01 Solution Summary
For GC-ECD configuration selection for nitrobenzene compounds in surface water samples, analysis is performed using a gas chromatography route. Samples enter the chromatographic flow path through a liquid autosampler, the column separates target components from matrix interferences, and the ECD records the response. Quantitation and quality control are arranged as follows: for GC-ECD configuration selection for nitrobenzene compounds in surface water, use reference materials matching the detection channel to establish a calibration relationship; the qualitative basis, quantitation method, and result units are subject to the applicable method; blanks, calibration checks, duplicates, and QC samples form batch quality control. The analysis batch also includes blanks, calibration checks, and applicable QC samples.
