microFAST MC - Dual Loop Syringe Loading & Injection

The microFAST MC combines the advantages of the Micro DX autosampler with single or dual loop FAST capabilities and syringe based sample loading/injection. The system accurately loads a loop and then smoothly injects the solution into a μFlow concentric nebulizer at defined rates from 5-1000 μL/min. The valve on the flow injection system selects from two discrete, parallel flow paths. This allows rapid switching between solutions with minimal dead volume between the valve and the nebulizer.

  • Total sample consumption
  • Syringe load micro volumes (5-1000 µL)
  • Syringe inject at desired flow rate (5-1000 µL/min)
  • Dual loop system
  • Reliably run small volume samples at 5-1000 µL/min
  • Dual loop for high throughput and reduced carryover
  • Stable injection profiles for precise isotope ratios
  • Combine with apex 2 or Apex Omega for enhanced instrument sensitivity and low blanks

Autosampler Enclosures

ICP and ICPMS sample integrity is maintained with the ESI DX autosampler enclosures. The enclosures can be configured either as a dust cover or ULPA-filtered minienvironment.


  • Protects samples from airborne contamination
  • Exhaust acid fumes to protect the laboratory environment
  • Clear acrylic construction for easy sample viewing
  • Covers only the sample area—the electronics are kept outside the enclosure
  • Large hinged door provides easy access to sample racks at any time
  • Exhaust port (50 mm, included) connects to laboratory ventilation system
  • The ULPA (Ultra-Low Particle Arrester) filter upgrade is 99.999% efficient down to 0.12 microns

Enclosure Only With ULPA Filter Description
SC-1607-DX SC-1607-DX-1000 Enclosure for Micro DX Autosampler

ULPA - Ultra-Low Particulate Arrester Air Filter and Mounting Plate

The ULPA (Ultra-Low Particle Arrester) filter creates a clean, positive pressure environment for samples and standards and prevents airborne contamination. The ULPA filter removes 99.999% of 0.12 micron particles.

The ULPA filter mounting plate fits the 2DX, 4DX, Micro DX and microFAST-MC on either the right or left side of the enclosure.
