Hydrazine Standard Analysis Method

  1. Feb 15, 2017 #1
    The standard method for hydrazine analysis published by the National Institute of Occupational Safety and Health (NIOSH) presented a methodology I found a little bit confusing. The first four steps of the procedure are as follows:

    1. Connect the outlet of the sampler and the inlet of the pump to a tube packed with glass wool to
    protect the pump from splashover.
    2. Calibrate the personal sampling pump with sampler in line.
    3. Sample at 0.2 to 1.0 L/min for a sample size of 7 to 100 L.
    4. Transfer the solution from the bubbler to a glass vial, rinsing both the bubbler stem and body
    with 1-mL portions of 0.1 M HCl. Cap the vial securely for shipment.

    Also, is there any alternative method for measuring hydrazine using gas chromatography flame ionization detectors (GC-FID)?

    I am having a difficult time visualizing step 1 in particular. Is there anyone that may help provide clarification, hopefully with a diagram of some sort? It would be very much helpful.

    Thank you and have a good day!

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.
