Apex – High Sensitivity Desolvating Nebulizer

The highly successful Apex systems maximize ICP & ICPMS sensitivity by increasing sample transport efficiency while also enhancing stability.

Apex Highlights

  • Apex systems maximize sensitivity by up to 10x by nebulizing liquid samples first into a heated cyclonic spray chamber
  • Then multi-stage Peltier-cooled condensing chambers remove much of the solvent vapor, reducing solvent load on the plasma
  • Apex Omega & Apex 2 systems have complete software control of all system variables
  • Apex Omega provides the ultimate performance with two stage desolvation (Peltier-cooled and EPTFE membrane) to significantly reduce oxides with increased solvent removal (0.01% CeO+/Ce+)
  • InterClean accessory provides automated cleaning and conditioning for Apex Omega and Apex 2
  • Classic Apex systems also available (Apex Q, Apex IR, & Apex HF)

microFAST Isotope

Precision measurements call for precise sampling. The microFAST Isotope system offers all of the features of the microDX autosampler with the additional functionality of syringe-controlled sample loading and sample injection. Precise control of sample volume and flow rate means stable signal profiles can be measured from as little as 5 μl of sample or flow rates as low as 5 μl/min.

  • microDX autosampler with dedicated clean enclosure
  • Equipped with single or dual loop FAST capabilities & syringe sample loading / injection
  • Combine with Apex 2 or Apex Omega for enhanced sensitivity and low blanks

Autosampler Enclosures

When your samples and your laboratory environment shouldn’t mix. All ESI DX autosamplers offere available enclosures to prevent samples from becoming contaminated by airborne dust and particulates. These also feature a vented duct connection port if required for fume/vapor exhaust.

  • Protects samples from airborne contamination
  • Exhaust acidic fumes
  • Clear acrylic construction for easy sample viewing
  • Large hinged door for easy access

ULPA Air Filter

For maximum protection against sample contamination right up to the moment of analysis, an optional ULPA high purity air filter can be added to the enclosure of a microDX, 2DX or 4DX autosampler. The positive pressure air flow ensures sample integrity during analysis.

  • ULPA (Ultra-Low Particle Arrester) filter creates clean positive pressure environment
  • Removes 99.999% of 0.12 micron particles
  • Fits on enclosures for microDX, 2DX, and 4DX autosamplers
