Search for: [Description = "A portable gas chromatograph with integrated micromachined flushed injector and thermal mass detector \(TCD\) has been developed. The silicon\/glass injector operatesin a fixed volume \(2_7 µL\) or electronically operated mode. An integrated, pneumatically operated, fast cross\-valve is applied in the injector. The TCD detector consists of two Pt microheaters and thermoresistors packaged in a silicon\/glassmicromachined chip. The temperature of two capillary molecular sieve separation columns is controlled by a thick\-film heater fabricated on polyimide foil. The chromatograph is equipped with two 16\-bits microprocessors communicating with the external portable PC. The instrument may operate in the on\-line continuous analysis mode."]
