In-line addition of internal standards and ionization buffers provides an efficient means of accurately and precisely dosing all of your samples without extra effort or the risk of error or contamination. Internal standardization (IS) is often used to compensate for physical and mass-space interferences in ICP spectrometry. It can also enhance short-term and long-term reproducibility.

The Trident CT™ from Glass Expansion is the simple, easy and error-free way to continuously add internal standards or ionization buffers in ICP spectrometry.

The Trident CT™ mixing chamber uses ConstantTorque™ (CT) technology to provide a simple to use, leak-free connection for both the internal standard and sample, every time.

The Trident CT features:


Durable, Repeatable, Leak-Free ConstantTorque™ Connections

The use of inert, metal-free, CT ratchet fittings on the inlet and outlet of the Trident mixing chamber provides simple-to-use, leak-free connections for the internal standard and sample, every time. With other mixing chambers, worn or improperly fitted connections leak, injecting a stream of air bubbles into the nebulizer flow, which degrades short-term analytical precision (%RSD). By using CT ratchet-style fittings, the Trident CT eliminates air leaks, optimizing analytical performance.

Customer comments

We currently use GE IsoMist and Trident internal standard in line reagent addition kit we love it and its a great piece of kit!

I've been using a Trident for 4 years now, and its been working very well.

I used an older version of the PE Online Internal Standard Addition kit for many years. ... I have found a similar kit offered by Glass Expansion to be a great improvement over the old PE kit. It has a glass T with friction-fit connections that are the same as the GE quick connect nebulizer fittings. They also provide flared-end peristaltic pump tubing that eliminates the problems you run into when trying to connect the narrow bore tubing.
