Capillary Transfer of Single Droplets
Transferring samples from one capillary to a second capillary is not straightforward. Even more so for small quantities such as droplets.
Scientists of Leiden University have developed an apparatus to transfer droplets from a first capillary to a second capillary (Figure 1).
For sample handling and sample pre-treatment, the sample is flowing through small tubes in many applications. At Leiden University, scientists had concentrated a sample in a droplet at the end of a capillary (Anal. Chem., 2013, 85 (12), pp 5734–5739). This droplet needed to be transferred to a second capillary for further handling of the droplet (e.g. transportation to NMR).
Details and State of Development:
- Proof of concept has been established with the working set-up in our lab
1. LC - NMR
2. LC - EV - NMR
3. LC - SPE - NMR
Leiden University is seeking commercial partners to (co)develop this into commercial products. Applications can be very broad, Leiden University has concentrated its efforts towards sample handling for LC-NMR.
