Glass Expansion offers two In-line Reagent Additions kits, one which includes a glass mixing chamber/combiner for solutions which do not contain HF and another which includes an inert mixing chamber/combiner. Both kits are completely modular so that damaged or worn components can easily be replaced. We have even designed a line of Flared-end pump tubing to supplement the modularity of the kit.
The heart of the kit is the mixing chamber/combiner. It is designed for zero dead volume on the input ends which accommodate the sample and addition lines. The output end, however, is designed with a small mixing chamber so that the sample and added reagent are intimately mixed prior to introduction to the nebulizer. All connections to the mixing chamber/combiner use our tried and tested EzyFit connectors. A sampling probe for the reagent addition bottle is included so that it remains well anchored in the bottle.
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. In many cases, it also enhances short-term and long-term reproducibility.

The peristaltic pump tubing is not supplied as part of the Internal Standard Kit but can be ordered separately.
We recommend Flared-end Peristaltic Pump Tubing.
We currently use GE IsoMist and Trident internal standard in line reagent addition kit – we love it and it’s 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.
