
  • Reduce sample waste
  • Lower argon consumption
  • Reduce electrical power use
  • Reduce sample matrix exposure on ICP-AES / ICP-MS hardware
  • Eliminate sample memory effects from peristaltic pump tubing

The ASXPRESS® PLUS Rapid Sample Introduction Accessory is compatible with all Teledyne CETAC autosamplers and several autosamplers from other manufacturers. Detailed compatiblity information can be found below.

Principle of Operation

The ASXPRESS® PLUS Rapid Sample Introduction Accessory increases sample throughput for ICP-AES and ICP-MS analysis by reducing sample loading, signal stabilization and washout times. Using proven technology, the ASXPRESS® PLUS combines a metal-free, 6-port injection valve with a sample loop and an inert, high-speed vacuum pump to rapidly load a sample aliquot prior to introduction to the standard nebulizer. The design of the ASXPRESS® PLUS facilitates rapid rinsing of the sample loop while simultaneously introducing sample to the ICP-AES or ICP-MS nebulizer. The segmented stream washout technology cleans liquid flow paths more completely and in less time. The result is additional time dedicated for sample analysis.

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

Inject/Rinse Position: The loaded sample is pumped to the nebulizer for analysis by the host ICP-AES or ICP-MS while the autosampler probe is moved to the rinse station and is washed.

​Details of ASXpress PLUS Advantages

Increase Throughput

  • Increase sample throughput in less time by optimizing sample introduction steps
  • Virtually eliminates stabilization time by removing the need for "fast pumping," improving plasma stability

Reduce ICP-AES and ICP-MS Maintenance

  • E​xtend the service life of components such as nebulizers, spray chambers, and ICP-MS sampling cones (sampler and skimmer) by reducing their exposure to the sample matrix

Cost Effective

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

Simple Operation

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

Compatibility

The ASXPRESS® PLUS Accessory is compatible with the CETAC ASX-500, ASX-510, ASX-520, ASX-560, ASX-260, EXR-8, ASX-1400 and ASX-1600 Autosamplers, PerkinElmer S10 and AS-93 PLUS Autosamplers, and Agilent SPS3 Autosampler.  

The ASXPRESS® PLUS accessory integrates with most ICP-AES and ICP-MS systems and can be easily added to autosamplers currently in operation.  The ASXPRESS® PLUS may be purchased with choice of Teledyne CETAC autosampler or as an upgrade to autosamplers already in operation.
