Features of the DuraMist Nebulizer

Glass Expansion's DuraMist™ DC Nebulizer is one of our most versatile and durable concentric nebulizer designs. Manufactured with a PEEK body and PTFE capillary insert, the DuraMist can handle the toughest acid matrices, including up to 5% Hydrofluoric Acid (HF). A uniquely designed smooth tip, provides an outstanding tolerance to total dissolved solids (TDS), up to 30%. Manufactured under the most critical specifications, the DuraMist DC delivers superior sensitivity and precision at a cost-effective price.

Available in a 2.0, 1.0 and 0.4 mL/min model, providing a stable self-aspirating sample uptake or can be used in conjunction with your instrument's peristaltic pump or syringe pump for sample delivery. The direct connect installation seamlessly integrates the DuraMist DC nebulizer as a universal nebulizer for all ICP-OES and ICP-MS models.

Product Features

Exceptional tolerance to total dissolved solids (TDS):

A smooth nebulizer tip prevents salt accumulation, which allows for enhanced signal stability and the highest TDS tolerance (up to 30%) of all our concentric nebulizer designs.

High chemical resistivity:

Manufactured with a PEEK body and PTFE capillary insert provides excellent compatibility with solvents and acids, including up to 5% HF.

High sensitivity and precision:

The rigidity of the PEEK body allows for manufacturing with high physical reproducibility, resulting in an inert concentric nebulizer design that does not compromise sensitivity and precision for demanding ICP-OES and ICP-MS applications. A comparison of the DuraMist DC with the SeaSpray DC, our worldwide market-leading high performance glass nebulizer, showed that the DuraMist DC gave similar performance.

Durability:

In addition to being inert, the rigid PEEK body provides a more durable option compared to PFA nebulizers that are prone to deform over time.

Compatibility:

Available in a 2.0, 1.0 and 0.4 mL/min model, and a direct connection installation, the DuraMist DC nebulizer seamlessly integrates with all ICP-OES and ICP-MS models.

The following table compares the average intensity and RSD, over a range of elements, for the SeaSpray and DuraMist.

	Intensity %	RSD %
SeaSpray	100	0.23
DuraMist	87	0.28

* The DuraMist nebulizer is recommended for samples containing up to 5% HF. For samples with higher concentrations of HF, we recommend the OpalMist PFA nebulizer.

Direct Connection (DC) Nebulizer

The DC nebulizer has a UniFit sample connector that slides easily over the sample arm and an argon gas connector configured to connect directly to your ICP. The benefits of the DC nebulizer are:

Inert metal-free argon gas connector.
Instrument-specific Direct Connect flexible argon gas line.
Reliable ratchet fitting ensures leak-free argon gas connection.

DC versions of the SeaSpray, MicroMist, Conikal, Slurry, DuraMist, OpalMist, and VeeSpray nebulizers are available to suit the most common models of ICP-OES and ICP-MS.

The DC nebulizer part number has a prefix specific to each type of gas connector. For example, the prefix "A13-" denotes a connector for the Agilent ® 5100/5110/5800/5900 ICP-OES, so part number A13-07-USS2 is a SeaSpray nebulizer configured for direct connection to the Agilent ® 5100/5110/5800/5900.

Nebulizer Maintenance Made Easy

If the sample capillary becomes blocked with particulates, use the Eluo Nebulizer Cleaning Tool to remove the blockage. For the DuraMist and OpalMist nebulizers, use the Eluo OPD version (P/N 70-ELUO-OPD). Regular use of the Eluo will help keep your nebulizer clean and in good condition.

If blockages due to particulates are a frequent issue for your laboratory, consider adding the re-useable Guardian in-line filter (P/N 70-803-1108). The Guardian in-line filter provides a simple and effective way to eliminate the risk of a blockage. And the filter can be cleaned using a simple attachment for the Eluo (P/N 70-803-1160).

To keep your DuraMist nebulizer in optimum condition, follow our detailed nebulizer maintenance procedures listed in our Nebulizer Maintenance flyer.

Customer Comments

We are doing good with it. We have HF in our solutions, and it has worked good for us with that. We digest metal powder into solution and that is what we analyze through the nebulizer - we have several and keep them in rotation and have started rotating them through the refurbishment process.

I've only had the neb on for a few days, but so far it looks great. Precision appears tight - and I'm intrigued about the ease of backflush with the tool and adaptor. I'll continue using the DuraMist, and if all remains well, I'll recommend it to other locations.

I made the change to DuraMist and GEICP when I first started working here. I have used GEICP products for many years prior to working here. I have always been impressed with the quality and competitive pricing of GEICP products. Regarding DuraMist nebulizers, we find them to be more robust than competitors nebs, and your refurbishment program saves us several hundred dollars annually.

Phosphate and specialty fertilizer company - USA

Thank you for your great products! Every day when I run the Arcos with the TFE spray chamber, the ceramic D-torch and Duramist nebulizer, I say Thanks, GE!

Chemical supplier - USA

I am happy to tell you I am very satisfied with the GE products, I've been using your nebulizers for more than 10 years now.

Geochemistry laboratory - USA

First off, I would like to say thank you for supplying us with a quality product and backing it with a great service. I have been with this company for 12 years now, still using the same Thermo Scientific™ iCAP 6300 ICP-OES system. We started using the DuraMist nebulizer since 2013 coupled with your HF spray chamber. Our lab receives a wide range of sample types which requires us to use a number of different acids, peroxides, and bases for our sample prep. The DuraMist line of nebulizers gives us the flexibility to run samples with high matrix and TDS in solution and still manage to see great sensitivities for some elements down to sub ppm. Along with general care and the Eluo HF cleaner, we have managed to throw a lot of volume through these nebulizers and cut back on down time. Having the ability to run NaOH complexed solution before trace level precious metal run with minimum wash out with just dilute nitric is another reason you can't go wrong with these nebulizers.

I am happy to tell you I am very satisfied with the GE products, I’ve been using your nebulizers for more than 10 years now.

Geochemistry laboratory - Netherlands

The new DC neb is even better than I reported...The signal gain was actually more than 20% (!!). I was measuring Pb isotopes when I observed signal loss on the old neb (started at 9.7V, typical signal strength, and then went down to 9.1V) and instead of rinsing the neb I replaced it with the new DC type and the signal went up to 11.9V.

University laboratory - USA

The Duramist Nebulizer performs very well. The Si background is as low as they have ever seen, and the stability of the DuraMist has proven excellent.
