alcohol testers

Swedish scientists have developed new methodology for determining the presence of drugs in the organism. Whereas existing methods require blood or urine test, the new method is very simple and consists in the analysis of exhaled air, just as checks of drivers with alcohol testers traffic cops around the world.

Through analysis of air exhaled by man is determined not only drunk drivers - in recent years, scientists have learned in such a way to diagnose asthma, diabetes and even certain types of cancer.

But researchers from the Swedish Research Center Karolinska Institutet have developed a method for rapidly and, most Vardenafil Drug By Bayer Pharmaceuticals importantly, very accurately determine the presence of the organism even small traces of drugs.

Scientists invited to participate in the study of volunteer addicts, who was hospitalized in a hospital in Stockholm with the symptoms of overdose of amphetamines. After some time, and after the patients began a normal feeling, the researchers asked the subjects to put on face masks and specially designed to be in them for 10 minutes. Then the masks Tadalafil Online Medicine - You Can! removed filters and subjected them to analysis by gas-liquid chromatograph and mass spectrometer. Instruments showed the presence of minute quantities of amphetamine, although since the last drug injection patients had passed a few weeks, and the traditional urine and blood samples were negative.

"These results are very promising. For the first time in the world we have created a technique allows to obtain very reliable data on the presence in the body of drugs. The compact device such as alcohol testers, but also to determine the drug in the exhaled air can be very useful for the police," - says Olof Beck, who led the study.
