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.
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.
Our MicroJet gas adapter (Patent approved) shapes the nebulizer aerosol plume to reduce sample deposition on the spray chamber walls and enhance transport efficiency.
The Lotis HE spray chamber directly couples to the ICP-MS torch, providing the highest transport efficiency and excellent washout between samples.
Superior Performance
In a comparison of the average sensitivity, Glass Expansion’s HE-SIS provided a factor of 2 to 3 increase compared to another commercially available single-cell or laminar flow sample introduction system (BrandX). The sensitivity ratio of the HE-SIS to BrandX was averaged for 16 masses, ranging low to high at a nebulizer sample flow rate ranging from 4 to 100 uL/min.
This increase in sensitivity is indicative of the high quality design of the Glass Expansion HE-SIS and MicroJet which greatly improves the transport efficiency compared to other commercially available systems.
