HE-SIS for Nu Vitesse

Glass Expansion's HE-SIS (High Efficiency Sample Introduction System) was initially developed as a cutting-edge solution for single-cell sample analysis. Our dedicated team of experts have recently enhanced its design to deliver exceptional performance in a diverse range of applications. Whether you're conducting single-cell studies, analyzing single particles, investigating nanoparticles, or working with low-volume samples, the redesigned HE-SIS ensures remarkable results with an impressive transport efficiency of up to 95%. Experience superior performance and unparalleled versatility with Glass Expansion's HE-SIS.

Key HE-SIS Components

Conventional ICP-MS spray chambers have low transport efficiencies (typically < 5% TE) that filter out larger droplets (> 5µm) from the nebulizer aerosol. The Glass Expansion HE-SIS features three critical components to overcome this significant sample transport deficiency.

• (a) MicroMist™ HE Nebulizer

  This specially designed concentric glass nebulizer is based on our popular MicroMist design, capable of efficiently nebulizing limited sample volumes at low sample and argon gas flow rates.

• (b) MicroJet™ Gas Adapter

  Our MicroJet gas adapter (Patent approved) shapes the nebulizer aerosol plume to reduce sample deposition on the spray chamber walls and enhance transport efficiency.

• (c) Lotis™ HE Spray Chamber

  The Lotis HE spray chamber directly couples to the ICP-MS torch, providing the highest transport efficiency and excellent washout between samples.
