The laboratory method of analysis that is accurate and precise for very low concentrations of carbon monoxide is:

Question

Quizplus · Accepted Answer

Gas chromatography is the most accurate and precise method for the analysis of very low concentrations of carbon monoxide. It can detect concentrations as low as parts per billion. Spectrophotometry is more applicable for the analysis of organic compounds and cannot detect very low concentrations accurately. Immunoassay is more suitable for the detection of specific compounds and may not be as accurate for the measurement of carbon monoxide. Potentiometry is used for the measurement of the potential difference between two electrodes and is not applicable for the analysis of carbon monoxide.
