Abstract
A sample load and injection device (10) includes sample introduction capillaries (11) attached to a microfluidic device (12). Sample introduction capillaries (11) are connected to sample introduction channels (18). Sample introduction capillaries (18) are connected to separation channels (20) at connection points (21). At a defined distance along the separation channels (20), auxilliary channels (23) originate at connection points (24). The sample load and injection device includes cover plate (28) which has connecting channels (26, 32). Connecting channel (26) is associated with ends (24) of sample introduction channels (18). Connecting channel (32) is associated with ends (20).
