FIELD: medicine. ^ SUBSTANCE: concrement with weight 20 mg is dissolved in 10 M solution of hydrochloric acid and series of said solution dilutions, C1=10-6 M, C2=10-5 M, C3=10-4 M, C4=10-3 M, is prepared. Through solutions, placed in interelectrode space of sensor, electric current 1=270 mA is sequentially passed, and work, spent on passage of electric current through volume of liquid with concrement solution in hydrochloric acid, sequentially to each concentration, is registered. ^ EFFECT: by results of carried out measurements diagram of work dependence on substance concentration at given current value is built, obtained diagram is compared with standard and by likeness of curves conclusion about salt composition of concrement is made. ^ 4 dwg, 1 ex |
