Agilent, 19231-60660, PRT sensor for electron capture detetctor (ECD) and COC inlet, used with series 5890 gas chromatography systems, all models

The Agilent PRT Temperature Sensor is a replacement temperature-sensing component for selected heated assemblies of the Agilent 5890 Series gas chromatograph. The sensor is used with the electron capture detector (ECD) and cool on-column (COC) inlet configurations identified for this GC platform. A platinum resistance temperature sensor provides electrical feedback that supports the instrument's temperature control circuitry. Reliable temperature sensing is essential to maintaining reproducible detector and inlet conditions during chromatographic analysis. This replacement component is intended for repair when a sensor-related fault or service inspection identifies a defective temperature measurement element. Use the correct 5890-series service documentation to locate the sensor, establish safe instrument shutdown and reinstall the component without stressing the wiring or connector. Following replacement, check temperature readings and verify the heated assembly's regulation before running analytical samples. The PRT sensor is not an ECD cell, a detector radioactive source or a column temperature probe for unrelated GC models. Match the existing sensor assembly to the instrument's inlet or detector configuration before servicing.
