Disclosed herein include systems, apparatuses, devices, and methods for introducing one or more components into a fluid. A first fluid and a second fluid can be co-injected into a fluidic channel of a flow cell. In some embodiments, the first fluid and a second fluid are immiscible (e.g. an aqueous buffer and a non-aqueous liquid). In some embodiments, the second fluid is less dense than the first fluid. |
