Micro-machined for highest reliability and extremely fast results
The faster separations enabled by narrow-bore capillary GC columns are fully exploited when all components in the sample flow path are miniaturized. The micro-machined injector and thermal conductivity detector (TCD) of the Agilent 490 Micro GC, together with a narrow-bore column, PLOT or micro-packed column, yield extremely rapid gas separations in seconds.
Micro-machined Injector
The silicon micro-machined injector has no moving parts for high dependability while including the features you expect. Software selectable injection volumes from 1 µL to 10 µL cover a wide range of applications requirements. Optional backflush capability protects the analytical column from excessive wear and tear. The injector can be heated to 110 °C to eliminate discrimination of higher hydrocarbons for improved performance.
Micro-machined Thermal Conductivity Detector (TCD)
The small 200 nL internal volume of the micro-machined TCD eliminates peak broadening, providing better data quality and easier quantitation. The detection limit ranges from 1 ppm for capillary columns to 10 ppm for “micro-packed” columns (component dependent).
