SeaSpray™ DC Nebulizer
The high dissolved solids nebulizer
The SeaSpray™ concentric DC nebulizer offers outstanding nebulization efficiency for trace level analyses. It offers freedom from clogging while nebulizing solutions to the limit of solubility of most mineral salts, and conferring significant sensitivity gains. The SeaSpray™ concentric DC nebulizer has the the highest sensitivity for any concentric nebulizer on the market.
Product Features
Simply the Best!
The SeaSpray ™ nebulizer has re-written the rules for analysis with ICP-OES and ICP-MS – providing improved precision and sensitivity as well as freedom from clogging while nebulizing up to 20% salt solutions.
The SeaSpray combines a unique self-washing tip with the revolutionary Glass Expansion VitriCone construction. The SeaSpray nebulizer tip has been carefully designed with smooth surfaces to minimize the adhesion of salt crystals. The design also uses the washing action of the dispersing droplets to further prevent crystal growth, allowing the SeaSpray to handle up to 20% salt solutions.
With some concentric glass nebulizer brands, the sample channel is constructed from fine drawn out capillary tubing. Glass Expansion nebulizers, on the other hand, use the unique VitriCone construction. With the VitriCone design, the sample channel is constructed from heavy glass capillary which is machined to very tight tolerances.
- The sample channel is uniform, so salt deposition is inhibited.
- The industry’s tightest tolerances ensure that each nebulizer will perform to the same high standards as the previous one.
With the SeaSpray U-Series and DC nebulizer, our proprietary UniFit connector slides easily over the sample arm and creates an excellent seal. As with all U-Series and DC nebulizers, the sample channel is uniform from the entry point to the tip so there is nowhere for particulates to be trapped. Since there is nowhere for the sample to be trapped, you get the fastest possible washout and highest sample throughput. We supply SeaSpray U-Series and DC nebulizers for all ICP-OES and ICP-MS spectrometers.
MicroMist™ DC Nebulizer

Glass Expansion's MicroMist™ Direct Connect (DC) nebulizer is ideal for low-flow applications due to its excellent transport efficiency and precision. Backed by industry's tightest tolerances, precision manufacturing, and the proprietary VitriCone™ capillary have driven the MicroMist DC nebulizer to be the worldwide standard nebulizer for low-flow ICP-OES and ICP-MS applications.
Product Features

- Reliable ratchet fitting ensures leak-free nebulizer gas connection.
- Instrument-specific Direct Connect flexible argon gas line (click here for the DC video installation guide).
Performance
Although the MicroMist nebulizer operates a at lower sample flow rate, the transport efficiency is significantly higher compared to a standard concentric nebulizer. The graph illustrates the relationship between uptake rate and nebulizer efficiency (the percentage of the sample that reaches the plasma as opposed to going down the drain).
At 50 µL/min the MicroMist has a 50% efficiency and therefore injects 25 µL/min into the plasma. On the other hand, a standard 2 mL/min concentric nebulizer has a 2% efficiency, resulting in 40 µL/min of sample injected into the plasma. This means that the MicroMist nebulizer can reduce sample consumption by a factor of 40 and yet the sensitivity is reduced by less than a factor of two. For this reason, the MicroMist is first choice for applications with limited sample volumes.
With a strong and consistent self-aspiration, the MicroMist nebulizers can be used with or without a peristaltic pump. The MicroMist product line includes models with natural sample uptake rates of 50, 100, 200, 400 and 600 µL/min. When choosing a MicroMist nebulizer, select the model that most closely matches your desired sample flow rate. It is always OK to starve a nebulizer, but you should not exceed the natural sample uptake rate.
The smaller droplet size of the MicroMist nebulizer has additional analytical advantages, including reduced matrix interferences and a more robust plasma.
Although the MicroMist nebulizer is a low-flow nebulizer, it still provides a relatively high tolerance to total dissolved solids (TDS) at 15%. Providing the ability to handle a wide range of sample types, including challenging samples such as waste water, soil, blood, serum, and urine. For the enhanced tolerance to TDS consider adding an argon humidifier, such as our Elegra.
- Any ICP-OES and ICP-MS application demanding the highest transport efficiency and precision.
- Samples with limited volume, such as biological samples.
- Samples of high value, such as precious metals and fine chemicals.
- Hazardous or radioactive that are difficult to dispose of.
- Any organics and highly volatile organics that are challenging due to plasma instability.
- Isotope ratio and single event ICP-MS (single-cell, single particle, and nanoparticle) analysis where precision and efficiency are critical. Applications requiring the highest sensitivity and precision, such as toxic metals in cannabis.
