Product catalog summary

Manufacturing and Contact Information:
Manufactured by Uniphos Envirotronic Pvt. Ltd, located in Gujarat, India, with a marketing office in Mumbai. Contact details include phone numbers and email for inquiries.

Document Revision:
Rev.02/Jan17

1. Application:
The detector tube is designed for detecting mercury vapor in air or technical gases.

2. Detector Tube Sampling Pump:
Compatible with various pumps such as KWIK DRAW, Gas-Tester® IIH, and others. Users should follow specific instructions for each pump.

3. Measuring Range:
The tube measures mercury concentrations from 0.012 ppm to 0.096 ppm, equivalent to 0.1 mg/m3 to 0.8 mg/m3, using 20 strokes. The formula for calculation is provided for different stroke numbers.

4. Chemical Reaction and Color Change:
The reaction involves mercury and copper iodide, resulting in a color change from greyish white to light reddish yellow.

5. Ambient Conditions During Sampling:
Effective use is between 10°C and 40°C and 10% to 80% relative humidity. The tube should not be used if the protective layer is wet.

6. Interferences and Cross Sensitivities:
No interference from common gases like hydrogen, methane, and carbon monoxide. However, chlorine, bromine, and nitrogen dioxide can affect the mercury indication even at low concentrations.

Information Data Sheet Detection of mercury (Hg) vapor in air or in technical gases. KWIK DRAW(formerly MSA AUER) Gas-Tester® IIH, Gas-Tester® I / ThumbPump™-Sampler, Toximeter® II, Uniphos Kwik-Draw™-Pump or other suitable detector tubes pumps. Observe respective instructions for use. 0.012 ppm ... 0.096 ppm mercury at n=20 (20 strokes); equivalent to: Any number of strokes from 5 to 20 can be chosen. For calculation use n=20 scale, relate at follows: Reaction of mercury with copper iodide forming a complex copper-mercury iodide compound. Color change: Greyish white ^ Light reddish yellow. 5. Ambient Conditions During Sampling Detector tubes can be used without compensation of the reading between 10°C and 40°C (50°F and 104°F) and between 10% rh (0.9 g/m3 at 10°C [50°F]) and 80% rh (41 g/m3 at 40°C [104°F]). Do not use detector tube if protective layer has totally changed from dry to wet by water vapour. - hydrogen, methane, ethane, propane, carbon monoxide, carbon dioxide. - higher saturated hydrocarbons (e. g. hexanes, octanes), olefinic hydrocarbons (e. g. ethylene), aromatic hydrocarbons (e. g. benzene), alcohols, ketones, ethers, esters up to 1000 ppm. - hydrogen sulfide, ammonia up to 100 ppm - sulfur dioxide, hydrogen chloride, hydrogen cyanide up to 5 ppm. b) Chlorine, bromine, nitrogen dioxide will shorten stain length of mercury indication even in concentrations lower than 1 ppm.
