Megjegyzések:	This study describes the direct interfacing of polydimethylsiloxane (PDMS) microfluidic chips with laser-inducedbreakdown spectroscopy (LIBS) detection. The changes induced in the PDMS material by nanosecond laser abla-tion are briefly documented by using optical microscopy and scanning profilometry. The main part of the studyfocuses on the solution of technical and analytical problems of coupling single-pulse LIBS detection with PDMSmicrofluidic chips in order to assess the feasibility and performance of the concept of creating a lab-on-a-chip de-vice with LIBS detection (LOC-LIBS). Multiple optical and sample presentation schemes including in-channel andin-port detection were tested, but it was found that LOC-LIBS is only viable and practical with in-port detectionoutside the chip. It was shown that LOC-LIBS in this configuration is capable of the trace speciation analysis ofchromium using as little as 0.5?L solution volume. The achieved absolute limit of detection was 2 ng.
