[Determination of the butyl 2,4-dichlorophenoxyacetate in the workshop by gas chromatography].
The new method for determining the content of 2,4-dichlorophenoxyacetic acid butyl ester in the workshop by using gas chromatography is presented. The experiments for precision and efficiency have been performed. The range of determination is 0.05-2.5 mg/m3. The minimum detectable mass concentration is 25 micrograms/m3. The method meets the requirement of the "monitoring and researching standard for toxic substances", and shows that it can be applied in routine analysis.
