Procedure

1. Prepare instrument as outlined in the operator’s instruction manual (perform maintenance and

leak checks, etc.).

2. Purging and analyze blanks until instrument is stable (nitrogen results will reach a plateau),

3. (4-5) blanks and (1-2) waste samples to condition the instrument

4. 3 samples of calibration substance to check or carry out the calibration;

5. Test 9 samples

6. 2 samples of calibration substance to check the calibration;

7. Repetition of point 5 to point 6 until all samples are processed;

Note: Do Calibrating refer to operator’s instruction manual for details.
