Capillary Transfer of Single Droplets


Transfer ring samples from one capillary to a second capillary is not straight forward. Even more so for small quantities such as droplets.

Technology Overview

Scientists of Leiden University have developed an apparatus for 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 (eg 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.
