NEW E-Torch™

Ultimate Plasma Stability. Years of Torch Life.

Now available for Thermo Scientific® PRO Series and Agilent® 5000 Series ICP-OES

For over 30 years, Glass Expansion has led the ICP industry in demountable torch design and pioneered ceramic torches to deliver robust plasma performance and simplified maintenance. The E-Torch™ extends that legacy to Thermo® PRO and Agilent® 5000 instruments, engineered with precision annular spacing and advanced materials to deliver stability and versatility across the widest range of sample types.

Why Labs Choose the E-Torch

Traditional quartz torches and open-loop designs struggle with high-TDS samples, organics, fusion digests, and wear-metal oils. This is due to plasma instability, rapid tube degradation, and frequent maintenance, which drives up cost and downtime.

The E-Torch was engineered to solve these problems directly: tighter control of annular spacing for stable dual-view performance, a hotter and more robust plasma when the ceramic plasma tube is used, and true injector interchangeability so one torch body can be optimized for virtually any sample type.

Key Features & Benefits

  • 30+ Years of Demountable Torch Innovation: Proven demountable torch technology, now available for Thermo® PRO and Agilent® 5000 ICP-OES systems. Built on over three decades of innovation, it delivers ease of use, robustness, flexibility, and reliability that have made Glass Expansion demountable torches the preferred choice for challenging sample matrices.
  • Hotter Plasma. Longer Life: The all-ceramic plasma tube generates a hotter, more robust plasma, reducing matrix effects while delivering measurable improvements in sensitivity. In aggressive sample matrices, ceramic plasma tubes can provide years of service, compared with the shorter time frames often achieved by conventional quartz torches.
  • Maximum Plasma Stability: Precision-controlled annular spacing improves analytical stability while extending torch life.
  • Higher Aerosol Transport Efficiency: Advanced tapered injector geometry promotes laminar gas flow around the tip, improving transport efficiency, short-term precision, sensitivity, and overall analytical performance.
  • Simplified Maintenance: User-friendly retainers ensure precise alignment between the injector and plasma tube and enable quick, repeatable assembly, reducing service time.
  • One Torch for Every Application: Fully interchangeable Quartz, Alumina, and Sapphire injectors, available in multiple internal diameters, provide exceptional flexibility for aqueous, organic, high-TDS, fusion, and wear-metal analyses.

Ceramic Plasma Tube: Years, Not Days

As the pioneer of ceramic torches, Glass Expansion introduces the all-new ceramic plasma tube. Ceramic torches produce a hotter, more robust plasma that reduces matrix effects and improves detection limits. Lifetime matters just as much: compared with quartz, the ceramic plasma tube lasts dramatically longer, cutting maintenance, cleaning, and downtime from torch failure. In some matrices, quartz tubes degrade within hours, in comparison ceramic tubes may last years under the same conditions. The Plasma Tube (ceramic or quartz) can also be placed in a drying oven or muffle furnace to speed up drying after cleaning or easily bake-off carbon buildup.

Ideal For:
  • High-TDS samples that quickly devitrify quartz tubes.
  • Analyses at the detection limit, as the hotter plasma condition increases sensitivity.
  • Monitoring wear metals in engine oils, where quartz tubes crack under thermal shock.
  • Fusion sample analysis, where lithium salts rapidly attack quartz.

Comparison of Quartz Plasma Tube to Ceramic Plasma Tube

Element % Increase in Sensitivity % RSD
Zn (213) λ 17% 0.37
Ni (231) λ 19% 0.57
Mn (257) λ 14% 0.52

Precision Annular Spacing

Traditional quartz torch manufacturing methods are limited in terms of tolerance for the annular spacing between the outer and intermediate tubes. This annular spacing affects gas flow rates and, in turn, the stability of the plasma and lifetime of the torch, which can be further compromised when analyzing complex matrices. Therefore, it is important to maintain a precise annular spacing to achieve optimal and reproducible results and maximize the operational life of the torch. Glass Expansion’s proprietary manufacturing capabilities enable superior control of annular spacing. Maximum stability delivers the best precision and lowest detection limits.

Tapered Injector Technology

Glass Expansion's advanced tapered injector geometry promotes laminar gas flow around the tip, improving aerosol transport efficiency, short-term analytical precision, and sensitivity compared with traditional designs.

Tapered Bore Injectors
More efficient aerosol transport and improved sensitivity.
Capillary Bore Injectors
Straight bore ID, typically 0.5–2.5 mm.

Injector Selection Guide

Glass Expansion uses raw materials of the highest purity, helping improve detection limits by keeping background contamination as low as possible. Use the tables below to find the right diameter and material for your matrix.

Choose by Sample Matrix

Bore Size ID Range Best For
Narrow Bore ~0.8–1.0 mm Volatile organic solvents (ketones, alcohols, aldehydes), smaller ID reduces plasma solvent load to stabilize it
Standard Bore ~1.5–2.0 mm (down to 1.2 mm) Routine aqueous matrices; also suitable for semi-volatile analyses
Large Bore ~2.0–3.0 mm High-TDS matrices, large bore prevents blockages from salt deposit build-up near the tip

Choose by Injector Material

Material Best For Watch Out For
Quartz Routine aqueous and volatile organic analyses. Most cost-effective Not compatible with HF at any concentration; shorter lifetime; tip can chip easily
Alumina (Ceramic) High temperatures, high TDS, acid resistance, including HF, mineral acids, and aqua regia; also less-volatile organics like xylene Higher cost than quartz
Sapphire Low-background applications involving silicon, boron, and HF Premium cost; reserved for high-purity work
