MUF HPLC-Chip design. The MUF HPLC-chip is a variation on standard HPLC-chips.35 An additional laser ablated channel runs from a previously unused inlet port and joins its flow to the analytical column effluent before the electrosprayer. The chips utilized for this work have a 500-nL trapping column.
