Test papers for qualitative determinations

These test papers allow the qualitative determination of ions and chemical compounds. They are used to detect, if compounds tested for are present above a specific detection limit. Some of the papers have specific applications:

Test papers for criminal investigations

Peroxtesmo KM detects blood traces. It is sensitive for peroxidase. A wet sample is soaked in water for about 1 minute and then placed on the test paper. A coloration of the test paper clearly indicates the presence of blood.

Phosphatesmo KM is used to detect sperm spots. It is specific for acid phosphatase. The test gives a clear early indication whether suspicious samples contain sperm or not. However, the reaction is not a suitable substitute for microscopic determination of live spermatozoa.

These test papers can easily be used on the crime scene. They can provide very early indications and supply the investigators with useful, preliminary information. This accelerates investigations in their critical beginning.


Test papers for milk analysis

Peroxtesmo MI detects lactoperoxidase in milk. It is an accepted indicator to distinguish between raw milk and high heated milk. In contrast to liquid indicators based on guaiacol, Peroxtesmo MI dose not smell and comes without hazardous reagents which is convenient and safe for the user.

Phosphatesmo MI is used to detect alkaline phosphatase in milk. The test is suitable as a rapid test for successful pasteurization of milk.


Water test papers

WATESMO  is for the detection of water in the liquid as well as the vapor phase. On contact with water the test paper changes color from light blue to dark blue.

WATOR is a special presentation of WATESMO for the dairy industry. The shelf life of butter is closely connected to the size of the containing water and buttermilk droplets. Manufacturers use WATOR to check the water distribution in butter prior to storing large quantities. On contact with water thelight blue paper develops dark blue spots. Size and number of these spots are correlated to the distribution of water.


Test papers for oil and oil-tanks

Oil test paper is recommended for the rapid determination of oil contaminations in water and soil. On contact with oil the paper turns dark blue.

AQUATEC allows the easy and reliable detection of water at the bottom of petrol and fuel oil tanks. It is also suitable to measure the thickness of oil layers in oil separators.

For a comprehensive overview on the applications of the different test papers, test strips and pH-papers please see the application guide on page3.
