Method 1301

Ketones II by GC/FID


This method is used for the determination of ketones. The sample is collected on charcoal sorbent tubes, desorbed with 1% methanol in carbon disulfide, and analyzed using GC/FID. This method was developed to give better desorption than obtainable with carbon disulfide extraction of the charcoal. This method can be used in paint and resin manufacturing plants. Note: This method combines and replaces Methods S10, S12, S13, S15, and S16.
