Workflow Efficiencies: 2D Liquid Chromatography and Novel Sample Preparation Techniques

Workflow efficiency can be realized through 2D liquid chromatography techniques and associated novel sample preparation approaches. Learners will receive guidance on 2D hardware parameters and gain insight and implementable tools covering novel micro extraction process and disruptive concepts such as: elimination of evaporation & reconstitution steps, high volume injection, and analysis of clean organic extracts. Attendees will leave this day-long course with cost and time saving measures that can be immediately applied to their own lab protocols.

Information

The concept of multi-dimension chromatography with AT-column dilution offers the option of large volume injection and clean organic extracts. These new hardware capabilities bring options in developing cost effective sample preparation protocols. The enrichment requirement for trace analysis is no longer a requirement within a sample preparation protocol, and can now be shared with the 2D LC solution by using large volume injection (up to 1000 uL). This then allows exploration of micro extraction protocols that convert day-long extraction process to less than one hour. As an added bonus, the 2D LC with AT-column dilution also brings a disruptive contribution that bolsters efficiency. With the added dilution, clean organic extracts can also be considered for analysis. This eliminates the time consuming evaporation and reconstitution steps within the extraction protocols created for 1D chromatography.
