METHOD OF DETERMINING SOLID RESIDUE IN A LIQUID |
摘要 |
chemical-ecology analyses. SUBSTANCE: liquid is preliminarily filtered and sample of it in amount of 1-3 mcl is applied on piezoelectric AT-cut resonator with frequency at least 5 MHz. Resonator frequency changes DELTAf1 and DELTAf2, are determined before and after vaporization of liquid, respectively. Weight of sample and solid residue therein are calculated in terms of formula presented in description. EFFECT: accelerated analysis and increased determination accuracy. |
