prepFAST S – Automated Introduction of Pure Semiconductor Chemicals

The prepFAST S has revolutionized the way ultrapure semiconductor grade chemicals are analyzed with ICPMS detection. The prepFAST S utilizes syringe-driven flows of UPW, semiconductor grade acids, and standard solution to automate both sample dilutions and standard curve generation. It eliminates manual handling of samples and standards to deliver sub-ppt detection limit capabilities.

Automated Inline Sample Dilution

  • Removes interaction with dangerous chemical during manual dilution process
  • Removes contamination event from pouring sample into a new bottle for dilution
  • Improves dilution reproducibility

Automated Inline Standard Preparation

  • Removes contamination when creating MSA calibrations
  • Improve throughput by quickly calibrating the ICPMS for each chemical – down to single digit-ppt range

Syringe Driven Sample Injection

  • Consistent injection flowrate compared to self-aspiration
  • High speed washing of ICPMS spray chamber greatly reduces time to switch chemicals

Fluoronetic Autosampler

  • Magnetically coupled fluoropolymer linear drive eliminates exposed metal surfaces inside the enclosure
  • All fluoropolymer autosampler rail reduces contamination
  • Compatible with large range of bottle sizes (<1 mL - >500 mL)

Fully Enclosed Environment

  • Provides clean room grade results without the clean room
  • Removes hazardous fumes from room
  • Continuous flow of ultra-pure water (UPW) for maximum purity

Unmatched Nanoparticle Detection

Benefits:

  • Improve Sample Homogenization:
    • Homogenizes sample to improve accuracy and reproducibility of nanoparticle analysis
    • Mobilizes nanoparticles back into solution
  • Optimize Nanoparticle Suspension:
    • Chilled environment for optimal suspension of nanoparticles
    • Automatically homogenizes reference material solution before each analysis
  • Eliminate Nanoparticle Deterioration:
    • Automatically adds reference material at time of analysis
    • Eliminates nanoparticle deterioration in chemicals
