GC Analysis of Methylcyclohexane Methanol (MCHM) and Propylene Glycol Phenyl Ether (PPH) in Water on VOCOL® after SPME using 100 μm PDMS Fiber

GC Analysis of Methylcyclohexane Methanol (MCHM) and Propylene Glycol Phenyl Ether (PPH) in Water on VOCOL® after SPME using 100 μm PDMS Fiber

Conditions

sample/matrix MCHM and PPH at 1 µg/L in 6 mL water, 25% sodium chloride
desorption process 2 min, 270 C (splitter open at 0.75 min)
extraction 5 min, headspace at 55 C, with agitation
SPME fiber SPME Assembly, 100 µm PDMS FS, 24 ga, Auto (Red) (57301)
column Vocol, 20 m x 0.18 mm I.D. x 1.0 µm (28463-U)
oven 50 C (1 min), 15 C/min to 220 C (5 min)
carrier gas helium, 1 ml/min constant
injection SPME
liner 0.75 mm I.D., SPME
inj. temp. 270 C
detector MSD, selected ion mode
MSD interface 220 C
scan range selected ion mode; m/z=110, 97 (MCHM) and m/z=94, 152 (PPH)

Description

Analysis Note In this application, an SPME method was developed for the analysis of two compounds involved in the chemical spill into the Elk River in West Virginia, which took place in January 2014. The method could easily detect both MCHM and PPH at a level of 1 μg/L from spiked surface water.
