Draeger Tube Phosphoric Acid Esters 0.05/a 6728461

Description

The Draeger Tube Phosphoric Acid Esters 0.05/a 6728461 is high precision. The Dräger sampling tubes and systems provide very reliable results, even with complex compounds and mixtures of substances.

Application Range

• Standard Measuring Range: 0.05 ppm Dichlorvos
• Number of Strokes n: 10
• Time for Measurement: approx. 5 min
• Standard Deviation: ± 30 %
• Color Change: yellow → red

 

Ambient Operating Conditions

• Temperature: 10 to 40 °C
• Absolute Humidity: 3 to 18 mg H₂O / L

 

Reaction Principle

• (CH3O)2PO2-CH=CCI2 + Cholinesterase → inactive enzyme
• Butyrylcholine iodide + H2O → Butyric acid
•  Butyric acid + Phenol red → yellow reaction product

If phosphoric acid esters are present the enzyme is inactivated and butyric acid will not form, thus the weak alkali solution colors the indicating layer red and must be stable for 1min. If the enzyme remains active, phosphoric acid esters are not present, and the indicating layer remains yellow because of butyric acid formation.

Cross Sensitivity

Other phosphoric acid esters than dichlorvos are also indicated, but with different sensitivities.

Additional Information

After performing the required 10 pump strokes the reagent ampoule must be broken and the liquid transferred to the enzyme layer by gently tapping the side of the tube. The substrate layer must not become wet After waiting one (1) minute the liquid must be carefully drawn up to the marking line using the pump. Wait another minute before drawing the liquid onto the indication layer using the pump.
