• Allows the quick and easy detection of hydrogen sulphide, which occurs in the processing of raw oil. It is toxic even in low concentrations. Therefore, critical points are carefully checked. Sulfide containing solutions also give a positive reaction

• Allows the quick and easy detection of nickel

• For non-destructive testing of materials, apply a drop of 3% Nitric acid (1 part Nitric acid 85%, 5 parts water) to the degreased surface. After 1 minute, absorb the liquid with the test pape

• Allows the reliable detection of Nitrate and Nitrite

• Shows different colors for the two ions

• Virage Nitrate: white to red (dip test paper into sample and afterwards into sulfuric acid 96%)

• Virage Nitrite: white to ye

• Allows the rapid detection of sulphite and sulphur dioxide

• Used in food analyzing laboratories

• The reaction is as follows: 2 IO3- + 5 SO32- + 2 H+ to 5 SO42- + I2 + H2O

• Sulphurous acid or sulphites reduce potassium i

• Allows the quick and easy detection of strong oxidizers such as nitrite and free chlorine

• Sodium and heavy metal ions decrease the sensitivity. The leaflet describes a method to eliminate these interferences

• Color reaction: bright-yel

• Allows the quick and sensitive detection of blood traces

• In criminal investigations, it is used as a rapid screening test

• The test paper uses the pseudo-peroxidatic effect of blood. The material in question is allowed to soak i

• Allows the quick and easy detection of peroxidase in food

• It is used in the food processing industry to evaluate the quality of canned food

• A drop of the sample is put onto the test paper. Alternatively, the paper can be presse

• Allows the specific detection of lactoperoxidase in milk

• In the dairy industry, the test is used for the quick and easy quality control of highly heated milk
