Gas Diffusion Module
ASTM D7511-09 Standard Test Method for Total Cyanide by Segmented Flow Injection Analysis, In-Line Ultraviolet Digestion and Amperometric Detection This is a new standard test method that was developed by ASTM Committee D19 on Water to determine the concentration of total cyanide in drinking and surface waters, domestic wastewater, and industrial wastewater. Cyanide ion (CN-), hydrogen [...]
Docket ID No. OW-2003-0070 Comments Related to the Proposed Cyanide Determination Methods Federal Register / Vol. 69, No. 66 / April 6, 2004 / Proposed Rules, pp. 18166 – 18226 Prepared by: Emil Milosavljevic, Ph.D. and Ljiljana Solujic, Ph.D. Distillation-based methods for determination of operationally defined cyanide have very limited application because of the serious interferences from the species likely [...]
Gas diffusion modules are used in autoanalyzers whether segmented flow analysis (SFA), sometimes referred to as continuous flow analysis (CFA), or flow injection analysis (FIA). The purpose of the gas diffusion module is to function as an in-line cleanup eliminating particulates, potential ionic interferences and chemical complexes. The target analyte permeates through the membrane into a [...]
