Method 1610 is used for the determination of ethyl ether by GC/FID. The sample is collected on charcoal sorbent tubes, desorbed in ethyl acetate, and analyzed. The working range is 100 to 2700 mg/m³ (33 to 880 ppm). A sampling period of 15 minutes may be monitored for STEL (short term exposure limit) compliance using a flow rate of 0.2 L/min. During sampling, high humidity may greatly reduce the breakthrough volume. NOTE: This method revises Method S80.
