1.1 This practice covers the use of an electron-capture detector (ECD) as the detection component of a gas chromatographic system.

1.2 This practice is intended to describe the operation and performance of the ECD as a guide for its use in a complete chromatographic system.

1.3 For general gas chromatographic procedures, Practice E 260 or Practice E 1510 should be followed except where specific changes are recommended in this practice for use of an ECD. For a definition of gas chromatography and its various terms, see Practice E 355. These standards also describe the performance of the detector in terms which the analyst can use to predict overall system performance when the detector is coupled to the column and other chromatographic components.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific safety information, see Section .
