seaFAST – Automated Preconcentration System for Undiluted Seawater
The seaFAST is an automated sample introduction system for analysis of seawater and other high matrix samples. It delivers excellent accuracy and repeatability, giving labs research-quality results with minimal effort.
Performance
- Best detection limits of any system on the market
- Inline or offline, automated preconcentration and matrix removal
- Ultraclean, enclosed reagent flow path for ultra-low blanks
- Completely syringe-driven reagents for consistent chemistry and maximum cleanliness
- Hydride generation for improved detection limits for As, Se, Hg, and other hydride-forming elements (some models)
seaFAST Model Comparisons
seaFAST SP3
The seaFAST SP3 offers three modes of operation for inline seawater analysis, as well as offline preconcentration mode. The seaFAST SP3 also features prepFAST autocalibration and autodilution features, eliminating the need for manual preparation of calibration standards, and optional automatic matrix matching for the best accuracy in high matrix samples.
Preconcentration mode:
Undiluted sample is loaded onto a chelation column, where many elements are chelated and the matrix is removed. The chelated elements are eluted directly into the nebulizer. Preconcentration mode dramatically improves detection limits by eliminating matrix effects and increasing sensitivity.
Direct mode:
Undiluted sample is automatically diluted inline and measured directly. Direct mode is acquired while the sample is being loaded onto the preconcentration column, so it does not increase the analysis time.
Hydride mode:
Volatile hydrides of As, Se, and other hydride-forming elements are generated and introduced directly into the spray chamber, dramatically increasing sensitivity for these elements. Hg may be determined simultaneously via cold vapor using the same reagents.
Since the seaFAST performs all modes automatically, procedural blanks associated with manual offline sample preparation are eliminated. The seaFAST SP3 offers complete flexibility and can run in Preconcentration, Direct, Hydride, or any combination of modes by simply selecting the desired mode(s) in the software.

seaFAST SP2
The seaFAST SP2 offers two modes of operation for inline seawater analysis, as well as offline preconcentration mode. The seaFAST SP2 also features prepFAST autocalibration and autodilution features, eliminating the need for manual preparation of calibration standards, and optional automatic matrix matching for the best accuracy in high matrix samples.
Preconcentration mode:
Undiluted sample is loaded onto a chelation column, where many elements are chelated and the matrix is removed. The chelated elements are eluted directly into the nebulizer. Preconcentration mode dramatically improves detection limits by eliminating matrix effects and increasing sensitivity.
Direct mode:
Undiluted sample is automatically diluted inline and measured directly. Direct mode is acquired while the sample is being loaded onto the preconcentration column, so it does not increase the analysis time.
Since the seaFAST performs all modes automatically, procedural blanks associated with manual offline sample preparation are eliminated. The seaFAST SP2 offers complete flexibility and can run in Preconcentration, Direct, or both modes by simply selecting the desired mode(s) in the software.

seaFAST S2
The seaFAST S2 offers two modes of operation for inline seawater analysis as well as offline preconcentration mode:
Preconcentration mode:
Undiluted sample is loaded onto a chelation column, where many elements are chelated and the matrix is removed. The chelated elements are eluted directly into the nebulizer or an offline destination vial. Preconcentration mode dramatically improves detection limits by eliminating matrix effects and increasing sensitivity.
Direct mode:
Undiluted sample is automatically diluted inline and measured directly. Direct mode is acquired while the sample is being loaded onto the preconcentration column, so it does not increase the analysis time.
Both Preconcentration and Direct modes reduce procedural blanks associated with manual offline sample preparation. The seaFAST S2 offers complete flexibility and can run in Direct, Preconcentration, or both modes by simply selecting the desired mode(s) in the software.
Offline mode:
Samples are preconcentrated onto a chelation column, and the chelated elements are eluted with clean acid into a vial or microplate on the autosampler for later analysis by ICPMS. Users can easily configure the preconcentrated volume in 10 mL increments and customize the final elution volume.

seaFAST Litre
The seaFAST Litre high-volume automated preconcentration system is designed to preconcentrate large volumes of seawater for ultratrace determination of elemental concentrations and isotope ratios. Bottles with high-volume samples up to 2 L each may be connected directly to the ultrapure valve system for contamination-free preconcentration and matrix removal. Smaller samples, standards, or blanks for routine analysis may be placed on the autosampler for direct sampling and preconcentration.
The seaFAST Litre offers two modes of operation for inline seawater analysis as well as offline preconcentration mode:
Preconcentration mode:
Undiluted sample is loaded onto a chelation column, where many elements are chelated and the matrix is removed. The chelated elements are eluted directly into the nebulizer. Preconcentration mode dramatically improves detection limits by eliminating matrix effects and increasing sensitivity.
Direct mode:

Offline mode:
Samples are preconcentrated onto a chelation column, and the chelated elements are eluted with clean acid into a vial or microplate on the autosampler for later analysis by ICPMS. Users can easily configure the preconcentrated sample volume from 10 mL to >2 L.
