| Popis: |
In this paper we report an improvement by an order of magnitude of the detection limit of micro gas chromatography systems through the use of m-sequence stochastic injection patterns. Using a sequence length of 127 and using a concentration level of 10 ppb for a BTEX mixture, we obtained an improvement by a factor of 9 in SNR, almost at the theoretical limit of 11 (~√(127)). We also successfully demonstrate that it is possible to simultaneously analyze multiple samples streams in parallel using a single micro-column and the proposed injection technique. |
