Tutorial Method
This basic method provides the core methodology for translating a workflow into OneLab-executable script(s) as an attempt to fully or semi-automate a specific procedure. It demonstrates the benefits of automation and highlights OneLab capabilities and best practices to promote solution adoption, helping transition from manual to a more automated approach. It can be used alone or serves as a building block for a more complex workflow and is easily adaptable to users' requirements.

This work demonstrates the capabilities of the Andrew+ Pipetting Robot configured with the Extraction+ Connected Device for fully automated SPE sample preparation using cartridge and plate formats. Described Protocols use a simple 3-step SPE procedure (load, wash, and elution) in combination with Waters reversed-phase Oasis HLB cartridges (1, 3, and 6 cc size) and 96-well macro and μElution plates.

Dilute-and-shoot is a simple and rapid analytical method for multi-analyte identification. Although sample preparation is minimal, it remains a critical step to ensure accurate quantitation. The protocols described here use the dilute-and-shoot approach and take advantage of the Andrew+ capabilities to automate sample preparation ensuring maximum pipetting precision and efficient mixing.

Mixed-mode SPE is a sample clean-up technique for LC-MS analysis. Selecting a mixed-mode SPE sorbent can be challenging, requiring a good understanding of the sorbent/analyte chemistry. In addition, it involves accurate and precise pipetting steps. This protocol demonstrates a rapid and robust Andrew+ automated mixed-mode SPE sorbent selection method using the Oasis 2x4 sorbent selection plate.

Protein precipitation is the simplest form of plasma/serum preparation. However, pipetting errors and contamination during sample preparation can impair assay sensitivity, robustness, and precision. In the following work, Andrew+ was used to prepare and extract analytes from complex biological matrices, using the Ostro sample prep plate, with subsequent LC-MS/MS analysis and quantification.

Therapeutic and endogenous peptides can be difficult to extract using SPE with high reproducibility. This is often due to user errors encountered during the extraction process. Here we present an extraction protocol for peptides using the Andrew+ robot which demonstrates rapid and robust automated mixed-mode SPE sorbent selection using the Oasis Peptide Method Development 96 well μElution Plate.
