Determining EG using Surescreen alcohol saliva strips. Photos show zoomed-in images of the pad on the strips. (a) Successful conversion of EG with the alcohol oxidase in the pad of the strip (blue colour) and differentiation from glycerol, PG and DEG using 5% v/v of the alcohols in water. (b) Different percentages of EG spiked into neat PG. Limit of detection ~ 0.5% EG m/m.
