New Products for the PerkinElmer ® NexION 1000/2000 ICP-MS

Glass Expansion has 4 decades of experience manufacturing sample introduction components for ICP-MS and has earned a world-wide reputation for quality and reliability. Continuing this tradition, we are pleased to add the release of the D-Torch, the Helix Cyclonic Spray chamber and the Single Cell Sample introduction to the NexION 1000/2000 Product range.

A Robust, High Performance Demountable ICP Super Torch.

Figure 1. Exploded View of D-Torch

D-Torch

An Inductively Coupled Plasma (ICP) torch can be a costly consumable item requiring regular maintenance and replacement, particularly with aggressive sample matrices, such as hydrofluoric acid (HF), organic solvents and high total dissolved solids (TDS).

The patented D-Torch is a revolutionary demountable torch design from Glass Expansion. The D-Torch uses high precision engineering to provide the benefits of a fully demountable torch, such as lower running costs, chemical inertness and configurable injector geometry without compromising usability, performance or durability. Compared to other conventional torches, the D-Torch offers:

  • Better analytical precision with the unique tapered injector design
  • A choice of quartz, alumina and sapphire injectors in a range of diameters for aqueous, organic, high salt, fusions or HF containing samples
  • Lower running costs as only the outer tube is replaced when it wears
  • Easier cleaning and maintenance with the ability to remove the injector and outer tube and no O-rings to degrade and go brittle
  • The patented D-Torch is a revolutionary demountable super torch, which only requires you to replace the components that are warn.

Helix CT (ConstantTorque) Spray Chamber

Figure 2. Helix CT (ConstantTorque) Spray Chamber

Spray Chamber

The spray chamber is a crucial component of the ICP sample introduction system since it has a profound effect on transport efficiency, precision, and washout. Glass Expansion revolutionized spray chamber design with the Tracey and Twister single-pass and double-pass cyclonic spray chambers, providing improved transport efficiency and reduced washout. Glass Expansion's unique Helix CT nebulizer interface features an inert PTFE seal to eliminate dead-volume giving quicker washout and higher sample throughput.

The Glass Expansion cyclonic spray chambers for the NexION ICP-MS have a:

  • Double-pass Twister™ version with central baffle that rejects large droplets from the nebulizer aerosol for best short-term precision and lowest interferences
  • Single-pass Tracey™ version for the highest sensitivity
  • Vertical wall design that improves transport efficiency and short-term precision by ensuring smooth drainage of excess sample
  • Positive stop on the Helix CT nebulizer interface ensures consistent nebulizer positioning in the spray chamber for reproducible long-term analytical performance
  • Side-wall groove that improves drainage and prevents sample re-nebulization
  • Inert PTFE seal (no oring's) that cannot stick to the nebulizer and is easier to clean
  • Low volume (20mL) options available for high sample throughput

High Efficiency Sample Introduction System (HE-SIS)

Figure 3. HE-SIS Diagram

Single-cell analysis by ICP-MS (SC-ICP-MS) is enhancing the basic understandings in cellular biology, oncology and drug discovery. SC-ICP-MS allows quantification of metals in individual biological cells at ultra-low detection levels not previously seen in other techniques. SC-ICP-MS can be used to study disease aetiology, provide a better understanding of diseased cell states and develop new drug treatments for better patient outcomes.

The Glass Expansion High Efficiency Sample Introduction System features:

  • An on-axis, high efficiency laminar flow spray chamber
  • A MicroJet Make-up gas adapter that provides high velocity sheathing gas that entrains and shapes the nebulizer aerosol plume to prevent cell deposition on the spray chamber walls
  • High efficiency, low uptake, concentric glass nebulizer designed to efficiently nebulize single-cell suspensions without compromising cell integrity
