We understand that dealing with aggressive sample matrices is a challenge and most real-world samples analyzed by ICP laboratories contain considerable concentrations of TDS, including soils, sludges, wastewater, brines, high acid digests, and fusions. Analyzing these types of samples can pose a number of challenges for the ICP analyst, including increased frequency of torch replacement due to shortened torch life.
The combination of high plasma temperatures and salt deposits on the torch leads to the devitrification of quartz torch outer tubes. The drawback of the single-piece torch is that it is a relatively expensive consumable item, requiring the replacement of the entire torch when, in most cases, only the outer tube is affected by devitrification.
The D-Torch to suit the Agilent® 5000 series ICP-OES (Figure 1), provides a robust and high-performing alternative to both the single-piece and semi-demountable quartz torches, ensuring greater robustness and a lower cost of ownership (Figure 2).

Compared to other demountable torches, the D-Torch is the only torch design that comes standard with a ceramic intermediate tube (Figure 3) for greater robustness and a lower cost of ownership. With demountable torch designs offered by other manufacturers, the intermediate tube is made of quartz and fused to the quartz outer tube, which is an additional consumable whose cost can quickly add up and negate the economic benefits of the torch itself.
Another exclusivity of the Glass Expansion D-Torch is an optional ceramic outer tube. For over 25 years, Glass Expansion has been the leader in ceramic torch design, offering ceramic versions of our acclaimed D-Torch for numerous ICP models. Compared to quartz outer tubes, the ceramic alternative has an extended lifespan, significantly reducing maintenance, cleaning, and downtime caused by torch failure. Incorporating a ceramic outer tube into your ICP torch has a range of benefits, particularly for the analysis of high-TDS sample matrices. The quartz torch in Figure 3 was run for only 6 hours with samples containing 10% NaCl and badly degraded. By contrast, the ceramic outer tube is not affected by salt deposits. (Figure 4).
In certain sample matrices, where quartz outer tubes degrade within hours, the ceramic outer tube perseveres for years under identical conditions, ensuring long-term reliability and cost savings.
In addition to providing durability, the ceramic outer tube on an ICP torch produces a hotter, more robust plasma, which reduces matrix effects and improves sensitivities and detection limits, compared to a quartz torch. Table I shows the average signal intensity, based on three separate measurements of 10 replicates using a 100 ppb multi-element standard. The overall average increase in signal intensity with the ceramic outer tube was 21%.
The Glass Expansion D-Torch design is a direct replacement for the standard Agilent® 5000 series torch, providing the same self-aligning, turn-key installation. The D-Torch also offers easier cleaning and maintenance with the ability to fully remove the injector and outer tube, with no o-rings which can quickly degrade and become brittle.
As a means to further assist your laboratory, we have organized this assembly guide video.
We are confident that the D-Torch will revolutionize your ICP spectrometry experience, enabling you to overcome the obstacles presented by aggressive sample matrices. Say goodbye to frequent torch replacements and excessive costs, and embrace the efficiency and reliability of the D-Torch.
