Gas Chromatography and Diode Array Detection for the Direct Measurement of Carbon Disulfide in Challenging Matrices

Abstract

A fast and reliable gas chromatographic technique for the direct measurement of parts-per-billion level of carbon disulfide in various segments such as hydrocarbon processing, flavour and odour, food packaging, and environmental applications is introduced. The analytical approach incorporates temperature-programming capillary gas chromatography for the fast separation of carbon disulfide using a recently introduced inert 6% cyanopropylphenyl and 94% dimethylpolysiloxane column. A newly commercialized diode array detector was employed for analyte detection. Due to its universal response to organic compounds, a flame ionization detector was incorporated in series with the diode array detector to provide additional analytical information without incurring extra time or analyses. With this approach, a complete analysis is accomplished in less than 5 min. Carbon disulfide is measured directly without the need for pre-concentration, derivatization or specialized detectors with a detection limit of less than 100 µg/m3. A relative precision of less than 5% RSD (n=10) over a range from 51 pg to 106 ng (on column) of carbon disulfide with correlation of coefficient of greater than 0.9993 was obtained.
