APPARATUS AND METHOD FOR DETERMINING TOXICITY OF LIQUID MEDIA Russian patent published in 2014 - IPC G01N33/18 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to determination of toxicity and can be used extensively in analysis when determining toxicity of different liquid media without using expensive and laborious analysis methods. More specifically, the group of inventions relates to aqueous toxicology and determination of toxicity of aqueous media and samples. Disclosed is a kit for determining toxicity of a liquid medium in the absence of a biological object test function units of at least one biological effect, comprising: a set of cross-sensitive sensors for obtaining signals proportional to physico-chemical parameters of said liquid medium, wherein at least one sensor from said plurality has a polymer membrane containing as an active component a compound selected from a group comprising tetradodecylammonium bromide (TDAB), trioctylmethylammonium (TOMA) chloride, oleic acid, 1-hexadecanol, gallic acid, phosphoric ester, dipicolinic acid diamide (2,6-pyridine carboxylic), phosphine oxide, metalloporphyrin, calixarene; and a calibration model which establishes a relationship between values said signals in the absence of a biological object and toxicity, obtained on samples of the liquid medium using the biological object. Also described is a multi-sensor, a method of calibrating the multi-sensor and a method for qualitative and quantitative determination of toxicity of liquid samples.

EFFECT: faster, easier and cheaper analysis.
