instruction:
In this task, you are given a question and answer options for that question. Using this information, you have to classify each text into different topics: medicine, nursery, psychology, chemistry, pharmacology, biology.
question:
Question: With respect to the distribution coefficient of a solute between two partially miscible liquids:
Options: <0> Because it is a quotient between solute concentrations in the two phases, it is independent of temperature. <1> It does not depend on the total amount of solute in both parts. <2> It is useful to determine the molar mass of the solute. <3> If one phase is water and the other an organic solvent, it is usually used in medical and environmental chemistry to know the distribution of drugs and contaminants between these two types of media. <4> It only has physical significance when the liquid phases are in contact through a semipermeable membrane.
answer:
chemistry

question:
Question: A classification of gas chromatography detectors commonly found in the literature divides them into concentration and mass detectors, destructive and non-destructive, integral or differential and universal or selective. According to this classification:
Options: <0> The thermal conductivity detector is a selective detector. <1> The flame ionization detector responds to the concentration of the analyte. <2> The thermal conductivity detector responds to the concentration of the analyte. <3> The phosphorus and nitrogen detector (NPD) is a universal detector. <4> The thermocalorimeter detector is of the differential type.
