Sample Loading

Ninety-six discreet flow paths are formed by the Harvex to insure there is no cross contamination. Vacuum is applied to the top of the card to draw reagents through the card. Simply change the reservoir or microtiter plate on the sample loading tray to activate, load sample, and wash the cards. Samples can be loaded from microtiter plates or test tubes in the 96 well format. No dry-down or reconstitution steps are required. Complete preparation of a 96 well card can be performed in less than 5 minutes.

Sample Elution

Empore® cards are eluted directly to the detector (Mass Spec, UV...) using the Elutrix. Each zone is individually sealed, and a switching valve is activated to pass the mobile phase through the elution zone. The 96 zones on the card can be processed using four pre-programmed patterns, or in any order chosen by the customer utilizing up to 25 custom patterns. The Elutrix and the detector are synchronized via hardware signals to ensure accurate timing when processing the sample. The system is designed for running single cards or unattended operation with as many as thirty cards using the stacking cassettes.

Overall Benefit

Get vital test results quickly and utilize your valuable Mass Spec more efficiently! Utilizing a direct inject method at 2mL/min each data point can be analyzed in less than 40 seconds. This allows a complete 96 well card to be processed in about one hour. Cassette stackers allow unattended operation with the potential to process over 1,000 elution zones during an unattended twelve hour overnight run. The system can be fitted with a column to enhance peak shape, analyte separation, and signal-to-noise ratio.

The system provides simple sample loading and direct elution to your detection device with no intermediary steps plus simplified data processing. The SPExpress system offers your laboratory the efficiency and flexibility to keep pace with today's myriad of protocols by combining quick method development and prompt analysis in a stable, easy to use platform. The result is the most economical and efficient extraction/elution platform available today.
