SampleSense is the only sample introduction valve on the market with optical sensor technology. It is a fully automated sampling valve for ICP and ICPMS, featuring Intelligent Sample Verification (ISV). The valve automatically detects and injects the sample and then triggers the analysis. This technology is available for Elemental Scientific’s FAST and prepFAST systems. It further increases instrument productivity and fully automates the sample uptake process.
SampleSense for SC-FAST and prepFAST Systems
The SampleSense valve operates with ESI autosamplers equipped with both FAST and prepFAST technologies. The fully automated SampleSense operation with FAST is shown in the schematics below; operation with prepFAST systems follows the same process.
SampleSense’s ISV technology provides positive confirmation that the samples loaded properly. SampleSense sends loading error reports directly to the instrument software when the following conditions occur:
Sample loading speed is impacted by the viscosity of a given sample. High viscosity samples require additional time for the sample to be transported from the autosampler probe to the sample loop while low viscosity samples require less time. SampleSense automatically detects the arrival of the sample at the valve, eliminating the need to determine the required sample loading time for each sample matrix analyzed. In the experiment below a highly viscous sample (concentrated sulfuric acid) was automatically loaded into a prepFAST system equipped with SampleSense.
Samples of limited volume must frequently be introduced for analysis. SampleSense supports these small volume samples with ISV technology by minimizing sample consumption during the sample loading process. Once the sample loop is fully loaded, the sample injection and analysis are triggered automatically. Shown below is an example of FAST with SampleSense utilized to load and inject small sample volumes into an ICP system.
