SiREM offers competitively priced specialty chemical analytical services to monitor remediation processes and progress including:
SiREM’s custom gas chromatographic dissolved hydrocarbon gases (DHG) analysis is based on a modified RSK-175 method developed by the US EPA. DHG analysis is used to quantify aqueous concentrations of methane, ethene, ethane and can also quantify propene.
Use SiREM DHG Quantification to:
Volatile fatty acids (VFAs) quantification in groundwater is used to assess electron donor status in bioremediation systems. When commonly used electron donors including lactate, emulsified vegetable oils (EVO) and alcohols are fermented to VFAs, it indirectly indicates hydrogen generation. Quantification of VFAs also provides additional insights into electron donor status compared to total organic carbon (TOC) analysis. SiREM uses a custom ion chromatographic method for VFA quantification, capable of quantifying lactate, acetate, propionate, formate, butyrate and pyruvate.
