英文摘要 | A modified miniaturized hydrogen flame ionization detector (m-FID) was developed and evaluated. An integrated nozzle assembly was constructed to solve the gas leakage caused by adhesive crack during repeated highlow temperature processes or vibration. An embedded sealing structure was designed to realize the face sealing, thus improving the sealing stability and reliability of the m-FID. Polyimide was employed as seal and insulation material to ensure the detector can be used at 300 & DEG;C for a long term. The hydrogen and air consumption of the m-FID was 12 mL/min and 110 mL/min, which is about 1/3 of the FID gas consumption of commercial laboratory instruments. The limit of detection (LOD) for n-hexadecane was 3.2 x 10-12 g/s, with a linear response range of nearly 5 orders of magnitude. Finally, it was installed onto an on-site gas chromatograph to detect drug samples with wide boiling point range from room temperature up to 535 & DEG;C. |
