The measuring complex of a mobile laboratory should include a sampling probe, 6 gas analyzers, by definition, in atmospheric air oxides of nitrogen, sulfur, carbon, dust, hydrogen sulfide and hydrocarbons, a portable spectrophotometer to determine sulfates, chlorides, nitrates, nitrites, ammonium, phosphates, iron, copper, zinc, lead, cyanide in water and soil, pH-meter to determine the acidity and alkalinity of the environment.
The system itself consists of a syringe pump programed to deliver solvent to the sampling probe, tubing conduits integrated with a fast two-way pinch valve to control solvent transport to and from the tissue, and a three-dimensional printed probe for direct sampling from the tissue (1).
