The innovation design of miniaturization of chromatographic instruments, in combination with the progress in materials and opto-electron technologies, has led to the breakthrough in key chromatography techniques. The novel design of detectors has improved the sensitivity and reduced the consumptions of power and gases. The utilization of surface thermo ionization principle yields a detector of extremely high sensitivity and selectivity towards amines. The low cost, high performance integration and miniaturization of chromatograph will lead to high standard commercial instruments in the two or three coming years. These instru- ments will be applied for on-line or off-line monitoring in fields and laboratories. Important progresses on the developments of detectors and miniaturization of instruments are reviewed and commented in this paper.
