How to fill out method 5035 closed-system purge-and-trap

1. Step 1: Gather all the necessary equipment and materials including the closed-system purge-and-trap instrument, sample vials, septa, calibration standards, and appropriate gases.
2. Step 2: Ensure that the purge-and-trap instrument is properly connected to the gas supply and waste disposal system.
3. Step 3: Prepare the sample vials by inserting the septa and labeling them accordingly.
4. Step 4: Prepare the calibration standards by accurately measuring the required amounts of analytes and diluting them with appropriate solvents.
5. Step 5: Turn on the purge-and-trap instrument and allow it to reach the desired operating temperature.
6. Step 6: Place the prepared sample vials in the instrument's sample tray or holder.
7. Step 7: Set the instrument parameters such as purge time, trap temperature, and sample cycle.
8. Step 8: Start the purge cycle to remove volatile analytes from the sample vials and transfer them to the trap.
9. Step 9: After the purge cycle, initiate the desorb cycle to release the trapped analytes from the trap and transfer them to the analytical column for separation and detection.
10. Step 10: Monitor the chromatographic signals or detector response to identify and quantify the target analytes.
11. Step 11: Repeat the process with calibration standards to establish calibration curves for quantification.
12. Step 12: Analyze the results and report the concentrations of target analytes in the original samples.
