Removing Dead Volume
  • Nebulizer EzyFit
  • Spray chamber Helix
  • Internal Standard Low volume chamber

4
Software Approaches to Speeding Analysis
  • Fast pump in rinse mode
  • longer equilibration
  • Predictive Rinse
  • QCs complicated
  • Risk of carryover
  • Intelligent Rinse
  • Analyzes rinse to determine optimum time
  • Rinse is based on sample results
  • Modest productivity gain

5
Niagara Rapid Rinse Accessory
  • Interfaces between ICP Autosampler
  • Reduces required rinse time
  • Programmable delay time
  • Less than 8 inches high
  • Includes adj. height stand

Niagara Interface no software required
  • Started with hardware trigger on AS
  • Recently modified to serial interface
  • Serial cable runs from ICP computer through the
    AS to the Niagara.
  • Each Niagara is preprogrammed for a specific
    ICP/AS combination.

Summary
  • Decrease dead-volume in sample introduction
    system to reduce rinse time
  • Software approaches produce marginal productivity
    improvements
  • Niagara produces clear gains in productivity
    leading to marked increases in instrument
    throughput and per instrument revenue generation.
