Abstract: A progressive cellular architectures has been presented for vapor-phase chemical analyzers. The progressive cellular architecture consists of a series of heterogeneous micro-gas chromatography cells. Each individual cell targets vapor species within a specific volatility range by using a unique combination of a preconcentrator and a separation column. The cells are connected progressively in series to cover a broad range of volatile analyte chemical vapors. Valves may inadvertently absorb or adsorb and subsequently release target chemical analyte molecules, thereby interfering with quantitative analysis. Therefore, the inlet to the cells is configured without a valve.
