SPEVA is designed to integrate solid phase extraction and nitrogen evaporation processes. It automatically completes the steps of conditioning, sample loading, rinsing, drying and elution, while continuously evaporating and solvent replacement of the eluent and then passing through the cartridge again. No human intervention is required during operation, freeing laboratory personnel and safeguarding their health. SPEVA offers multiple sample processing modes, making it suitable for various fields of sample pre-treatment such as pesticide residues detection in food, organic pollutant enrichment in large volume water samples from the environment, and toxic substance detection in viscous samples like blood and urine. With innovative and compact structure design of pump and valve, SPEVA exhibits the features of high throughput and efficiency with accurate results, significantly improving the detection capabilities of laboratories.
