Standard Measuring Range : 0.2 to 10 ppm
Number of Strokes (n) : 20
Time for Measurement : app. 3 min
Standard Deviation : ± 20 to 30 %
Colour Change : white -> yellow
Ambient Operating Conditions - Temperature : 10 to 40 °C, Absolute Humidity : 5 to 15 mg H2O / L
Reaction Principle - CICOOR + 4-(4-Nitrobenzyl)-pyridine -> yellow reaction product
Cross Sensitivity - Methyl, ethyl and isopropylchloroformate are indicated with approximatelythe same sensitivity. It is impossible to differentiate betweenthem. Petroleum hydrocarbons, aromatics, alcohols and ketones do notinterfere in the TLV range. It is impossible to measure chloroformates in the presence ofphosgene.

Discoloration compared tocolour standard.
Number of Strokes (n) : 200
Time for Measurement : app. 50
minStandard Deviation : ??30 %
Colour Change : white ->blue
Ambient Operating Conditions - Temperature : 15 to 30 ?C, Absolute Humidity : 3 to 15 mg H2O / L
Reaction Principle - Dimethyl sulphate + 4-(4-Nitrobenzyl)-pyridine -> colourless alkylation product colourless alkylation product -> blue reaction product
Cross Sensitivity - Phosgene and chloroformates give a yellow discoloration and it isimpossible to make a dimethyl sulphate measurement.Alcohols, ketones, aromatics and petroleum hydrocarbons in theTLV range do not interfere.
Additional Information - After performing the required 200 pump strokes the reagentampoule must be broken. The liquid of the ampoule must betransferred to the indication layer and carefully drawn through itusing the pump. Wait five minutes before evaluating the indication.The tube must not be left in direct sunlight during the 5 minuteswaiting time.
