Glass Expansion Nebulizers

Glass Expansion Nebulizers

Glass Expansion has been manufacturing sample introduction components for ICP emission and mass spectrometers since the early 1980s. Today they support instruments from 16 manufacturers, providing sample introduction systems for over 50 different ICP and ICP-MS models. Glass Expansion products are endorsed and supplied as original equipment by most of the major ICP and ICP-MS manufacturers, and are widely used and embraced by recognized analysts throughout the ICP industry worldwide.

Reproducibility of analytical results in ICP analyses is of paramount importance. In an environment where a small change or inconsistency in a product or variable can result in a dramatic change in analytical results, design quality and reliability is essential. Glass Expansion has developed unique and proprietary manufacturing methods, which enable the production of components with the high mechanical strength and micron-level dimensional accuracy to satisfy the narrowest of analytical specifications, each and every time. GE products are recognized worldwide for their excellent precision, cost effectiveness and reproducibility of results.

NEBULIZERS

All Glass Expansion concentric glass nebulizers use the unique VitriCone construction for the sample channel. With the VitriCone design, the sample channel is constructed from a heavy glass capillary which is machined to very high tolerances, resulting in a uniform sample channel dimension that is resistant to clogging. The rugged, precision-machined capillary resists vibration and delivers the best possible precision, and the industry's tightest tolerances ensure that each nebulizer will perform to the same high standards as the previous one.

Glass Expansion manufactures nebulizers to operate optimally at the gas pressures and flow specified by the instrument manufacturers. Rather than manufacturing nebulizers which operate within a certain gas pressure and flow range, GE manufactures their nebulizers in accordance with your ICP specifications.

Glass Expansion SeaSpray Nebulizers

The SeaSpray concentric nebulizer offers outstanding nebulization efficiency for trace level analyses. It offers freedom from clogging while nebulizing solutions to the limit of solubility of most mineral salts, and conferring significant sensitivity gains.

  • Material: Borosilicate glass
  • High physical reproducibility ~ 1%
  • TDS tolerance, typically up to 20%
  • High tolerance to particulates, typically up to 75um
  • Low RSD's due to highly accurate construction
  • Standard available uptake: 0.4ml/min and 2ml/min

Glass Expansion MicroMist Nebulizers

The MicroMist micro-uptake glass concentric nebulizer offers high performance for limited sample volumes. It makes routine ICP-MS Hg determinations possible and reduces matrix effects when used with Glass Expansion's Cinnabar spray chamber.

  • Material: Borosilicate glass
  • High physical reproducibility ~ 1%
  • TDS tolerance, typically up to 15%
  • Low RSD's due to highly accurate construction
  • Standard available uptake: 0.05, 0.1, 0.2, 0.4 & 0.6ml/min

Glass Expansion Conikal Nebulizers

The Conikal concentric nebulizer gives the most reproducible results for standard ICP analyses. It represents the choice nebulizer for high precision, routine aqueous and organic applications.

  • Material: Borosilicate glass
  • High physical reproducibility ~ 1%
  • TDS tolerance, typically up to 5%
  • High tolerance to particulates, typically up to 75um
  • Low RSD's due to highly accurate construction
  • Standard available uptake: 1, 2 & 3ml/min

Glass Expansion Slurry Nebulizers

The Slurry glass concentric nebulizer is ideal for specialized applications requiring the aspiration of slurries or suspensions. Its capillary bore is 50% larger than standard concentric nebulizer, reducing the possibility of particle blockage, while retaining excellent signal stability.

  • Material: Borosilicate glass
  • High physical reproducibility ~ 1%
  • TDS tolerance, typically ~ 1%
  • High tolerance to particulates, typically up to 150um
  • Low RSD's due to highly accurate construction
  • Slurry nebulizers have a natural liquid uptake of 6ml/min but operates best between 1.5 - 2.5ml/min

DuraMist w/ UniFit

 The DuraMist nebulizer is the most economical nebulizer for high-precision analyses involving samples digested in HF.  Recommended for samples containing up to 5% HF.

  • Material: HF-Resistant PEEK
  • High physical reproducibility ~ 2%
  • TDS tolerance, typically up to 30%
  • High tolerance to particulates, up to 75um (uptake-dependent)
  • Low RSD's due to concentric geometry
  • Uses only standard ICP argon supply pressures
  • Standard 6mm size fits standard cyclonic spray chambers. Adaptors are available for Scott type spray chambers
  • Standard available uptakes: 0.4 and 1.0ml/min

Glass Expansion PolyCon Nebulizers

The PolyCon concentric nebulizer is ideal for high precision analyses involving samples digested in HF. The PolyCon has also been used successfully in ICP desolvators such as the MCN-6000, where high temperatures are encountered. It has become a favorite in the semi conductor industry, and has enabled analysts to produce accurate (r = 0.9998) calibration curves for low-ppt levels of Na, K, Fe and Ca in 30% hydrogen peroxide.

  • Material: HF Resistant Polyimide
  • High physical reproducibility ~ 2%
  • High tolerance to particulates, up to 75um depending on uptake
  • TDS tolerance, typically ~5%
  • Low RSD's due to concentric geometry
  • Uses only standard ICP argon supply pressures
  • Standard 6mm size fits standard cyclonic spray chambers. Adaptors are available for Scott type spray chambers
  • Standard available uptakes: 0.05, 0.1, 0.2, 0.4, 0.6, 0.8, 2 & 5ml/min for samples with large particulates

OpalMist Nebulizers

The OpalMist PFA concentric nebulizer is the nebulizer of choice for high precision analyses requiring the highest chemical resistancy to HF, alkalis and organics. The high purity PFA construction makes it ideal for ultra-trace ICP-MS work.
