D3986:17

Standard Test Method for Measurement of Fluorides in Workplace Atmospheres by Ion-Selective Electrodes

This test method covers the determination of dissolved and total recoverable barium in brines, seawater, and brackish waters by direct-current argon plasma atomic emission spectroscopy (DCP–AES). This test method has been tested in the range from 10 mg/L to 20 mg/L. Samples shall be diluted to contain concentrations within the calibration range. Higher concentrations can also be determined by changing to a less sensitive emission line.

Analysis Type (Application Method): Atomic emission spectroscopy

Compatible Filters:

Groundwater sampling capsules or portable vacuum filter holder with hand vacuum pump. Filtering in field at time of collection. Any 0.45 μm filter that will not contribute/remove metals. An example would be an IC Millex® filter. Forceps to handle filter membrane.
