Determination of Sulfur in Natural Gas by ASTM Method D 6228-11

Current methods to measure worker exposure to chemicals generally involve collecting samples and sending them to a laboratory for analysis, which can take up to two weeks to obtain results. Tools that can turn samples into on-site information can provide data to make informed decisions when and where they are needed to protect workers.
